A. Color Choice
Seven different colors are used for EFIS system, plus two particular colors for sky and earth (blue and brown). An exhaustive list of all the ND indications with their color assignment is given in the following pages. The general rules for color choice below are followed:

red :
used for the flight envelope limit indications, and for the failure indications concerning the various sensors.
amber :
used for information or messages requiring attention but not quick action or decision.
yellow :
used for aircraft references (e.g.: aircraft symbol, lubber line...)

white :
used for scales, for VOR indications.
green :
used for current values (e.g.: ground speed, track). cyan : used for selectable values (e.g.: selectable speed, armed mode, tuned navaids), and units (e.g.: NM).
magenta :
used for ILS. (LOC and GLIDE SLOPE) deviations, and optional information displayed on the map: VOR-D, NDB, ARPT,...

White
Used for scales and VOR indications.
Green
Used for the current values (e.g. ground speed, track) and the data provided by the FMS (e.g. primary flight plan, deviations).
Cyan
Used for selectable values (e.g. selectable speed, armed mode, tuned navaids) and units (e.g. NM).
Magenta
Used for ILS (LOC and GLIDE SLOPE) deviations and optional information displayed on the map (VOR-D, NDB, ARPT).

B. Presentation Rules
Symbology used for the display of the different parameters is always the same, whatever the selected mode (e.g.: the selected heading symbol is the same in the ARC mode or the various ROSE modes).

A piece of information is always displayed at the same location on the image (e.g.:
the wind indication is always displayed in the left upper corner of the ND). The figure referenced below shows a typical ND image.

C. Failure Indications

(1) Failure concerning symbols currently on display
The relevant indication is removed.
For the significant sensor failures, a failure message is displayed, in red color (sometimes amber), clearly indicating what is the lost information. This message first flashes during a few seconds to draw the crew's attention, then remains steady as long as the failure is present. The warning announcement disppears as soon as the failure disappears or the DMC uses another source providing the valid parameter (e.g.: switching IRS3/IRS1).

(2) Failure concerning symbols not currently on display (e.g.: ILS failure in VOR mode). The flag does not appear on the DU.

** ON A/C NOT FOR ALL

3. ND Figurations

A. ND Modes
Each pilot has 5 different modes of presentation on his ND at his disposal:

ROSE-ILS
ROSE-VOR
ROSE-NAV
ARC
PLAN

(1) ROSE modes

Navigation Display ROSE VOR Mode (HDG Mode) ** ON A/C NOT FOR ALL

Navigation Display-ROSE NAV Mode ** ON A/C NOT FOR ALL

In the three ROSE modes, the ND provides a display which is similar to that of a conventional horizontal situation indicator, i.e. a rotating heading dial orientated to the magnetic north and giving to the pilot the A/C actual magnetic heading with as reference the fixed yellow lubber line (item a) at the top of the dial.

Navigation Display ROSE VOR Mode (HDG Mode) ** ON A/C NOT FOR ALL

The ND display is always heading up. A yellow A/C symbol (Item b) at the center of the dial, is fixed and pointed up to the lubber line.

Navigation Display ROSE VOR Mode (HDG Mode) ** ON A/C NOT FOR ALL

Small white triangles (Item c) are arranged in all 45° positions on the circumference with as reference the heading line.
They are fixed and do not turn with the heading dial.

Navigation Display ROSE VOR Mode (HDG Mode) ** ON A/C NOT FOR ALL

The map in ROSE NAV mode and/or the weather radar image is scaled according to the range mark value selected by the pilot on his EFIS control section.
Two range markers laid (Item d) on the 225° radial indicate the value in NM of the distance represented by the radius of the two range circles (inner and outer). These values are respectively the 1/4 and the 1/2 of the selected range (which represents a distance equal to that of the heading dial diameter).

Navigation Display-ROSE NAV Mode ** ON A/C NOT FOR ALL

Item e: magnetic track
The magnetic track is given by the ADIRU (label 317 and 320).
The losange is not displayed when the difference between the magnetic heading and the magnetic track angle is higher than 42°.

Item f: selected heading or selected track
The selected heading angle is given by the FCU (label 101) or the ADIRU (label 320)
The selected track is given by the FCU (label 114)

(a) ROSE VOR

Navigation Display ROSE VOR Mode (HDG Mode) ** ON A/C NOT FOR ALL

The pattern is nearly that of a standard HSI with a VOR course and lateral deviation.

(b) ROSE ILS

Navigation Display - ROSE Mode ILS ** ON A/C NOT FOR ALL

The pattern is nearly that of a standard HSI: LOC deviation and GLIDE slope.

Navigation Display-ROSE NAV Mode ** ON A/C NOT FOR ALL

It is a dynamic pattern which provides the A/C position with respect to the flight plan.
Item i: Ground speed
The ground speed is given by the ADIRU label 312

Item j: True air speed
The true air speed is given by the ADIRU label 210
Item k: Wind origin/force
The wind direction true is given by the ADIRU label 316
The wind force which follows the wind direction is given by the ADIRU label 315
Item l: analog arrow for wind direction
the arrow direction is a function of the wind direction label 316 and of the true heading label 314

(2) ARC mode

Navigation Display - ARC Mode ** ON A/C NOT FOR ALL

In this mode, the ND displays a 96° heading sector ahead of the A/C, giving the A/C actual magnetic heading with respect to the fixed yellow lubber line at the top of the scale. The A/C position on the map is represented by the fixed yellow A/C symbol located at the lower quarter and at the mid of the ND image (item b) pointing up to the magnetic heading reference line (item a)

Navigation Display - ARC Mode ** ON A/C NOT FOR ALL

This mode provides the pilot with map and weather radar information but limited to the forward 96° sector. Four arcs of a circle give range marks scaling the map according to the selected range value. Range marker values in NM are provided on the L and R lower radials making a 15° angle with respect to the horizontal for the second and the third inner arcs (item d). These range marker values are respectively equal to the 1/2 and 3/4 of the selected range, which represents the distance corresponding to the radius of the heading scale arc.

Navigation Display - ARC Mode ** ON A/C NOT FOR ALL

(3) Plan mode

Navigation Display - PLAN Mode ** ON A/C NOT FOR ALL

It enables the pilot to display a static map orientated with respect to the true North.
The map information displayed is the same as in ROSE-NAV or ARC mode, but not ahead of the aircraft:

the map is centered on a map reference point which is chosen by the pilot on his MCDU and which can be:

either the active point
or any other selected waypoint of the flight plan.

The scale of the map is that chosen by means of the range selector (the range value selected corresponding to the diameter of the outer circle).
No navigation station characteristics (in the ND bottom corners) and associated bearing pointers are available in this mode.
The A/C position on the map is represented by a track-orientated yellow A/C model (item b)

Navigation Display - PLAN Mode ** ON A/C NOT FOR ALL

(item g)
Ground speed and True air speed (refer to para. C) this information is the same in the other ND modes.
(item h)
Active way point data (refer to para. basic navaids) this information is the same in the other ND modes.

Item a: aircraft symbol
The aircraft position on the plan mode is given by th FMGC label 310, label 311, label 313.

(4) HDG and CHECK HDG flag
A red flag HDG appears in the upper part of the dial,

Navigation Display-HDG Flag ** ON A/C NOT FOR ALL

first flashing during 9s, then remaining steady when the DMC has detected an anomaly concerning the heading parameter.

When difference between the 2 sides is detected by external comparison (FWC), an amber CHECK HDG flag is displayed at the top of the CAPT and F/O ND dials.

Navigation Display-Feedback Messages and FWC Comparison Messages ** ON A/C NOT FOR ALL

Navigation Display-CHECK HDG Flag ** ON A/C NOT FOR ALL

The heading remains still displayed. The crew has to give a decision, using the ADIRU 3, heading source or the standby compass.
HDG and CHECK HDG flags are not displayed in the PLAN mode.

(5) Runway (RWY) Condition

Navigation Display (ND) - Runway (RWY) Condition Information ** ON A/C NOT FOR ALL

Dedicated selector lets the crew select the RWY condition. It is possible to select the DRY or WET runway condition. The RWY condition is shown on the ND, in all modes (ARC, ROSE VOR/ILS, ROSE NAV and PLAN) and also when the ANF is shown on the ND. Selected RWY condition is shown on the ND in white at the top of the ND display.

B. Heading or Track Presentation

(1) Actual heading
The A/C actual magnetic heading is readable around a graduated rotating scale (only for a 90° sector ahead of the A/C in ARC mode), with respect to a fixed yellow reference line at the top of the scale.
Above 73°N or 60°S the white TRU indication is displayed to indicate true heading

Navigation Display - ARC Mode ** ON A/C NOT FOR ALL

In case of heading failure, the scale is cancelled as well as the selected track and heading symbols, which cannot be set any more.

(2) Actual heading
The A/C actual magnetic heading is readable around a graduated rotating scale (only for a 96° sector ahead of the A/C in ARC mode), with respect to a fixed yellow reference line at the top of the scale.
Above 65°N or 65°S the white TRUE indication is displayed to indicate true heading

Navigation Display - ARC Mode ** ON A/C NOT FOR ALL

In case of heading failure, the scale is cancelled as well as the selected track and heading symbols, which cannot be set any more.

(3) Actual track
The A/C actual track is represented by a green diamond-shaped symbol (item e) on the heading scale (inside).
This symbol consists only of an outline.

Navigation Display ROSE VOR Mode (HDG Mode) ** ON A/C NOT FOR ALL

It disappears in case of failure.

(4) Selected heading or track
The selected heading or track (item f) is represented by a cyan triangle on the heading scale, outside. It is represented by digits in ARC mode if the selected value differs from the actual magnetic heading for more than 42°.

This digit is displayed on the left or on the right end of the HDG scale depending on the value of the difference between the actual HDG or track and the selected HDG or selected track.

Navigation Display - ROSE Mode ILS ** ON A/C NOT FOR ALL

Navigation Display - ARC Mode ** ON A/C NOT FOR ALL

The symbol disappears in case of failure.

(5) Selected heading or track
The selected heading or track (item f) is represented by a cyan triangle on the heading scale, outside. It is represented by digits in ARC mode if the selected value differs from the actual magnetic heading for more than 48°.

This digit is displayed on the left or on the right end of the HDG scale depending on the value of the difference between the actual HDG or track and the selected HDG or selected track.

Navigation Display - ROSE Mode ILS ** ON A/C NOT FOR ALL

Navigation Display - ARC Mode ** ON A/C NOT FOR ALL

The symbol disappears in case of failure.

C. Speed and Wind Indications
In any of the ND modes, the following data are displayed on the L upper corner of the ND:

ground speed (item i)
Navigation Display-ROSE NAV Mode ** ON A/C NOT FOR ALL
Navigation Display-ROSE NAV Mode ** ON A/C NOT FOR ALL
true air speed (item j)
Navigation Display-ROSE NAV Mode ** ON A/C NOT FOR ALL

D. ADF-VOR Bearing and Characteristics of the NAV Stations

(1) Selection and display control

Navigation Display - PFD/ND Control

Each pilot has at his disposal two 3-position switches, VOR(1), OFF, ADF(1) and VOR(2), OFF, ADF(2).

Thus it is possible to display on each ND the following arrangements:
VOR(1)
VOR(1), ADF(2)
VOR(1), VOR(2)
ADF(1)
ADF(1), ADF(2)
ADF(1), VOR(2)
VOR(2)
ADF(2)
When a pilot sets a switch to VOR or ADF for display, the following data are displayed in all the modes except in the PLAN mode:

characteristics of the station
bearing needles

always in the same color:

white for VOR
green for ADF

(2) NAV station ident/frequency/tuning Mode
The VOR, DME, station tuning and the selection of the station for display is normally made automatically as the A/C flies along the flight plan.
At any time the pilot can override the automatic selection and manually select a desired station through the MCDU in the RADIO NAV page.

Navigation Display - MCDU RADIO NAV Page ** ON A/C NOT FOR ALL

(3) hkl
At last if both FMGCs have failed, the pilot can perform the station selection through the RMP in the NAV back-up mode.
The ADF station tuning and the selection of the station for display obey the same principles, except that the automatic tuning selection for display, is only made for the station specified for an approach.

The features of the selected navaids are displayed in one of the lower corners of the ND (only by action of the pilot on the 3 positions switches), left for side 1, right for side 2:

E. Radio Deviation Indications: VOR, LOC, GLIDE SLOPE

(1) In ROSE VOR mode

Navigation Display - ROSE VOR Mode ** ON A/C NOT FOR ALL

A cyan dagger shaped symbol (item ae) indicates the selected VOR course on the heading dial. The VOR course is selected either automatically when the A/C follows a specified VOR course on a leg of the flight plan, or manually through the MCDU in the RADIO NAV page, or through the RMP in back-up mode.
The central part (in cyan color) of the course symbol provides the lateral VOR deviation (item x) on a scale which is perpendicular to the course symbol. This scale (item y) has 2 dots on each side. The outer dots represent a plus or minus 10° deviation. Furthermore an arrow on the deviation bar gives the TO/FROM indication (item z).

Item x: Lateral deviation bar
This lateral deviation is given by the ILS label 173, the VOR label 100 and label 222, the ADIRU label 320
Item y: Deviation scale
The deviation scale is given by the ILS label 105, the VOR label 100 and the ADIRU label 320
Item ae: Selected course
The selected course is given by the ILS label 105, the VOR label 100, the ADIRU label 320

Item x: Lateral deviation bar
This lateral deviation is given by the ILS label 173, the VOR label 100 and label 222, the ADIRU label 320
Item y: Deviation scale
The deviation scale is given by the ILS label 105, the VOR label 100 and the ADIRU label 320
Item ae: Selected course
The selected course is given by the ILS label 105, the VOR label 100, the ADIRU label 320

If the VOR course parameter or the magnetic heading is not valid, the course pointer is constantly displayed in the vertical position (scale in horizontal position), in red color.

The VOR lateral deviation is then equal to:

VOR bearing minus course if the magnetic heading is not valid
VOR bearing minus magnetic heading if the VOR course is not valid.

When the VOR bearing parameter SSM changes from NO to NCD, the associated deviation index is still displayed during 3 s, in its last valid position, in order to avoid the beating of the index at the limits of reception, and it disappears afterwards.
The selected VOR station (item aa) (1 for CAPT side and 2 for F/O side), frequency (item ab) selected course (item ac) and identification (item ad) M or R, when available are provided in the right upper corner of the ND.
The displayed indications are in white color.

Navigation Display - ROSE VOR Mode ** ON A/C NOT FOR ALL

Item w: VOR bearing The VOR bearing is given by the VOR label 222 and ADIRU label 320
The ADF bearing is given by the ADF label 162

Item ab: VOR frequency
The VOR frequency is given by the VOR label 034
The ADF frequency is given by the ADF label 032

In case of failure, they are displayed in red color, and in addition the selected VOR course is replaced by a "xxx" symbol. In case of NCD the selected VOR course is then replaced by a "---" symbol in cyan color.

(2) In ROSE VOR mode

VOR bearing minus VOR course if the VOR course parameter is valid
VOR bearing minus magnetic heading if the VOR course or the heading is not valid.

Navigation Display - ROSE VOR Mode ** ON A/C NOT FOR ALL

(3) In ROSE ILS mode

Navigation Display - ROSE Mode ILS ** ON A/C NOT FOR ALL

If an ILS station frequency and course have been selected:

a dagger-shaped pointer (item ae) in magenta color points to the selected ILS course. Its central part is the lateral deviation bar (item af) which can move on a scale (item ag) which is perpendicular to the pointer, and has 2 dots on each side. The position of the bar on the scale gives the localizer deviation. The extreme dots correspond to plus or minus 0.155 ddm.

a magenta lozenge (item ah) gives the glide slope deviation on a vertical scale (item ai) at the right of the heading dial, provided that the A/C is within the conditions of reception of the ILS glide slope signal.

Item ae: Selected course
The selected course is given by the ADIRU label 320 and the ILS label 105
Item af: Lateral deviation bar
The lateral deviation is given by the ILS label 105 and label 173, by the VOR label 100 and label 222, the ADIRU label 320 is also concerned.
Item ag: Deviation scale
The deviation scale is given by the ILS label 105, the ADIRU label 320 and the VOR label 100
Item ah: Glide slope deviation
The glide slope deviation is given by the ILS label 174

If the ILS course parameter or the magnetic heading is not valid, the course pointer is constantly displayed in the vertical position, in red color.
When the LOC or the glide slope deviation parameter SSM changes from NO to NCD, the associated deviation index is still displayed during 3s, in its last valid position, then it disappears (for the same reason as VOR mode).

Navigation Display - LOC and G/S Deviation in NCD ** ON A/C NOT FOR ALL

A red LOC flag appears in the center of the ND as soon as the frequency or deviation information has failed.
In case of excessive deviation with respect to the glide path, the white scale and the magenta lozenge pulse.
The G/S deviation indication and the scale disappear as soon as one of the following pieces of information has failed: frequency or deviation. Then a red G/S flag is displayed at their location.
The same information as in ROSE VOR mode is provided in the right upper corner, in magenta color, but concerning the selected ILS station (ILS1 for F/O ND and ILS2 for CAPT ND). Only the CRS symbol and the ILS1 or ILS2 symbols are in white.

When the information "BACK BEAM/BACK COURSE" is transmitted by the FMGC, the deviation on the LOC scale is reversed, the message B/C is displayed in magenta and the G/S scale disappears.

I. Map Information - Basic Navaids

NOTE: This indication is provided at the bottom of the ND image in the PLAN mode.

(1) General

Navigation Display - Basic Navaids ** ON A/C NOT FOR ALL

There are different types of basic navaids: current waypoints (item am), TO waypoint (item an), navigation stations (item bi), airports (item ap), holding patterns and procedure turns.
A waypoint can be any navigational aid or another point selected by the pilot.
The various kinds of waypoints are different in shape and in color.
Waypoints can be constrained. In this case they are indicated by a circle surrounding the waypoint symbol. This circle is:

in white color if the constraint is not concerning the flight plan
in magenta if the constraint is of concern for the flight plan and can be respected
in amber color if the constraint is of concern for the flight plan but cannot be respected.

The navaids which are automatically tuned or those which are manually selected for display, are indicated on the map in cyan color. Level points (which are points of the flight plan where a selected flight level is be reached), speed change points, constrained waypoints are indicated on the flight plan by means of specific symbols:
respectively arrow, small circle, large circle surrounding the way point.
These symbols are in magenta color when associated to a constraint.

(2) Current waypoints
(item am)

Navigation Display - Basic Navaids ** ON A/C NOT FOR ALL

They are the points of the map, linked by segments, which belong to active flight plan. They are displayed in a green diamond-shaped symbol. All the waypoints which are stored in the FMGC data base and which are not already presented with the flight plan, are displayed.

(3) TO waypoint
(item an)

Navigation Display - Basic Navaids ** ON A/C NOT FOR ALL

It is normally the next one to be overflown. It is displayed in white; the waypoint identification (max 6 letters) is written next to the corresponding waypoint symbol, with possibly the associated constraints below if the CSTR option is selected (this concerns only the TO and the next waypoints of the flight plan).
The usefull data associated to the TO waypoint are displayed in the right upper corner. They are: waypoint identification (item be), bearing to go (item bf), distance to go (item bg), and estimated GMT at arrival at this waypoint (item bh).

All these data are displayed in green color and are cleared in case of failure.

J. Map Information - Optional Navaids

Navigation Display - PFD/ND Control

In addition, each pilot may select additional information which are called option: waypoints or navaids or airports which are in the zone presented on the ND, but which are not included in the flight plan, or constraint for given points.
Each option is selected by pressing the associated pushbutton switch on the FCU-EFIS control section. These options are exclusive, and the priority is given to the last one which has been selected.
The five P/B switches dedicated to the options are:

(1) ARPT
For airports, presented with a star symbol (in magenta color).

(2) NDB
For NDB navigation stations (triangle symbol in magenta).

(3) VOR-D
For VOR-D navigation stations: symbol, cross for VOR, circle plus cross for VOR-DME, and circle for DME alone (in magenta color).

(4) WPT
For waypoints not included in the flight plan symbol lozenge (in magenta color).

(5) CSTR
When the pilot presses the CSTR pushbutton switch on the FCU, the ND displays in magenta color the altitude, speed, time , possible constraints at waypoints of the flight plan. The altitude constraints may be MCA (minimum crossing altitude) at given fixes, or constrained altitudes at fixes in terminal areas and along final trajectory, or minimum holding altitudes. All the above constraints are written just below the concerned waypoint identification (maximum of 3 lines of 6 characters each). For example:
TOI
-6000
180 Kt.
21:30

(6) CSTR
When the pilot presses the CSTR pushbutton switch on the FCU, the ND displays in magenta color the altitude, speed, time and possible constraints at waypoints of the flight plan. Altitude constraints may be the Minimum Crossing Altitude at given fixes, constrained altitudes at fixes in terminal areas and along final trajectories, or minimum holding altitudes. All the above constraints are written just below the concerned waypoint identification (with a maximum of 3 lines of 9 characters each). For example:
TOI
-6000
180 Kt.
21:30

(7) MORA In addition a digital readout of the MORA is displayed in thousands of feet and in magenta in the lower left corner of the ND (item ar). It has priority over the offset path indication. It represents the Minimum Off Route Altitude allowed in a circle of 80 NM around the A/C.

Navigation Display - PLAN Mode ** ON A/C NOT FOR ALL

(8) Track and distance
In PLAN mode, the track and distance from the MAP reference point to the following FLIGHT PLAN waypoint are displayed below the MAP reference point identification.
As soon as CSTR option is selected on the FCU, the track and distance information is replaced by the constraint data.

K. PLAN Mode

Navigation Display - PLAN Mode ** ON A/C NOT FOR ALL

The ND displays a static map orientated with respect to the true North.
The displayed map information is the same as in ARC or ROSE-NAV mode but the map is centered on a map reference point. This point is chosen by the pilot on his MCDU and can be:

either the active waypoint
or any other selected waypoint of the flight plan.

The scale of the map is that chosen by means of the range selector (the range value selected corresponding to the diameter of the outer circle).
The GS, TAS and wind data, and the active waypoint data are displayed like in the other modes; but no navigation station characteristics and associated bearing pointers are available in this mode.
The A/C position on the map is represented by a true track-orientated yellow A/C symbol (item b).

L. Trafic Collision Avoidance System (TCAS)
The TCAS provides data for the display of intruders or specific messages through a high-speed ARINC 429 bus.

M. Trafic Collision Avoidance System (TCAS) - Display of Intruders

ND - TCAS Indications

Intruders are displayed on the NDs in ROSE or ARC mode only for 10, 20 or 40 NM selected ranges.
Intruders are displayed on the NDs in ROSE or ARC mode.
With the ABOVE/BELOW option of the TCAS, only the intruders located in a specified altitude area above or below the aircraft are displayed. This area is selected by means of the ABOVE/N/BELOW switch of the ATC/TCAS control unit.
(ABOVE : -2700 ft to +9900 ft max., N (normal) : +/- 2700 ft,BELOW : +2700 ft to -9900 ft max).

The traffic indications provide a view of the situation in the surveillance area. The aircraft present in this area are represented by symbols and associated tags. The position of the symbols on the display enables to determine the distance (range) and the bearing in the airspace. Both color and shape of the symbols are used to discriminate traffic according to the level of threat. The tags indicate relative altitude and vertical trend.
The various symbols used according to the type of intruder are presented below:

ND - TCAS Symbology ** ON A/C NOT FOR ALL

Other traffic for intruders with a range greater than 6NM or a vertical distance of at least +/- 1200 ft.

Proximate Traffic for intruders which do not enter in the Traffic Advisory (TA) or Resolution Advisory (RA) categories. Their range is within 6NM. Proximate traffic intruders and other traffic intuders can be displayed :

permanently if the FULL TIME DISPLAY function is selected on the ATC/TCAS control unit.
or
only when a RA or TA type intruder is detected

Resolution Advisory (RA)
.corrective : the pilot must modify present vertical speed
.preventive : the pilot must avoid certain vertical speed ranges.
Trajectory correction or holding visual orders are accompanied by synthesized voice announcements generated by the TCAS computer.

Traffic Advisory (TA) for intruders near the aircraft, which do not represent an immediate threat but may become a collision threat.
Off scale intruders are represented by a half-symbol displayed at the edge of the ND mask

W. Messages - ND 1(2 or 3) Switching Test
A switching test is performed on the ground from the MCDU to check that the digital link between the DMC and the DU is valid. The message : ND 1 (2 or 3 depending upon the the DMC linked to the DU) is displayed in magenta above the heading scale if the test is succesful.

X. Messages - Feedback Messages
A safety function is implemented in the DU to monitor the display of the critcal parameters (the heading, for example is a critical parameter). A feedback message is displayed as soon as a discrepancy occurs between what is sent by a sensor and what is actually displayed on the relevant DU.
The feedback messages are displayed on the left and right upper corners.

Z. Chrono indications

Navigation Display - Chrono Indication ** ON A/C NOT FOR ALL

Navigation Display - ROSE VOR Mode ** ON A/C NOT FOR ALL

The chrono indications are displayed on the left lower corner of the ND (item aq).
Each pilot can get a chrono indication (from the DMC internal clock) in any of the ND modes. The elapsed time information is indicated in digital form (green color), on a grey background colored area. The indication is given in minutes and seconds from O to 59' 59" or 9'59", then in hours and minutes from 1 h to 99h 59'.
When the pilot presses his onside CHRONO pushbutton switch, the chronometer display comes into view on his ND, and the chronometer starts counting.
When he presses this pushbutton switch again the chrono indication (elapsed time) freezes. When he presses it a 3rd time, the chrono is reset and the indication goes out of view.
In case of failure, all these indications are cleared.

Item aq: chrono indication
The chrono indication is given by the DMC internal clock

Navigation Display - ROSE VOR Mode ** ON A/C NOT FOR ALL

AA. Weather Radar

(1) Weather radar image

Navigation Display - Weather Radar Image ** ON A/C NOT FOR ALL

It is displayed when a WXR transceiver is operating (provided that there is information to be displayed, location of precipitation zones or geographic map contour), and provided that the ND is not in the PLAN mode. (The weather radar image can be obtained in all the other ND modes).
A weather radar picture can have elements of various colors: green, yellow, red, magenta, cyan, amber. The WXR transceivers generate 3 color bits to provide visual display of the intensity of atmospheric disturbances by varying the colors of the echoes. The colors change in the following order for increasing precipitation rates: black (not visible), green, yellow, red.

The magenta color is dedicated to severe turbulence areas, which are detectable up to 40 NM. If the range selection is above 40 NM (80 to 320 NM), then the transceiver will never send a magenta color code.
(COLLINS) :
When a very high intensity disturbance (storm) is detected at 80 NM distance or more, special indicating means are used in order to draw the pilot's attention on the fact that the image beyond the storm is not reliable because the gain can no longer be calibrated: a small radial yellow bar at the outermost range mark indicates that the storm cell ahead is attenuating the return signals from any disturbance located beyond this storm cell. The Path Attenuation correction mode is active.

In addition the weather radar image is superimposed to the map. (The active waypoint and its associated identification are displayed in a display window). For a given range selected value, the image scale is the same in the ROSE and ARC modes, since the ROSE diameter is exactly equal to the ARC radius in the ARC mode: the weather radar indications in the ROSE mode are identical to those in the ARC mode, but shifted upwards. (The same applies to the map data).

Navigation Display - Weather Radar Image ** ON A/C NOT FOR ALL

Consequently, the radius of the heading dial represents half the selected range marker value in the ROSE mode, and the full value in the ARC mode.

(2) Weather radar image

Navigation Display - Weather Radar Image ** ON A/C NOT FOR ALL

Navigation Display - Weather Radar Image in ARC Mode and ROSE NAV Mode ** ON A/C NOT FOR ALL

(7) WXR failure messages
Detected WXR failures are announced in the ND right bottom part, according to the following priority order:
R/T WR (red) for a WXR T/R failure (highest priority)
ANT WR (red) for a WXR antenna failure
CTL WR (red) for a WXR control unit failure
RNG WR (red) for an error in the range.

the DMC compares the range value from the FCU with the range sent back by the transceiver unit on its data bus. If there is a discrepancy, the weather radar is considered as faulty, and the echoes are no longer displayed.
However this comparison is inhibited for 8s after a change of selected range value, which is indicated on the ND by the RNG CHANGE message.
In case of multiple failures, only the highest priority message is written.
All the above failures lead to the cancellation of the WXR image.
Other failures not leading to a loss of the WXR image:
WEAK WR (amber) for a calibration failure

AB. GPWS TERRAIN Function (EGPWS)
The EGPWS (ENHANCED GROUND PROXIMITY WARNING SYSTEM) is built over the current GPWS. It includes a world wide terrain data base which allows to display the terrain hazards, in the selected range, on the ND and to generate warnings or caution when the predicted flight path of the A/C becomes unsafe with respect to the terrain. This function called "terrain awareness alerting and display" or "GPWS terrain function" is added to the GPWS functions.

(1) Terrain display on the ND

ND - TERRAIN Display ** ON A/C NOT FOR ALL

The terrain image is displayed when an EGPWS T/R unit is operating and there is some information to display, and provided that the ND is not in the PLAN mode. The EGPWS T/R unit is considered as operating when there is information on ARINC 453 bus.
A terrain picture may have elements of various colours: green, yellow, red, magenta, blue(cyan), amber.
The EGPWS T/R units generate 3 colour bits to provide visual display of terrain.

(a) Red warning area
The terrain areas associated with the warning criteria are displayed in solid red colour on the ND in mode: ARC, ROSE-NAV, ROSE-VOR or ROSE-ILS

(b) Yellow caution area
The terrain areas associated with the caution criteria are displayed in solid yellow colour on the ND in mode: ARC, ROSE-NAV, ROSE-VOR or ROSE-ILS

(c) Background terrain
When terrain data is available and sufficiently close to the A/C altitude they are displayed in background colour dot patterns. Different dot density patternss and colours are used to represent terrain altitude.
Areas with no terrain data available are painted with light density magenta.
Known terrain sufficiently below the A/C altitude is not painted (black).
Background terrain areas are shown on ND when ARC, ROSE-NAV, or ROSE-VOR, or ROSE-ILS mode is selected.

NOTE: The different colours are encoded by the EGPWS and sent to the DMC in such a way that all the colour change logics, altitude thresholds linked to the terrain image are computed by the EGPWS only, similarly to the WXR display.

(2) Terrain display on the ND

ND - TERRAIN Display ** ON A/C NOT FOR ALL

(a) Red warning area
The terrain areas associated with the warning criteria are displayed in solid red colour on the ND in mode: ARC, ROSE-NAV, ROSE-VOR or ROSE-ILS

(b) Yellow caution area
The terrain areas associated with the caution criteria are displayed in solid yellow colour on the ND in mode: ARC, ROSE-NAV, ROSE-VOR or ROSE-ILS

ND - TERRAIN Display ** ON A/C NOT FOR ALL

(3) Terrain display on the ND

ND - TERRAIN Display ** ON A/C NOT FOR ALL

The terrain image is displayed when an EGPWS T/R unit is operating and there is some information to display, and provided that the ND is not in the PLAN mode. The EGPWS T/R unit is considered as operating when there is information on ARINC 453 bus.
A terrain picture may have elements of various colours: green, yellow, red, magenta, blue(cyan), amber.
In case of a terrain warning or caution, the brightness of the terrain image is automatically set to a high setting if the brightness was below this setting.
The EGPWS T/R units generate 3 colour bits to provide visual display of terrain.

(a) Red warning area
The terrain areas associated with the warning criteria are displayed in solid red colour on the ND in mode: ARC, ROSE-NAV, ROSE-VOR or ROSE-ILS

(b) Yellow caution area
The terrain areas associated with the caution criteria are displayed in solid yellow colour on the ND in mode: ARC, ROSE-NAV, ROSE-VOR or ROSE-ILS

ND - TERRAIN Display ** ON A/C NOT FOR ALL

(4) EGPWS messages on the ND
TERR message
The message "TERR" or "TERR AHEAD" is displayed on the ND in lieue of the tilt angle value related to the weather radar (right lower corner) as soon as a terrain frame is detected as valid by the DMC in the ROSE-NAV mode, ROSE-VOR, ROSE-ILS, or ARC mode.
Both messages TILT and TERR or TERR AHEAD cannot overlay because the terrain frames and the WXR frames cannot be received at the same time by the DMC.
The message "TERR AHEAD" is displayed in red colour when some warning criteria is met. It is flashing for 9 seconds, then remains steady and red until the warning condition disappears.
The message "TERR AHEAD" is displayed in amber colour when caution criteria are met. It is flashing for 9 seconds, then remains steady and amber until the the caution condition disappears.
The message "TERR" is displayed in cyan colour otherwise.
A priority rule is established to display these messages since they are located at the same place on the ND screen, as follows:
TERR AHEAD in red (most priority)
TERR AHEAD in amber
TERR in cyan (less priority)
The message TERR RNG is displayed in red when there is an error in the range or when an FCU fault is detected by the EGPWS.
When the EGPWS is in test mode, a special pattern is displayed and if there is no failure, the amber message TERR TST is displayed.

(5) EGPWS messages on the ND
TERR message
The message "TERR" or "TERR AHEAD" is displayed on the ND in lieue of the tilt angle value related to the weather radar (right lower corner) as soon as a terrain frame is detected as valid by the DMC in the ROSE-NAV mode, ROSE-VOR, ROSE-ILS, or ARC mode.
Both tilt angle value and messages TERR or TERR AHEAD or TERRAIN or OBST AHEAD or OBST cannot overlay because the terrain frames and the WXR frames cannot be received at the same time by the DMC.
The message "TERR AHEAD" or TERRAIN or OBST AHEAD or OBST are displayed in red colour when some warning criteria is met. It is flashing for 9 seconds, then remains steady and red until the warning condition disappears.
The message "TERR AHEAD" or TERRAIN or OBST AHEAD or OBST are displayed in amber colour when caution criteria are met. It is flashing for 9 seconds, then remains steady and amber until the the caution condition disappears.

ND - TERRAIN Display ** ON A/C NOT FOR ALL

(7) Airport navigation display on the ND

ND - New EFIS Control Panel with the ZOOM Notch on the Range Selector ** ON A/C NOT FOR ALL

ND - Airport Navigation Display in ARC, ROSE NAV and PLAN Modes ** ON A/C NOT FOR ALL

ND - Runway Approaching Advisory Function in ARC, ROSE NAV and PLAN Modes ** ON A/C NOT FOR ALL

Airport navigation information is available when the ZOOM range is selected on the FCU in any of the ND mode except the ROSE VOR or the ROSE ILS mode. It provides an airport map through the video interface (optical fiber) from the Onboard Airport Navigation System (OANS) database.
The function is activated by setting the ND range selector on the ZOOM notch. The airport map is then displayed with a 5 NM range. Each time the flight crew turns the ND range selector counterclockwise, the range is decreased in the following order:

5 NM
2 NM
1 NM
0.5 NM
0.2 NM.

Turning the selector clockwise increases the ND range in the opposite order.
As soon as the flight crew selects a range different from the ZOOM range, the airport map is removed from the screen and the corresponding range value is used (example 10 NM).
Jointly to airport navigation display, the Runway Approaching Advisory function attracts the flight crew attention while approaching a runway on the ground.
On the ND, this function displays:

The selected ZOOM range
A pulsing message indicating the name of the runway in the middle part of the map in the ARC and the ROSE-NAV modes (the corresponding runway included in the airport navigation function symbology flashes to locate the advisory)
A pulsing RWY AHEAD : CHANGE MODE message in PLAN mode
A pulsing RWY AHEAD message in all the ND ranges (except the ROSE VOR or ROSE ILS mode) greater or equal to 10 NM.

AC. Image display stopping conditions

(1) ND PLAN mod is selected by the flight crew.

(2) Range discrepancy
The DMC compares the range value from the FCU with the range sent back by the WXR T/R unit or the EGPWS T/R unit on its data bus. If there is a discrepancy, the WXR or the EGPWS is considered as faulty and the WXR echoes or the terrain picture are no longer displayed. However this comparison is inhibited for 8s, after a new range selection, with this indication RANGE CHANGE displayed on the ND.

(3) WXR fault (refer to the label 055 definition) transmitter/receiver fault, antenna fault, control fault.

(4) No refresh.
The cause of no refresh can be
no label 055 or label 066 during 6s,
wrong data accept during 12s,
wrong control accept during 6s.
Before erasing the WXR or terrain picture, the DMC operates with the previous data during 6 or 12s depending on the above criteria.

(5) Switching between EGPWS and WXR
Ref to the SDAC label 007.01/28
The cause of the switching can be the change:

from the label 055 to 066
or from the label 066 to 055

NOTE: Upon such a switching the monitoring of the frame validity is re-initialized (the image is erased).

AD. Predictive Windshear Function

Navigation Display - Windshear Function ** ON A/C NOT FOR ALL

The location of the windshear event is identified by an icon superimposed on the WXR image shown on the ND. Three alert levels show the risk level of the event and distance from aircraft.
The two most important levels are identified by dedicated messages on the ND.
These messages show in red or amber color (for the alert level) in the middle of the ND screen:

W/S : CHANGE MODE shows on PLAN mode selection
W/S : SET RNG 10NM shows when the range is greater than 10NM
PRED W/S (Amber color) shows when a fault occurs without affecting the radar modes or detection function and when the A/C is on ground or when the flap/slat control lever is in a position different from 0 deg.

All the windshear messages do not show when the W/S AUTO/OFF switch is set to OFF or when the WXR system is defective.

In windshear mode, the message 'PWS SCAN' is displayed in the right upper corner of the ND.

A. ADIRU

Navigation Display - Interface with ADIRU (IRS/ADC)

(1) IRS
DMC1 receives the ADIRU 1 and 3 IRS buses.
DMC2 receives the ADIRU 2 and 3 IRS buses.
Normally, the DMC1 uses the data from ADIRU1 IRS.
In case of failure of the ADIRU1 , the CAPT can switch normally to the ADIRU3 IRS by setting the ATT/HDG selector switch to CAPT/3. The same applies for DMC2 normally using data from ADIRU IRS2, or from ADIRU IRS3 by setting the ATT/HDG selector switch to F/O/3.

(2) ADC
The ADIRU ADC bus selection inside the DMC follows exactly the same rules as the IRS bus selection. However the IRS and ADC manual reconfiguration selections are completely independent.

B. FMGC HS EFIS Bus

Navigation Display - Interface with FMGC

Each FMGC sends one HS EFIS output bus to the 3 DMCs. The DMCs which operate on side 1 work with FMGC1 data, and the DMCs which operate on side 2 use the FMGC 2 data. If one FMGC EFIS bus is no longer valid, the DMC(s) which normally use its data automatically switch over to the EFIS bus of the other FMGC, for instance DMC1 will work with FMGC2 EFIS bus. However, after the second engine start, or when the Captain changes ND mode to ARC or ROSE-NAV mode, or on the ground,if the FMGC1 EFIS bus is seen healthy for more than 3 s. The DMC1 will be forced on the FMGC1 EFIS bus. If the FMGC1 EFIS bus is still found invalid, the DMC1 will resume working with FMGC2 EFIS bus (the same applies to the DMC working on side 2, replacing in the text FMGC1 with FMGC2 and vice-versa, and Captain with F/O).
If the EFIS bus of the first FMGC is again valid, the DMC(s) revert to it. If the two FMGC EFIS buses are not valid, the DMC(s) permanently switches from one to the other until finding a valid one. Meanwhile, the amber message MAP NOT AVAIL is displayed on the ND. (If they are in ROSE-NAV or ARC or PLAN modes).

C. FCU

Navigation Display - Interface with FCU

The FCU is a dual unit fully redundant with 2 processors 1 and 2. Normally the processor 1 operates and the processor 2 is a hot spare. There are four outputs:

1.A which conveys CAPT selections plus some AFS selections
1.B which conveys F/O selections, the remaining AFS selections, both CAPT and F/O bars reference settings
and 2.A and 2.B buses which are exactly identical to 1.A and 1.B.

The DMC(s) on side 1 use the parameters from the buses 1.A and 1.B.
The DMC(s) on side 2 use the parameters from the buses 2.A and 2.B.
In case of failure of one bus there is an automatic switching from processor 1 to processor 2 inside the FCU.

I. Weather Radar

Navigation Display - Interface with Weather Radar ** ON A/C NOT FOR ALL

Each DMC receives from the transceiver unit its 2 data buses, D1 and D2. The DMC processes the information from the in service transceiver unit.
The DMCs which operate on side 1 normally work with the data 1 bus, which corresponds to the CAPT range selection. However, they can operate with a data 2 bus, i.e. using the data corresponding to the range selected by the F/O, in case of an FMGC1 failure which leads to an automatic change-over to the FMGC2 data in the DMC1. (SET OFFSIDE RANG/MODE message on the CAPT ND).

The same applies for the DMCs working on side 2, which normally use the D2 bus, but which use the D1 bus in case of FMGC2 failure.

5. Flags Test

Navigation Display - Flags Test Image ** ON A/C NOT FOR ALL

When performing a cockpit light test all the EIS DUs display fixed flags test patterns showing flags and annunciators at their proper locations.
This mode is inhibited in flight.
This test is activated by the DMCs on reception of a ground discrete signal coming through contacts of a relay. This relay is controlled by a signal coming from the ALTU (annunciator light test unit) in series with a flight/ground switch contact.
