4. Procedure
Subtask 34-36-00-720-060-A ** ON A/C NOT FOR ALL

A. ILS Reception Test

ACTION	RESULT
1.On the circuit breaker panel 49VU (121VU):	On the CAPT (F/O) PFD and the F/O (CAPT) ND:
Close the circuit breaker 42RT1 (42RT2).	The G/S, LOC and ILS flags go out of view.
2.On the RMP1 (RMP2):	On the RMP1 (RMP2):
Push the NAV pushbutton switch.	The green LED on the NAV pushbutton switch comes on.
Set the frequency related to the signal given by the ground test unit ILS - Frequency and Course Selection ** ON A/C NOT FOR ALL	The set frequency comes into view in the left display.
3.On the ground test unit:	On the CAPT (F/O) PFD:
Set the LOC and G/S selector switches to 0.	The G/S and LOC indexes come into view in the middle of the scale. On the F/O (CAPT) ND: The G/S index and the LOC deviation bar come into view in the middle of the scale.
Set the G/S selector switch to up 1 point then up 2 points.	On the CAPT (F/O) PFD and F/O (CAPT) ND: The G/S index moves up 1 point then up 2 points.
Set the G/S selector switch to down 1 point then down 2 points.	The G/S index moves down 1 point then down 2 points.
Set the G/S selector switch to 0.	The G/S index moves to the middle of the scale.
Set the LOC selector switch to left 1 point then left 2 points.	The LOC index and deviation bar move 1 point then 2 points to the left side.
Set the LOC selector switch to right 1 point then right 2 points.	The LOC index and deviation bar move 1 point then 2 points to the right side.
Set the LOC selector switch to 0.	The LOC index and deviation bar move to the middle of the scale.
4.On the RMP1 (RMP2):
Set the CRS related to the aircraft heading +20°, then to the aircraft heading -20°.	On the F/O (CAPT) ND: The aircraft heading +20°, then the aircraft heading -20° come into view in the right upper corner. The course pointer moves to the aircraft heading +20°, then to the aircraft heading -20°.
5.On the circuit breaker panel 121VU (49VU): Close the circuit breaker 42RT2 (42RT1).

Subtask 34-36-00-720-061-A ** ON A/C NOT FOR ALL

B. ILS Identification Test

ACTION	RESULT
1.On the circuit breaker panel 49VU (121VU), close the circuit breaker 42RT1 (42RT2).
2.On the ground test unit, set the IDENT selector switch to ON.
3.On the center pedestal, on one ACP:
Release the LS pushbutton switch.	You can hear the identification signal in the loud speakers.
Turn slowly the LS pushbutton switch until the volume is correct.

5. Close-up
Subtask 34-36-00-080-055-A ** ON A/C NOT FOR ALL

A. De-energize the VOR/ILS ground test unit and remove it.

Subtask 34-36-00-860-089-A ** ON A/C NOT FOR ALL

B. Put the aircraft back to its initial configuration.
(1) On the CAPT and F/O EFIS control sections of the FCU, release the ILS pushbutton switches.
(2) Do the EIS stop procedure (Ref. AMM TASK 31-60-00-860-002).
(3) On the center pedestal, on the RMP1 (RMP2):

push the NAV pushbutton switch (the green LED goes off).
set the ON/OFF switch to OFF.

(4) On the ADIRS CDU, set the OFF/NAV/ATT selector switches to OFF.
(5) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
(6) Make sure that the work area is clean and clear of tools and other items.
