A. Preparation for Test

NOTE: When an engine ground run is carried out, it is necessary to enter a new flight number through the MCDU (at least one dummy character is sufficient) to get a new PFR.

(1) Obey the wind limitations and safety precautions during engine ground operations (Ref. AMM TASK 71-00-00-869-802) and (Ref. AMM TASK 71-00-00-869-803).
(2) Put chocks in position in front of each forward outboard MLG wheel.

NOTE: If engine start is followed by a high power run, use 98F10103500000 CHOCK-MLG,ENGINE RUN-UP.

Tool Installation

(3) Make sure that the engine inlet and exhaust covers are removed. Make sure that these areas are clear of unwanted objects.
(4) Make a visual check of the temperature sensors, fan inlet and exhaust areas. If snow or ice has collected in the fan duct, make sure that the fan turns freely. Also, make sure that the engine inlet, inlet lip, fan, spinner and fan exhaust duct are clear of ice or snow. If the fan does not turn freely, melt the ice or snow with hot air before an engine operation.
(5) If it is necessary, deice or anti-ice the fan blades. Refer to task Engine Start In Cold Weather Conditions (Ref. AMM TASK 12-31-71-660-803).
(6) Look at the general condition of the fan spinner and fan blades, core exhaust nozzle, LPT and external surfaces of the cowls.
(7) Make a check of the drain ports for fuel, oil and hydraulic leaks (Ref. AMM TASK 71-00-00-790-805).

NOTE: In case of extreme cold weather condition (OAT < -20 deg.C), fuel leaks from the drain may occur and should not be considered as abnormal. Therefore, check for fuel leaks at the drain mast shall be performed with the engine fully stabilized at idle.

(8) Remove covers from TAT, AOA and PITOT probes.

(b) Make sure that the pressure of the Green reservoir for the engine 1 or/and the Yellow reservoir for the engine 2 is correct.
(c) Make sure that the reservoir fluid level is correct.
(4) Make sure that the engine 1(2) pump is serviceable:
(a) On the ENG panel 40VU, the OFF legend of the ENG 1(2) PUMP pushbutton switch must be off.

Subtask 71-00-00-710-279-A

F. Do the operational test of the engine fire and overheat detection (loop/squib) (Ref. AMM TASK 26-12-00-710-001).

Subtask 71-00-00-869-396-A

G. Continue to prepare for test
(1) On the RUD TRIM/PARKING BRK panel 110VU:
(a) Make sure that the parking-brake control switch is set to ON.
(2) On the ENG panel 115VU:
(a) Make sure that the ENG/MASTER 1(2) control switch is set to OFF.
(3) Make sure that the throttle control lever of the engine 1(2) is in the idle stop position (zero on the graduated sector).
(4) On the center instrument panel 400VU, make sure that:
(a) The brake pressure indication on the brake yellow-pressure triple-indicator is correct. If necessary, pressurize the brake accumulator with yellow pump (Ref. AMM TASK 29-10-00-863-002).
(b) The landing-gear normal control-lever is in the DOWN position.
(5) Make sure that the interphone system operates correctly.
(6) Make sure that the aircraft is cleared and that no one stays in the dangerous areas.
(7) On the lower ECAM display unit:
(a) Get the FUEL page. Make sure that there is the correct quantity of fuel in the fuel tanks to run the engine.
(8) On the ENG panel 40VU:
(a) If there is fuel in the center tank, make sure that MODE SEL is in AUTO (the MAN legend off).
(b) Push all the FUEL/PUMPS pushbutton switches (the OFF legends of these pushbutton switches go off).
(9) Supply the aircraft pneumatic system from a HP ground power unit or the APU (Ref. AMM TASK 36-12-00-860-805) or (Ref. AMM TASK 36-12-00-860-806).

NOTE: The minimum recommended starter air supply pressure is 25 PSI, when the start valve is open.
Two external pneumatic power units may be used in parallel, if the pressure/flow relation is expected to be marginal.

(10) On the overhead CTL & PNL panel 25VU:
(a) Set the EXT LT/BEACON switch to ON.

CAUTION: IN ICING CONDITIONS, DO NOT OPERATE THE ENGINE AT GROUND IDLE FOR MORE THAN 120 MINUTES. LONG GROUND IDLE OPERATION IN ICING CONDITIONS CAN CAUSE THE FORMATION OF ICE. ICE CAN CAUSE INCREASED FAN VIBRATION.

(11) If you operate the engine at ground idle and in icing conditions for over 120 minutes or if ENG X HIGH VIBRATION message appears while you operate the engine in these conditions, increase engine speed to 45 percent N1 for 5 seconds and return to idle. Do this procedure again as necessary to reduce fan vibration or at 60 minute intervals while you operate the engine at ground idle.

4. Procedure
Subtask 71-00-00-710-278-A

WARNING: AFTER AN ABORT OF THE ENGINE STARTING SEQUENCE, A DRY CRANK, TO REMOVE FUEL VAPOURS, WILL OCCUR, ACCOMPANIED BY ECAM MESSAGE:

AUTO CRANK IN PROGRESS

ON COMPLETION OF THE DRY CRANK, ALWAYS PUT THE "ENG/MASTER" SWITCH BACK TO THE "OFF" POSITION WHEN INSTRUCTED BY ECAM MESSAGE:

ENG MASTER OFF.

IF YOU ONLY CHANGE THE POSITION OF THE ENGINE MODE SELECTOR SWITCH (FROM "IGN/START" TO "NORM"), THE FADEC SYSTEM WILL NOT COMPLETE THE ABORT. THERE IS THUS A RISK THAT THE ENGINE WILL START. THIS CAN CAUSE INJURIES TO PERSONS.

WARNING: SET THE THRUST LEVERS TO IDLE BEFORE YOU START THE ENGINE. IF YOU DO NOT DO THIS, THE THRUST LEVEL WILL RAPIDLY INCREASE AND CAN CAUSE DANGEROUS CONDITIONS.

CAUTION: DO NOT OPERATE THE ENGINE IF THE FUEL INLET PRESSURE IS NOT POSITIVE. THE FUEL IS NECESSARY TO LUBRICATE THE ENGINE FUEL PUMP AND THE HMU AND THUS PREVENT DAMAGE.

CAUTION: MONITOR THE START CYCLE VERY CAREFULLY WHEN THE STARTER AIR INLET PRESSURE IS LOWER THAN RECOMMENDED (SPECIAL OPERATION CONDITIONS). THIS CAN CAUSE LONGER TIMES TO GO TO IDLE AND HIGHER EGT PEAKS.

A. Do this test:

ACTION	RESULT
1.On the ENG panel 115VU: Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to IGN/START. NOTE: Engine alerts and warnings should be cleared prior to starting.	On the lower ECAM display unit: The ENGINE page comes into view. Make sure that: The recommended minimum starter air pressure with the start valve open after initiating the start is 25 psi (1.7237 bar). The oil quantity is correct. If necessary, fill the oil tank (Ref. AMM TASK 12-13-79-610-805). NOTE: The oil level in the oil tank can go down by 7 l (1.8492 USgal) during start.
2.On the ENG panel 115VU: Set the ENG/MASTER 1(2) control switch to ON. On the upper ECAM display unit: Monitor the important parameters N1, N2, EGT, FF. On the lower ECAM display unit: Monitor the oil pressure.	On the lower ECAM display unit, on the ENGINE page: The symbol for the starter valve opens. Above 20 percent N2, when the automatic dry cranking is completed, the A or B indication comes into view below IGN. At 55 percent N2: IGN OFF. At 63 percent N2: The symbol for the starter valve is in the closed position.
NOTE: In the automatic mode, the EEC provides automatic sequencing of the starter, ignition and fuel. Depending on the engine thermal state, the FADEC can command an automatic dry cranking before the start of the engine. The dry cranking may last up to approximately one minute. During the dry cranking, the FADEC logic limits the maximum N2 to 30 percent. During the dry cranking, the vibration level increases but remains below the amber display limit in normal operating conditions. The EEC will authorized ignition only when the automatic dry cranking is completed. After completion of pre-start motoring, the normal ground autostart procedure will proceed. Light-off will normally occur within 2 to 3 seconds after the fuel metering valve opens. During motoring (after master lever has been turned on), there is a manifold prefill function that will open the FMV to pre-fill the fuel manifold. This commonly lasts less than 10 seconds, but is allowed to take up to 30 seconds. Lightoff will not be attempted during pre-fill. Cold temperature conditions may extend time to light-off. In the automatic mode the EEC will close the fuel metering valve if light-off is not attained within 15 seconds, the engine will automatically dry motor for 30 seconds, then perform two additional.	NOTE: When the pack valves start to close the FAULT legend of the AIR/COND PACK1/2 pushbutton switches on the AIR COND panel 30VU come on until the pack valves are fully closed. NOTE: The engine operates at a stabilized ground idle only when there is a positive oil pressure indication.
	NOTE: Positive oil pressure must be indicated by the time the engine reaches idle. Stabilized pressure below 17 psi minimum requires immediate shutdown. During cold weather operations, oil pressure peaks to full scale may occur due to high oil viscosity. Pressure should decrease as oil temperature increases. In all cases, if the oil pressure remains above the normal range after the oil temperature has stabilized within limits, the engine should be shut down and the cause investigated.
	If this occurs, on the ENG panel 115VU: Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to NORM. Set the ENG/MASTER 1(2) switch to OFF. After the starter is cool, the operator must make a decision: try another auto or manual start or stop and correct the problem.
3.When the engine idle speed is stable, on the ENG panel 115VU: Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to NORM. NOTE: It is recommended that the engine operates at or near idle for a minimum of 3 minutes before you increase to high power. You must move the throttle control lever slowly, carefully and smoothly when possible. NOTE: You can use taxi time at or near idle as part of the 3 minutes warm-up time.
