1. Reason for the Job
Use this procedure to start the engine automatically.
NOTE: During a motoring sequence on the ground, the Electronic Engine Control (EEC) automatically determines if motoring to start is required for BOWED ROTOR PROTECTION. The EEC keeps the N2 speed at a low value (approximately 10% N2) for a calculated duration based on time since shutdown, Outside Air Temperature (OAT) and engine turbine temperature. During motoring to start, a "COOLING" indication is displayed on the upper ECAM display unit. When the motoring to start period is complete, the EEC will continue to normal engine start. If N2 exceeds the maximum speed for BOWED ROTOR PROTECTION during motoring to start, the EEC will abort the motoring and the warning ENG X START FAULT (BOWED ROTOR PROTECTION) will be displayed.

   (2) During the start, keep the service air bleed inputs and the accessory loads to a minimum.
CAUTION: REVERSE WINDMILLING CAN OCCUR IF THE AIRCRAFT IS OPEN TO A STRONG TAIL WIND. CAREFULLY MONITOR THE START TO PREVENT A HOT START. REFER TO WIND DIRECTION AND VELOCITY OPERATIONAL LIMITATIONS DIAGRAM.
   (3) If a tail wind prevents an easy start, move the aircraft toward the wind. Obey the wind direction and velocity operational limits (Ref. AMM TASK 71-00-00-910-804).
Subtask 71-00-00-860-208-A ** ON A/C NOT FOR ALL
WARNING: ALWAYS PUT THE ENG/MASTER SWITCH BACK IN THE "OFF" POSITION AFTER AN ABORT OF THE START SEQUENCE. IF YOU ONLY CHANGE THE POSITION OF THE ENG/MODE SWITCH (FROM "IGN/START" TO "NORM"), THE FADEC SYSTEM WILL NOT COMPLETE THE ABORT. IF YOU DO NOT OBEY THIS INSTRUCTION, THE ENGINE CAN START AND 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: ALWAYS PUT THE ENG/MASTER SWITCH BACK IN THE "OFF" POSITION BEFORE YOU START THE ENGINE. IF YOU DO NOT OBEY THIS INSTRUCTION, A HOT OR HUNG START CAN BE THE RESULT.
CAUTION: YOU MUST DO ALL OF THE STEPS IN THE START PROCEDURE THAT FOLLOWS IN THE CORRECT SEQUENCE. IF YOU DO NOT OBEY THIS INSTRUCTION, A HOT OR HUNG START CAN BE THE RESULT.
CAUTION: BEFORE YOU START THE ENGINE RUN OPERATIONS, MAKE SURE THAT ALL PYLON PANELS INCLUDED IN THE THRUST-REVERSER FIRE-SEAL LANDING ARE INSTALLED. IF ALL PYLON PANELS ARE NOT INSTALLED, THE THRUST-REVERSER FIRE SEAL WILL NOT OPERATE CORRECTLY.
B. Do the engine start as follows:
ACTION
RESULT
1.On the center pedestal, on ENG panel 115VU:
  • Set the ENG/MODE selector switch to IGN/START.
On the lower ECAM display unit:
  • The ENGINE page comes into view.
    . Make sure that the starter air supply pressure is available.
NOTE: The engine alerts and the warnings should be cleared prior to starting.
2.On the center pedestal, on ENG panel 115VU:
  • Set the ENG MASTER 1(2) control switch (for engine to be started) to ON.
Make sure that:
  • The symbol for the starter valve opens.
  • Do not set the ENG MASTER 1(2) control switch to ON before all the amber crosses and the messages have disappeared on the upper ECAM display unit.
3.Monitor the lower and the upper ECAM display units during the start for the usual engine parameters.
  • Make sure that N2 increases.
  • Make sure the related start valve in line on the ECAM lower display valve (Ref. AMM TASK 80-11-00-040-803).
    . You can then continue the auto start procedure.
  • Make sure that the bleed pressure indication is green on the ECAM lower display.
  • Make sure that the engine oil pressure increases.
  • At 18% N2, make sure the active igniter (A or B) indication comes into view adjacent to IGN on the ECAM lower display.
NOTE: The activation speed varies with the ambient temperature and the start air supply pressure.
  • The Fuel Flow (FF) increases.
NOTE: The normal starting FF for the PW1100G-JM series engine is approximately 200 Pounds Per Hour (PPH) or 91 Kilograms Per Hour (KPH) at all field elevations. Once the normal idle is achieved, a FF of approximately 500 PPH (227 KPH) is acceptable.
  • Within 20 seconds of the FF increase:
    . The Exhaust Gas Temperature (EGT) increases on the ECAM upper display.
    . N1 increases prior to 48% N2 on the ECAM upper display.
  • At approximately 55% N2:
    . The start valve cross line indicates valve closed on the ECAM lower display.
    . The active igniter indication off on the ECAM lower display.
4.Set the ECAM displays to CHECK.
  • Make sure that the main and the secondary engine idle parameters are normal.
NOTE: The gray background on N2 indication disappears.
  • The usual parameters at International Standard Atmosphere (ISA) sea level are as follows:
    . The EGT is in the range between 914 deg.F (490.00 deg.C) and 1130 deg.F (610.00 deg.C) approximately.
    . FF is approximately 600 PPH (270 KPH).
    . N1 is approximately 19%.
    . N2 is approximately 59%.
5.On ENG panel 115VU:
  • Set the ENG/MODE selector switch to NORM.
  • You must set the ENG/MODE selector switch to NORM after the two engines are started or after one engine is started if the second engine will not be started.
Subtask 71-00-00-860-216-A ** ON A/C NOT FOR ALL
C. Unusual Condition to Stop the Start Procedure:
   (1) On the Upper ECAM display, monitor the engine start and engine parameters for any unusual conditions.
     (a) Monitor the engine start for no light condition, no EGT increase or N2 and N1 acceleration beyond the N2 and N1 at the starter maximum speed. The EEC will automatically do an engine start abort.
     (b) Monitor the engine for slow N2 acceleration which is an indication of a possible hot or hung start. If this slow N2 indication also has a fast increase in EGT, and is near the start EGT limit, the EEC will automatically do an engine start abort.
     (c) If the EGT is near the start EGT limit, the EEC will automatically do an engine start abort (Ref. AMM TASK 71-00-00-860-814) and (Ref. AMM TASK 71-00-00-860-817).
     (d) If the EGT limits were exceeded, (Ref. AMM TASK 72-00-00-200-809).
NOTE: Record how much time the EGT was more than the limit and the highest temperature for subsequent analysis.
   (2) The EEC will automatically abort the start if the engine parameters are out of limits.
   (3) During an aborted start, the EEC will automatically engage the starter at the necessary N2 rotor speed to dry-motor the engine for 30 seconds to decrease the EGT and to remove the remaining fuel from the engine that has not burned for the conditions that follow:
     (a) If there is no EGT increase (no light or combustion).
     (b) If there is no acceleration (hung start).
     (c) If there is high EGT during the start (hot start).
   (4) During an aborted start, the EEC will not automatically engage the starter if any of the events that follow occur:
     (a) N1 locked rotor. No indication of sensed N1 after sensed N2 has increased beyond 30 percent.
     (b) Loss of EGT indication.
     (c) Inability to control fuel flow.
     (d) EEC is unable to command the igniters in either EEC channel.
     (e) Failure of automatic restart or unsuccessful restart.
   (5) When the engine reaches idle speed and is stable, do a check the upper and lower ECAM display as follows.
     (a) Make sure that N1, N2, EGT and fuel flow are at the usual idle values.
     (b) Make sure the engine oil pressure is the usual idle value.
     (c) Shutdown the engine if the oil pressure is below the amber line.
NOTE: The engine should be warmed up so that the oil temperature is at or above 18 deg.F (-7.78 deg.C) prior to any operation above idle. This is to ensure adequate engine oil scavenge capability.
   (6) In case of EGT overtemperature, operate the engine after an EGT overtemperature (Ref. AMM TASK 71-00-00-860-818).
   (7) In case of engine surge or stall, operate the engine after an engine surge or stall (Ref. AMM TASK 71-00-00-860-819).
   (8) In case of EGT overtemperature with surge or stall, operate the engine after EGT overtemperature with surge or stall (Ref. AMM TASK 71-00-00-860-820).
