GENERAL
The engine starting system consists of an air turbine starter and a start valve.
The start valve admits air supplied by the pneumatic system to operate the starter.
The FADEC controls the start valve electrically. If electrical control fails when the aircraft
is on the ground, a handle allows the start valve to be operated manually.
AUTOMATIC STARTING
This sequence is under the full authority of the FADEC, which controls :
- the start valve
- the igniters
- the fuel HP valves
The FADEC :
- detects a hot start, a hung start, a stall, or no light up
- announces FAULT and identifies the fault in an ECAM message
- runs an abort sequence if a start aborts on the ground
~ closes the HP valve
~ closes the start valve
~ turns off ignition
~ cranks the engine crank after the start abort in order to clear out fuel vapors
~ controls any additional start attemps.
For an inflight start, the FADEC decides whether the engine is windmilling fast enough or
needs assistance from the starter in view of current engine parameters and flight
environment parameters.
Flight crew may interrupt this start sequence by moving the MASTER switch to OFE
