If an abortive start (hung start) occurs when starting a gas turbine engine, the correct action is to:
  • A
    select the other igniter system.
  • B
    move the thrust lever forward to increase fuel flow.
  • C
    shut down the engine.
  • D
    activate both igniter systems.
A hung start will result in N2 speed stabilizing at a lower than normal rpm and a subsequent increase in EGT. The engine fails to accelerate sufficiently because of a too low pneumatic starter pressure before the fuel is supplied to sustain combustion. Upon recognition of the hung start conditions, the flight crew needs to shut down the engine, conduct a cranking and initiate a cooling sequence before attempting a new engine start.
