Engine Start Procedures
NOTE: After the GTS start button is released, the
ignition ON period is automatically started by a logic
circuit in the ECA and terminated by a signal from
the start control unit when N2 accelerates through
45% RPM or after 45 seconds when ignition is
terminated and GTS returns to IDLE. ECA monitors
N1 RPM. When N1 shaft speed reaches 100 RPM in
correct direction of rotation, ECA signal is sent to
illuminate READY advisory light and fire engine

(1) OFF: interrupts or prevents fuel flow to
engine
(2) IDLE: opens fuel shutoff valve to direct fuel
to fuel spray nozzles
(3) APPROACH IDLE: with landing gear down
and aircraft weight off wheels, maintains
