If the engine fire push light extinguishes after retarding the throttle to idle in flight (step 1 in boldface), what should the crew do?
Use master test switch on overhead panel to test fire detection system
If the test fails after the light goes out in flight, what next?
Assume fire, finish the continue the checklist
What does pressing the engine fire switch do?
Arms both fire bottles and cuts off generator to the GCU
During the engine start, the crew chief report flame in the tail pipe, at the same time you also get Engine Fire Push light, what procedure do you run?
Engine Fire during ground ops boldface
During engine fire on T/O, when should you secure the engine?
400 AGL and clear of obstructions
If engine failure is accompanied by loud bang, should you attempt restart?
No, potential for FIRE FOD or FROZEN
What warning should you remember when moving the throttle aft during EFC failure?
Avoid rapid movement of throttle because of potential compressor stall
with engine synch on, will the right engine roll back if the left engine fails?
Yes, but only up to 1.5%
How does EFC failure affect thrust and acceleration
loss of thrust, slower acceleration
with EFC off, ensure throttle is below what position before turning EFC back on?
Normal T/O
If you have engine failure during ACM off T/O, leave ACM off until what altitude?
