Capt. Mike: Here's that evening's Captain's Challenge. Tap your answer.
After a long idle descent, a pilot moves a turbofan's thrust lever abruptly to take-off thrust. The rapid acceleration makes the engine most susceptible to:
The answer
2A compressor stall, or surge
Explanation
Fuel added faster than the compressor can accelerate raises combustor pressure and drives the compressor blades toward excessive angle of attack, which can produce a compressor stall or surge. Fuel controls (and FADEC acceleration schedules) limit the rate of acceleration for this reason, and thrust levers should be advanced smoothly.
Memory tip: Slam the thrust lever → risk of compressor stall. Advance it smoothly.
