Engine Notes List

Question 0

Engine cool down:

Answer 0

The engines must run for at least 1 minute at idle or taxi thrust before shut down.

Question 1

Engine warm up:

Answer 1

Prior to take off, the engines must be allowed to run at low thrust to stabilize the engine temps before take off thrust is adjusted. After start, the engines must run at idle or taxi thrust during at least 4 minutes for cold engines (shut down for mor than 90 min) or 2 min for warm engines. To increase N2 above 83% the engine oil temp must be at 40C minimum. In lieu of this limit, it is acceptable to either run the engine for at least 8 min or complete a static run up to 88% N2, stabilize, and check to ensure that oil pressure is equal to or less than 83PSI.
