ENGINE WARM-UP
Prior to takeoff, the engines must be allowed to run at low thrust to
stabilize the engine temperatures before takeoff thrust is selected.
After start, the engines must run at idle or taxi thrust for at least
4 minutes for cold engines or 2 minutes for warm engines.
Before takeoff, to increase N2 above 83% the engine oil temperature
must be at 40°C minimum. In lieu of this limit, it is acceptable to either:
- run the engine for at least 8 minutes in idle or taxi thrust and check if
the temperature is at least 21°C or,
- for airplanes Pre-Mod. Rolls-Royce SB AE3007A-79-025, complete a
static run-up to 88% N2, stabilize, and check to ensure that oil
pressure is equal to or less than 83 psi.
NOTE: The engine is considered cold if it has been shutdown for more
than 90 minutes.
ENGINE COOL DOWN
The engines must run for at least 1 minute at idle or taxi thrust before
s
hutdown.
