| 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 |
