APU Starter Limits
Cooling period between each starting attempt:
Between 3 Consecutive Attempts
1 MINUTE OFF
Between 2 Series of 3 Consecutive Attempts
30 MINUTES OFF
Engine Starter Limits
On Ground: Starting or Dry Motoring UP TO 5 MINUTES ON, 5 MINUTES OFF OR 1st to 4th Cycles 1 MINUTE ON, 1 MINUTE OFF Following Cycles 1 MINUTE ON, 5 MINUTES OFF In Flight: Maximum Continuous Operation Time 5 MINUTES ON
Max Oil Pressure below 88% N2
110 psi
(2) May be exceeded during starts if oil temp. is below 21ºC. The engine must remain at IDLE until the pressure is less than 110 psi.
(6) Operation in oil pressure amber range between 111 and 115 psi is permitted in all operational modes and time limited to 5 minutes, or between 116 and 155 psi in all operational modes time limited to 2 minutes. Total time above 110 psi may not exceed 5 minutes.
Max Oil Pressure above 88% N2
110 psi (6) Operation in oil pressure amber range between 111 and 115 psi is permitted in all operational modes and time limited to 5 minutes, or between 116 and 155 psi in all operational modes time limited to 2 minutes. Total time above 110 psi may not exceed 5 minutes.
Engine Warm up
Prior to take-off, the engines must be allowed to run at low thrust to stabilize the engine temperatures 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 more than 90 minutes) or 2 minutes for warm engines. To increase N2 above 83% the engine oil temperature must be at 40ºC minimum. In lieu of this limit, it is acceptable to either run the engine for at least 8 minutes or complete a static run-up to 88% N2, stabilize, and check to ensure that oil pressure is equal to or less than 83 psi.
