25
Q

Max Oil Pressure below 88% N2

A

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.

26
Q

Max Oil Pressure above 88% N2

A 
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.
27
Q

Engine Warm up

A

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.

28
Q

Engine Cool-down Period

A

1 minute

29
Q

Min and Max Temperatures for A/I Operation

A

32
Q

Max Load on APU Gen

A

300 Amps above 30000 ft

33
Q

Max Alt Flap Extension

A

20000 ft

34
Q

Maximum Airspeed after Take-off/During Climb without Re-trimming

A

160 KIAS

35
Q

Maximum duration of ISIS when operating on batteries

A

40 minutes
Note: The maximum duration of battery power can be extended to 45 minutes if the Pitot 3 Sensor Heating Button is turned off when not operating in icing conditions. Airplane must not be moved during power-up initialization. Do not cage attitude in turning flight.
