fire warning test fails, or fire conditions persist:
Correct Answer:THROTTLE - IDLE (If conditions persist:) THROTTLE - CUTOFF ENGINE FIRE SWITCH - PUSH BOTTLE ARMED SWITCH - PUSH
Smoke Or Fumes In Aircraft
Correct Answer:OXYGEN MASKS - DON / 100%
Pitch Trim/Roll Trim/Rudder Trim Runaway
Correct Answer:TRIM INT & A/P DISENGAGE SWITCH - PUSH AND HOLD
Low Cabin Pressure
Correct Answer:OXYGEN MASKS - DON / 100%

Notes:

(1) Time limit starts when throttles first advanced for takeoff thrust.

(2) Normal Flight: Normal oil pressure is 60 to 83 PSI at N₂ speeds above 60 %. Oil pressure below 60 PSI is undesirable and should be tolerated only for the safe recovery of the flight, preferably at reduced power setting. Oil pressure below 40 PSI is unsafe.

(3) Under cold starting conditions, oil pressure between 83 PSI and 95 PSI is limited to 90 seconds.

(4) The ITT during ground starts should normally not exceed 550 °C.

Normal hydraulic pressure 1350 to 1550 PSI
Normal nitrogen pressure 1350 to 1650 PSI
Normal oxygen pressure 1600 to 1850 PSI
Min battery voltage for battery start 22 volts
Max gen load prior to starting second engine 150 amps
Motoring of the starter is limited to:
First, 30 seconds then 5 minutes cooling.
Second, 30 seconds then 15 minutes cooling.
Third, 30 seconds then 60 minutes cooling.

Do not use autopilot below FT AGL
Except for preflight checks and landing rollout, do not operate anti-ice systems during ground operations at temperatures above 10 °C OAT/SAT.
Do not operate surface anti-ice systems in flight at ram air temperatures above 10 °C.
To ensure proper wing anti-ice operation, the throttles must be kept at 70 % N2 minimum.
