ENGINE OPERATING LIMITS
Takeoff thrust settings that are nominally limited to 5 minutes duration may be used for up to 10 minutes for One Engine Inoperative operations.
The engine should not be operated above 80% N2 until oil temperature is above 10°C (+50°F).
Abort the start if N1 does not indicate rotation before 25% N2, or if the engine stops accelerating for 30 seconds.

If engine oil temperature is below -40°C (-40°F), what must come first?
The engine must be preheated prior to conducting a start
If the battery has been cold soaked for 2 hours or longer at ambient surface temperature of -18°C (0°F) or lower, what must come first?
It must be preheated to above -18°C (0°F) prior to start.
How long to get the Engine Indicating System to work when the aircraft is cold soaked below -10°C (+14°F).
1 to 6 minutes
STARTER CYCLE LIMITATIONS
Three engine starts per 30 minutes. Three cycles of operation with a 60-second rest period between cycles is permitted.
BATTERY LIMITATIONS
- The battery temperature warning system must be operational for all ground and flight operations.
- Battery Cycle Limitations: Three engine starts per hour.
- Three generator assisted cross starts are equal to one battery start.
- If an external power unit is used for start, no battery cycle is counted.
Maximum Generator Current (per generator) (ground)
200 Amperes
How long to limit ground operation of pitot/static heat to preclude damage to the pitot tubes and angle of attack vane.
2 Minutes
Ground operation at greater than 75% N2 engine RPM with engine, wing, and/or windshield anti-ice on is limited to how long?
2 minutes. Do not operate with the wing anti-ice on more than one minute after the WING ANTI-ICE L/R annunciators have extinguished.
Where must the temperature be obtained during ground operations?
Ambient surface temperature must be obtained from the RAT display at the bottom of each PFD, with either or both engines operating, or from an appropriate ground station. The SAT display is unreliable on the ground.
FUEL LIMITATIONS - When must the fuel pumps be on?
Fuel Boost Pumps – ON; when FUEL LOW LEVEL L and/or R caution lights illuminate or at 210 pounds or less indicated fuel.
Fuel imbalance
Maximum approved fuel imbalance is 200 lbs. A fuel imbalance of 600 lbs. has been demonstrated for emergency return.
Fuel additives
EGME/DIEGME additive is approved for use, but not required, at a concentration not to exceed 0.15 percent volume.
UNUSABLE FUEL LIMITATIONS
Fuel remaining in the fuel tanks when the fuel quantity indicator reads zero is not usable in flight
