Landing weight is limited by the most restrictive of the following requirements:
Max Certified Landing Weight 9700 Pounds
Max Landing Weight Permitted by Climb Requirements….Performance Section IV
Landing Distance… Performance Section IV
Maximum ITT for Idle
620 Max
N2% Turbine RPM 56.2 +/- 1.3 @ Idle
Maximum ITT for Takeoff
820 Max (5 minutes)
- 3 N2%
- 4 N1%
Maximum Continuous ITT
796 Max
- 3 N2%
- 4 N1%
Takeoff Thrust Limit
10 minutes for engine life to TBO
Refer to Performance 4-8
Performance data, including Vmca and Vmcg in Section IV is based on use of takeoff thrust.
Minimum Oil Pressure
Above 80% N2
45 PSIG
Below 80% N2
35 PSIG
Engine should not be operated above ________ % N2 until oil temperature is above ______ ^ C.
Engine should not be operated above 80 % N2 until oil temperature is above 10 ^ C.
Maximum Tailwind Component for Start
10 knots
Maximum Crosswind Component for Start
12 Knots
Thrust attenuator must be in AUTO mode for start with:
Tailwind within +/- 30 degrees.
Start downwind engine first
Maximum time to light off
10 seconds
Note: Time to light off is defined as the time the throttle lever is moved from off to idle position until light off is indicated.
Minimum Ambient Temperature for Battery Start
-30 degrees C
Maximum Temperature for Engine Start
ISA + 39 degrees C
Maximum Airport Elevation for Ground Battery Start
10,000 Feet
Maximum Airport Elevation for Ground External Power Start
14,000 Feet
Minimum Battery Voltage for Battery Start
24 VDC
Minimum / Maximum External Power Current Capacity for Start
800/1100 Amps
Note: normal starter current draw is approximately 1000 Amps peak. External power units with variable maximum current shut off should be set to 1100 Amps. Use of an external power source with voltage in excess of 29 V DC or current an excess of 1100 Amps can damage the starter.
What are the limitations regarding use of IGNITION during engine power reduction high-altitude
L and R IGNITION must be selected ON prior to reducing power to less than 90% N2 at or above FL 350. Ignition may be returned to NORMAL after engines have stabilized at the reduced power setting.
Starter Cycle Limitations
Three engine starts per 30 mins
Three cycles of operation with a 60 second rest period between cycles is permitted.
