AIR CONDITIONING
With either one or both engine BLEED air switches ON, do not operate air conditioning PACKS in HIGH for takeoff, approach or landing.
ENGINE ANTI-ICE
The engine anti-ice system must be ON during all ground and flight operations when icing conditions exist or are anticipated, except during climb and cruise below -40°C SAT.
Engine anti-ice must be ON prior to and during descent in all icing conditions, including temperatures below -40°C SAT.
AUTOPILOT
Do not engage the autopilot below 1000 feet AGL on takeoff.
For single channel operation during approach, the autopilot shall not remain engaged below 50 feet AGL.
For manually flown HGS AIII Approach, the autopilot shall not remain engaged below 500 feet AGL.
Use of aileron trim with auto pilot engaged is prohibited.
Engine warm up
Engines must be operated for a minimum of 3 minutes prior to takeoff.
Engine cool down
Engines must be operated at or near idle (taxi thrust acceptable) for a minimum of 3 minutes prior to shut down.
Maximum time limit for take of thrust
5 minutes
Maximum start EGT
725°
ENGINE IGNITION
Engine start switches must be in the CONT position for:
- Takeoff
- Landing
- Anti ice operation
- Operation in hail, sleet or moderate to heavy rain
Engine start switches must be in the FLT position for:
• Operation in severe turbulence
Starter duty cycle
• First attempt: 2 minutes on
MAX: 3 minutes on
• Second and subsequent attempts:
10 seconds off , 2 minutes (NG) 3 minutes (MAX) on
REVERSE THRUST
Intentional selection of reverse thrust in flight is prohibited.
APU LOAD
Bleed and electric load….10,000 ft
Bleed Only……..17,000 ft
Electric Only……41,000 ft
Maximum Operating Altitude….41,000 ft
APU GENERAL
Ensure APU BLEED air switch is closed for 2 minutes after start and for 1 minute prior to shut down.
Note: when the APU switch is moved to off, this time delay is met automatically.
APU bleed valve may be open during engine start, but avoid engine power above idle.
Except for engine start, the APU bleed valve must be closed when another source is pressurizing the left bleed air duct.
FLAPS
Maximum flap extension altitude is 20,000 feet.
Holding in icing conditions with flaps extended is prohibited.
SPEED BRAKES
Do not deploy speed brakes with more than Flaps 10 extended.
Do not deploy speed brakes in flight below 1000 feet AGL.
In-flight, do not extend the speed brake lever beyond the flight detent.
Load alleviation system (700W/900ER)
Manually overriding the load alleviation system is not authorized.
FUEL
Minimum fuel temperature is -37°C unless actual fuel freeze point is known.
Allowable lateral imbalance between main tanks 1 and 2 must be scheduled to be zero.
Transient fuel in balance must not exceed 1000 lbs for taxi, take off, flight or landing.
Main wing tanks must be scheduled to be full if the center tank contains more than 1000 lbs.
CENTER TANK FUEL PUMPS
For ground operation, center tank FUEL PUMP switches must not be positioned to ON unless the center tank fuel quantity exceeds 1000 pounds, except when defueling or transferring fuel.
Center tank fuel pumps must not be ON unless personnel are available in the flight deck to monitor LOW PRESSURE lights.
For ground and flight operations, the corresponding center tank fuel pump switch must be positioned OFF when the LOW PRESSURE light illuminates. If the center tank is empty, position both center tank FUEL PUMP switches OFF.
HYDRAULICS
Ground operation of electric hydraulic pump requires a minimum of 1675 lbs in the
respective fuel tank.
Minimum engine oil temperature before setting take off trust (MAX)
31° C
