Air Conditioning
Limitation?
With either one or both engine BLEED air switched on, do not operate air conditioning packs in HIGH for Takeoff, approach or landing.
ENGINE ANTI-ICE (AFM)
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 -40C SAT, Engine anti-ice must be ON prior to and during descent in all icing conditions, including temperatures below -40C SAT.
Auto Pilot
Do not engage the autopilot below 1,000ft AGL on Takeoff. (AFM/ASA)
For single channel operation during approach, the autopilot shall not remain engaged below 50ft. (AFM)
For manually flown HGS AIII approach, the autopilot shall not remain engaged below 500 ft AGL.
Use of Aileron trim with autopilot engaged is prohibited. (AFM)
ENGINES, APU
(Warm up/Cool Down)
Warm-up: Engines must be operated for a minimum of 3 minutes prior to takeoff. (ASA)
Cool-down: Engines must be operated at or near Idle (taxi thrust acceptable) for a minimum of 3 minutes prior to shutdown. (ASA)
ENGINE EGT (AFM)
Maximum Time Limit for Takeoff Thrust
5 minutes
Engine Ignition
ENGINE START switches must be in CONT position for:
Takeoff
Landing
Anti-ice operation
Operation in hail, sleet, or moderate to heavy rain
ENGINE START switches must be in FLT position for:
Operation in severe turbulence
ENGINE OIL SYSTEM
Minimum Oil Temperature before setting takeoff thrust
31C - MAX
Reverse Thrust
Intentional selection of reverse thrust in flight is prohibited.
APU LOAD (AFM)
Bleed and electrical load —— 10,000ft
Bleed Only. —— 17,000ft
Electric Only —— 41,000ft
Maximum Operating Altitude —— 41,000ft
APU General
Ensure APU Bleed air switch is closed for 2 minutes after start and for 1 minute prior to shutdown.
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
20,000ft (AFM)
FLAPS
Holding
Holding in icing conditions with flaps extended is prohibited. (AFM)
SPEED BRAKES
Do not deploy speed brakes in flight below 1000ft
In flight, do not extend the speed brake lever beyond the FLIGHT DETENT. (AFM)
Do not deploy the speed brakes with more than Flaps 10 extended.*
- Although not prohibited, the use of speed brakes with Flaps 1-10 extended should be avoided as much as possible. The use of speed brakes with flaps extended increases loads on the trailing edge flaps, resulting in increase wear and tear.
Load Alleviation (700/900ER)
Manually overriding the load alleviation system is not authorized.
FUEL
Minimum fuel temp
Minimum fuel temperature -37C unless actual freeze point is known.
FUEL
Imbalance
Allowable lateral fuel imbalance between main tanks 1 and 2 must be scheduled to be zero.
Transient fuel imbalance must not exceed 1000lbs for taxi, takeoff, flight or landing.
Main wing tanks must be scheduled to be full if the center tank contains more than 1000lbs.
Center Tank Fuel Pumps
For ground operations, Center Tank FUEL PUMP switches must not be positioned to ON unless the center tank fuel capacity exceeds 1000lbs, except when refueling 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 position OFF when the LOW PRESSURE light illuminates. If the Center Tank is empty, position both Center Tank FUEL PUMP switches to OFF.
Hydraulics
Ground Operation of electric hydraulic pump requires minimum of 1675lbs respective fuel tank.
