Do not engage autopilot for takeoff below 400 feet.
Single channel operation during approach- not below 50 feet.
OMA:
Manual landing or visual approach not below 500 ft AAL.
instrument approach which is not a precision approach below the
MDA or 50 ft below the DA
Max & min glideslope angles
2.5 - 3.25
Autoland
Only using flaps 30 or 40 and both engines operative.
Engine ignition must be on
Takeoff
Landing
Operation in heavy rain
Anti ice operation
Intentional selection of the revers thrust in flight
Is prohibited
APU in flight
Bleed + electrical max 10,000 ft inflight & 15,000 ft ground only
Bleed only max 17,000 ft
Electrical only max 41,000 ft
APU bleed must be closed when
Ground air connected and isolation valve open
Engine no. 1 bleed valve open
Isolation and engine no. 2 bleed valve open
APU valve maybe open during engine start, but avoid above idle power
APU start
After three consecutive aborted start attempts, a 15 min cooling period is required
Max flap extension altitude
20,000 ft
Holding in icing conditions with flaps extended
Is prohibited
Flight controls operation
Avoid rapid and large alternating control inputs
Do not deploy speedbrakes inflight below radio altitude
Of 1000 ft
Alternate flap duty cycle
After moving the flaps in alternate allow 15 seconds to avoid damage to alternate flap motor clutch
After a complete cycle extend/retract allow 5 min cooling before attempting another try
ADIRU alignment
Should not be attempted at latitudes greater than 78 degrees
Look Ahead Terrain Alerting (GPWS)
Do not use terrain display for navigation
Do not use terrain alerting and terrain display for takeoff, approach and landing within 15 NM of airports not contained in database
Weather radar
Do not operate in a hangar or when personnel are within the
area normally enclosed by the aircraft nose radome or within 50 feet of a fuel spill.
Fuel tank limitations

Max - 950
Between 925-950 max 5 min
The dispatch from/ to runways less than 45-meters wide is not allowed in case of
nose gear steering inoperative or one thrust reverser inoperative.
If an alternate airport is available with a runway at least 45-meters wide, diversion to that alternate shall be performed in case of jammed or restricted flight controls, trailing edge flap asymmetry, leading edge flap/slat asymmetry, or loss of system A or B
