8,000 ft

41,000 ft

• Upper ISA + 35 deg C
• Lower -40 deg (C and F)

Flight must be within 60 minutes of a suitable airport if cargo is carried in either compartment

The Taxi lights must be switched OFF whenever the airplane is stationary in excess of 10 minutes

Brake cooling times must be observed between a landing or a low energy RTO and a subsequent takeoff to ensure that sufficient brake energy is available to bring the airplane to a complete stop if the subsequent takeoff is rejected. See ODH. Min time is 15 minutes with BTMS operative.

• 25,000 ft
• 31,000 ft

31,000 ft

...the airplane must be completely depressurized

...use of EMER DEPRESS switch above 15,000 feet is prohibited

Operation with the Autopilot engaged is prohibited at altitudes below: 600 ft AGL

Operations with an ILS glidepath angle that exceeds 3.5 degrees are prohibited.

Minimum use height for ILS (2-engine): 80' AGL

MInimum use height for ILS (1-engine): 110' AGL

MInimum use height for visual or non-precision approach: 400' AGL

...the ADC coupled to the active Autopilot must also be coupled to the ATC transponder

Maximum electrical load limit (kVA) for a main generator or APU: 40 kVA

Maximum continuous permissible load on a TRU in flight: 120 Amps

Maximum time for ground operations on DC ground power: 5 minutes (to protect CRT displays)

A circuit breaker must not be reset or cycled:

• Unless doing so is consistent with explicit procedures specified in the QRH

                 or

• Unless, in the judgement of the PIC, that resetting or cycling the circuit breaker is necessary for the safe completion of the flight

When setting the MDA marker on the baro altimeter using the DH/MDA knob on the Air Data reference panel, the next highest 10 foot increment must be set if the altitude is not a 10 foot increment.

Pilots are authorized to deviate from an ATC clearance to comply with a TCAS RA

• The cowl anti-ice must be ON when the OAT is 10 deg C or below and visible moisture in any form is present (FG with vis 1SM or less, rain, snow, sleet, ice cystals)
• The cowl anti-ice must be ON when the OAT is 10 deg C or below and when operating on ramps, taxiways, and runways where surface snow, ice, standing water, or slush is present

In flight, the cowl anti-ice must be on when:

• In icing conditions
• When ICE is annunciated by the ice detection system

Icing conditions exist in flight:

• at a TAT of 10 deg C or below, and
• Visible moisture in any form is encountered (such as clouds, rain, snow, sleet, or ice crystals), except when the SAT is -40 deg C or below.

• The wing anti-ice system must be ON for takeoff when the OAT is 5 deg C or below and visible moisture in any form is present.
• Also, when the OAT is 5 deg C or below and the runway is contaminated with surface snow, slush, or standing water.
• When Type II, III, or IV anti-icing fluids have been applied, the wing anti-ice must only be selected on, if required, just prior to thrust increase for takeoff.

The Wing Anti-Ice system must be ON when

• ICE is annunciated by the ice detection system
• When in icing conditions and the airspeed is less than 230 KIAS

Do not hold in icing conditions with the slats/flaps extended
