Q

While sitting at the gate with engines shutdown you notice a “Fuel Imbalance” message. Can you transfer fuel at this time?

A

No, fuel transfer requires 115v variable AC which is not available without ground AC or an AC generator on line.

Q

@Can you start engines to depart with less than MT if you have extra CT fuel?

A

No. Fuel on board at time of engine start (for purpose of flight) must be equal to or greater than MT.
In no case will a flight depart with less than “Minimum Total Fuel” on the Dispatch Release.

19
Q

Can the right wing be gravity fueled during the boarding process?

A

Yes.
(Over-wing refueling of the RIGHT wing tank may be accomplished while enplaning or deplaning).

FOM 7.2.4

20
Q

Can the left wing be gravity fueled with passengers onboard?

A

Yes.
(Over-wing refueling of the LEFT wing tank may be accomplished while passengers remain onboard).

FOM 7.2.4

21
Q

Can the APU be operated during gravity refueling?

A

No.

FSM 1.8.3

22
Q

Can the APU be started while pressure refueling?

A

No.

FSM 1.8.3

23
Q

Will the deice boots operate with the BLEED switches in the OFF position?

A

Yes.
A constant supply of de-icing bleed air is provided by the bleed system of each engine, regardless of engine bleed control switch position.
SDM 13-6

24
Q

When must the REF SPEEDS switch be selected to INCR?

A

At initial detection of ice formation anywhere on the aircraft or when the ICE DETECTED advisory appears on the ED. It shall remain selected to INCR until the wings are aerodynamically clean.
FSM 7.2.3

25
Q

Taking off into icing conditions is defined as reaching icing conditions by what altitude?

A

Acceleration height.

FSM 7.2.5

26
Q

When will the Engine Intake HTR light illuminate?

A

The intake heaters automatically activate under the following conditions:
- Engine Intake Bypass Doors are open, AND
- Engine is running (oil pressure sensor), AND
- SAT is below ~15*C (temperature sensor), AND
- 115v variable AC power is available.
SDM 13-14

27
Q

When are the deice boots required to be used?

A

At initial detection of ice formation anywhere on the aircraft or when the ICE DETECTED advisory appears (flashing or steady) on the ED. Once selected, the airframe deicing equipment shall remain operating until clear of icing conditions.
FSM 7.2.2

28
Q

When may the wing and tail deicing boots be turned off?

A

When clear of icing conditions, allow two entire cycles, then AIRFRAME MODE SELECT selector switch to MANUAL. At pilot’s discretion, ice equip may remain selected on if icing conditions are expected to be encountered again, or if significant residual ice is evident. Due to “cold-cracking,” deice boots shall be selected off when SAT is -40*C or less. FSM 7.2.2 & 7.2.11

29
Q

While sitting at the gate with engines shutdown you notice a “Fuel Imbalance” message. Can you transfer fuel at this time?

A

No, fuel transfer requires 115v variable AC which is not available without ground AC or an AC generator on line.

SDM 11-10

30
Q

@Can you start engines to depart with less than MT if you have extra CT fuel?
