19
Q

How long do you need to run the engine at idle thrust for cooldown?

A

1 Minute at idle thrust

20
Q

What is the minimum dispatch oil quantity?

A

8 Quarts before engine start, or 7 quarts after engine start

21
Q

Engine warm up procedure?

A

4 Minutes at idle/taxi thrust for cold engines (off for longer than 90 minutes)
2 Minutes for warm engines (off for less than 90 minutes)

A

Landing Gear-UP
Flaps———— UP
Min Airspeed
(In icing conditions only)- 200 Knots

26
Q

What is the intended use of the Thrust reversers?

A

Thrust reversers are intended for use to reject a takeoff or landing only

27
Q

Can you attempt a go around after Thrust Reverser deployment?

A

Do not attempt a goal around procedure after deployment of the thrust reversers following a landing

28
Q

When must maximum reverse thrust be used?

A

Whenever stopping distance is deemed to be critical, and its use will prevent a runway excursion, and when landing on runways with runway condition code, that is 5 or less

A

On dry run weighs 7000 feet or shorter (usable length )

30
Q

When is the use of thrust reversers prohibited?

A

The use of thrust reversers is prohibited to:

Power back operations
Taxi Operations
Thrust levers stabilized in any intermediate position between IDLE reverse and MAXIMUM reverse
