Can you have Icing conditions on the ramps, taxiways, runways, where surface snow, ice, or standing water can be ingested by your engines?
Yes
What is the minimum, and maximum temperature for manual anti-ice operation?
MIN -40°C. MAX 10°C
When is a runway considered contaminated?

200’
Can you do a single-engine go around with the autopilot engaged?
No. Prohibited.
When can you press the approach mode button during localizer capture?
Allowed only when inbound
When is the use of a Yaw Dampener (YD) not authorized?
During takeoff up to 500’
And during Landing
Minimim BATTERY temp to start APU(?)
-20°C
How long can the max APU CONTINUOUS EGT of 717° C be exceeded?
5 Minutes, maximum
For Cat II ILS, what may be the coupled go-around height loss?
50’
How long do you need to run the engine at idle thrust for cooldown?
1 Minute at idle thrust
What is the minimum dispatch oil quantity?
8 Quarts before engine start, or 7 quarts after engine start
Engine warm up procedure?
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)
To increase N2 above 83%, the engine oil temp must be at or above 40°C.
OR
It is acceptable to run the engine at idle/ taxi thrust for at least 8 minutes and check that the temperature is at least 21°C
Engine Starter limits for starting or dry motoring (on the ground)
5 Minutes on, 5 Minutes off
OR
4- 1 minute cycles, 1 minute off.
After that, 1 minute on, 5 minutes off
What denotes the minimum and maximum range on your flight instruments?
RED

40 Minutes
What is your holding configuration?
Landing Gear-UP
Flaps———— UP
Min Airspeed
(In icing conditions only)- 200 Knots
What is the intended use of the Thrust reversers?
Thrust reversers are intended for use to reject a takeoff or landing only
Can you attempt a go around after Thrust Reverser deployment?
Do not attempt a goal around procedure after deployment of the thrust reversers following a landing
When must maximum reverse thrust be used?
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
When may idle thrust reversers be used?
On dry run weighs 7000 feet or shorter (usable length )
When is the use of thrust reversers prohibited?
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
