Q

What is the ‘gross climb gradient?

A

This is the percentage of change in height divided by horizontal distance travelled in a given time. (this uses geometric rate of climb, not pressure rate of climb).

Q

Weight/Altitude/Temperature (WAT) limit?

A

This is the minimum climb gradient required in each takeoff and climb segment.
Considerations: Aircraft weight, pressure altitude, and ambient air temperature.
This is provided by AeroData on dispatch release.

17
Q

What is the ‘Approach climb requirement’?

A

Missed approach
engine out
speed at V2
Minimum of 2.1% climb gradient to acceleration height

18
Q

What is the ‘landing climb requirement’?

A

Missed approach
all engines operating
gear extended
landing flaps

19
Q

What is the ‘acceleration height’?

A

Minimum altitude after takeoff for: retraction of flaps, climb speed acceleration (Vfto).
This must be done within 5 minute takeoff thrust limit.
Must be at a minimum of 400’ as absolute lowest acceleration height.

20
Q

What is V1?

A

Minimum speed following critical engine failure that a pilot can continue the takeoff and clear any obstacles. This is also the max speed a pilot must take action to stop the aircraft within the accelerate-stop distance (this will use brakes, spoilers, and reversers).

21
Q

What is Vr?

A

Rotation speed
Pilot begins to pull the aircraft off the ground.
Completed when the aircraft is airborne.

22
Q

What is V2?

A

Takeoff safety speed.

23
Q

What is Vfto?

A

Final takeoff speed

24
Q

What is Vef?

A

This is the speed at which the critical engine is presumed to have failed.

25
Q

What is Vyse?

A

This provides a single-engine best rate of climb.

26
Q

What is Va?

A

This is design maneuvering speed. Should be used at or below this to avoid structural damage during an encounter with turbulence.

27
Q

What is Vref?

A

Threshold crossing speed.

Aircraft should be at Vref at 50’ above the runway.

28
Q

What is Vapp?

A

Full configuration approach speed (includes gear and flaps).

29
Q

What is ‘FRA’?

A

Flaps retraction altitude

30
Q

What are some performance factor considerations regarding weather?
Think runway conditions…

A

Dry - a dry runway (no issues)
Wet - < 1/8” water or slush covering intended takeoff surface
Contaminated - > 1/8” water, slush, compact snow, ice covering intended takeoff surface
Damp - not perfectly dry but considered dry for performance purposes

31
Q

What is the wet runway correction factor?

A

115% added to the normal landing distance (dry).

32
Q

First officer with less than 100 hrs - What are his limitations?

A

Captain must make all TO&Ls when: 1. at all special use airports

  1. visibility at or less than 3/4 SM or RVR at or less than 4,000’
  2. Runway is contaminated
  3. Braking action less than good
  4. crosswind component grater than 15 kts
  5. windshear reported in vincinity
33
Q

What is the policy regarding captains fuel? United policy?

A

Up to 1,000# authorized without dispatcher notification - cannot bump pax off. Requests above 1,000# must be discussed with dispatcher and require a new release.

34
Q

What is the policy regarding captains fuel? Delta policy?

A

No captains fuel - all requests must go through dispatch and obtain a new release if fuel is granted.

35
Q

What are the differences between method #1 and #2?

A

Method #1 (uses no alternate) - 1,000’ terrain and obstruction clearance, and must be able to climb to 1,500’ above airport elevation. Must maintain vertical clearance with horizontal clearance of 5 SM on either side of route.
Method #2 (uses enroute alternate) - 2,000’ terrain and obstruction clearance, and must be able to climb to 1,5000’ above airport elevation. Must maintain vertical clearance with horizontal clearance of 5 SM on either side of route.

36
Q

What is the limitation on flight with the landing gear down?

A

Flaps and slats must be fully operational.
Flight in known or anticipated icing is prohibited.
Max airspeed - 220 knots Vle.
Cat II ops prohibited.

37
Q

What is the notice regarding manual deployment of the landing gear?

A

The mains will fall down by gravity pull, but the nose gear will not fall by any means (will remain locked in the up position).

38
Q

How much does each start attempt of the APU reduce the life of the battery?

A

6 minutes

39
Q

What is this code - CRJ7/M-DGE3LORVWZ/S

A

CRJ7 - CRJ 700 /M - turbulence class medium
D - DME G - GPS E3 - ACARS L - ILS
O - VOR R - RNAV enabled V - VHF radio
W - RVSM Z - Other equipment /S -
