Q

De rated thrust take off

A

Carried out on both dry and wet runways
Full or TOGA thrust cannot be selected
Lower values of Vmcg and Vmca

22
Q

TODN-1

A

Loss of one engine at V1

23
Q

VEF

A

Engine failure speed
Directional control from VEF - 1 sec before V1
Faster than VMCG

24
Q

VMU

A

Minimum unstick speed
Lowest CAS ac can safely lift off ground and takeoff without hazard
Reduces as air density increases

25
Q

Vr/VLOF speeds on Class A

A

1.10VMU all engine/1.05VMU one engine (aerodynamically limited)
1.08VMU all engine/1.04VMU one engine (geometry limited)

26
Q

V2 speeds

A

1.1 VMC
1.13 VSR1

4 engine turbo prop 1.08 VSR1

27
Q

Calculating TOD on dry runway - Field Length Requirements specified in CS25

A

TODN x 1.15
TODN -1 (no safety factor applied to one engine)
Brakes release to midway between VLOF and screen height

28
Q

Calculating V1 wet

A

Find the greatest of
TODN-1 wet - (no safety factor)
TODN DRY - 1.15 safety factor
TODN1 dry (no safety factor)

Greater of the above

29
Q

Landing on a flooded runway in stormy conditions

A

Increase approach speed - prevent stall from increased drag from rain

Land firmly to obtain firm contact of wheel with runway

Use all lift dumper devices

Apply brakes up to anti skid activation

30
Q

De rated vs flex thrust

A

De rated - allows for operation on all runways

Reduced thrust - not allowed on contaminated runways/anti skid inop/Windshear

31
Q

CLTOM is increased when

A

Lower flap setting =higher gives more drag reducing excess thrust therefore lower increases climb limited take off mass

Higher air density = lower altitude more dense therefore more thrust giving a higher CLTOM

Lower outside air temperature = increased density improving gradient

32
Q

Approach Climb OEI - two engine climb gradient

A

Not less than 2.4% climb gradient

33
Q

Approach climb OEI - three engined aeroplane climb gradient

A

2.7%

34
Q

Approach climb OEI - four engined aeroplane - climb gradient

A

3% CLIMB GRADIENT

35
Q

Definition of V1

A

The decision speed or action speed

Maximum speed at which pilot must take action to stop within the remaining ASD

Minimum speed following engine failure pilot is able to continue take off within the remaining take off distance.

36
Q

With an addition of a stopway what happens to the mass and V1 speed

A

Increase TOM
Increase V1 speed

More runways to use in the ground roll and be within the ASD

37
Q

With the addition of a clear way what is the impact on mass and V1

A

Mass can increase
V1 speed decreases

38
Q

Class A landing climb gradient should not be less than

A

3.2% landing config

39
Q

Aqua planning is most likely when

A

On touch down when the tyres are not spinning increasing the risk of hydro planning

40
Q

Reduced thrust (de rated) implications

A

Slower acceleration
Longer take off run
Slower climb and increased fuel burn

Not used on:
Contaminated runways
Anti ski inop
Increased V2 procedure
Windshear expected

41
Q

Final take off speed VFTO must not be less than

A

1.18VSR and provide minimum climb gradient
(Segment 3)

42
Q

Quick turn around limit is related to

A

The absorption of heat by the brakes on landing that must be planned for when taking off on a short turn around

43
Q

What can you do to increase your field length limited take off mass

A

Selecting the highest take off flaps within limits
Performing a packs off takeoff

44
Q

Tyre speed limit

A

Rotation rate of the tyre and temperature

45
Q

What speeds are used to determine V2MIN
Class A
Class B

A

Class A:
1.13VSR for 2 engine/3 engine
1.08SR for turboprops with more than 3
1.1VMC

Class B:
VMC for single engine
1.1VMC for twin
VS1

46
Q

V1 reduced - obstacle clearance and climb performance for OEI will

A

Obstacle clearance will decrease - more distance required to accelerate to VLOF

Climb performance will be constant - factored into the climb performance

47
Q

If you rotate too quickly

A

Lift off may be too slow and insufficient above VMCA and VMU for safe flight

Aeroplane climb shallower than planned angle

Risk of tail strike

Reduce margin above VMCA and VSR

Aircraft may not lift off

48
Q

VR has a safety margin of

A

At least 5% above VMC
Almost 10% above the stall

49
Q

What assumptions are made to calculate ASD N1

A

Come to a full stop without using reverse thrust on a dry runway from the highest speed reached

Add a distance equivalent to 2 seconds at the V1 speed

Accelerate the aircraft from a standing start with all engines operating to VEF for take off from a dry runway

Allow ac to accelerate from VEF to highest speed reached during rejected take off

50
Q

Screen height for take off from a dry runway is verses wet runway

A

Screen height on dry runway is 35ft
Screen height on wet runway is 15ft

51
Q

V1WET vs V1

A

V1WET is lower than V1 due to the reduced ability to de accelerate on runway

52
Q

Purpose of V1 wet is to

A

Prevent an excessively restricted RLTOM

53
Q

Pilot uses flex thrust and then decides to use TOGA what is the effect os using TOGA

A

Increased performance
