Q

In headwing, takeoff distance is ____

A

reduced

17
Q

To estimate strength of crosswind component at a runway, these mental calculations:

A

If the wind is 30° off the runway heading, crosswind component is 1/2 of the wind strength
if 45°, 2/3
if 60°, 9/10
if 90°, full crosswind speed

18
Q

Calculate crosswinds and tailwinds revision1!!!

A
19
Q

Poor runway surface _____ the take-off ground run

A

increases

20
Q

Grass runway increases the length of the take-off distance by

A

20-30%

21
Q

A downslope will ______ the ground run

A

Decrease

22
Q

A 2% upslope will increase the takeoff distance by

A

10%

23
Q

Crosswind component calculation

A

Wind speed * sin (wind direction - runway direction)

24
Q

Headwind/ tailwind component calcualation

A

Wind speed * cos (wind direction-runway direction)

25
Q

ED

A

Emergency distance

26
Q

LDA

A

Landing distance available

27
Q

Same as takeoff distance, landing distance is considered to be

A

When 50ft above the runway until a full stop

28
Q

A landing speed will usually be

A

1.3Vstall

29
Q

Forces affecting landing performance

A

Weight (because of increased stall speed + braking has more work)
Density altitude
Wind
Surface
Flaps
Slope

30
Q

In a low density air, the true air speed is ______

A

Higher than IAS

31
Q

If landing in low density, the ground run will

A

Longer, because the true airspeed is bigger

32
Q

The ground speed of landing in low density will be

A

Higher

33
Q

A headwind ______ ground speed

A

Reduces

34
Q

A wet runway will result in

A

Longer landing distance

35
Q

Aquaplaning

A

The wheel skating on a wet surface but no rotating

36
Q

A downslope will require

A

Longer landing distance
