Take off

Question 1

Screen height for a class A aircraft?

Answer 1

35ft

Question 2

Screen height for a class B aircraft?

Answer 2

50ft

Question 3

What is the screen height?

Answer 3

It is an imaginary curtain which needs to be cleared by the lowest part of the aircraft

Question 4

What is the take-off distance?

Answer 4

It is the distance from brake release until reaching screen height

Question 5

What is the take-off run?

Answer 5

It is the distance from brake release until lift off

Question 6

In the absence of a headwind, what happens to Vr?

Answer 6

It increases

Question 7

What happens to TOD & TOR with an increase Vr?

Answer 7

Causes both distances to increase

Question 8

What happens to V1 with a heavy aircraft?

Answer 8

It increases

Question 9

An up-sloping runway results in…?

Answer 9

Longer take off distance and a slower acceleration

Question 10

What happens to take off distance with a down sloping runway?

Answer 10

It decreases

Question 11

What does wet and contaminated runways do to take off distance?

Answer 11

Increases it

Question 12

What happens to an acceleration with an increase in flap setting?

Answer 12

As the drag increases it causes the acceleration to decrease so a longer take off distance is needed as it takes longer to reach the needed speed.

Question 13

What happens to the landing distance required with a tailwind?

Answer 13

Increases

Question 14

What happens to the landing distance with a headwind?

Answer 14

It reduces it due to the lower ground speed

Question 15

What is the factor for headwind?

Answer 15

50%

Question 16

What is the factor for tailwind?

Answer 16

150%

Question 17

With an aerodrome at a high pressure altitude, what happens to the take off distance?

Answer 17

It increases as the air is less dense causing a slower acceleration

Question 18

If the air conditioning packs are on during the take-off run, what happens to the thrust and take off run?

Answer 18

Thrust is reduced and take off run is increased

Question 19

What is displacement drag?

Answer 19

The drag from the extra effort of pushing the tyres through a contaminant

Question 20

What is impingement drag?

Answer 20

The drag caused when the contaminant is thrown up onto the undercarriage and aircraft surfaces

Question 21

What happens to the accelerate-stop distance with a downslope?

Answer 21

It reduces
