Flight Performance and Planning Quiz 1

Question 1) What does the green arc on the airspeed indicator show?

VNE range

Caution range

Flap operating range

Normal operating range

Correct! Wrong!

The green arc indicates the normal operating range of the aircraft from Vs1 to Vno.

Question 2) What will ground effect result in?

An increase in both lift and drag

An increase in lift and a reduction in drag

A reduction in lift and an increase in drag

A reduction in both lift and drag

Correct! Wrong!

Ground effect will increase lift and reduce drag and cause the aircraft to float near to the ground. Ground effect is said to take effect when the aircraft is ‘half a wingspan’ or less with relation to the ground.

Question 3) How much would you expect the landing distance to increase when landing on short, wet grass?

60%

50%

40%

30%

Correct! Wrong!

The safety factor for short, wet grass on the landing distance is 1.3

Question 4) When using runway 27, the surface wind is 300/28. What is the approximate crosswind component?

20 knots

14 knots

7 knots

10 knots

Correct! Wrong!

To work out the crosswind component that calculation is. Wind speed x Sine (Angle between the wind direction and runway). 28 x sin(30) = 14kts.
