Question 1

1If an aircraft's airspeed doubles while everything else stays the same, its lift becomes

Medium

A. unchanged B. four times as large C. twice as large D. half as large

Question 2

2A stall occurs when

Easy

A. the critical angle of attack is exceeded B. the engine is started C. speed is too high D. the aircraft is parked

Question 3

3Drag caused by the production of lift is

Medium

A. induced drag B. skin friction only C. parasite drag D. form drag only

Question 4

4Total drag is minimum at the speed where

Hard

A. lift is zero B. thrust is maximum C. parasite drag is zero D. induced drag equals parasite drag

Question 5

5Parasite drag includes form drag and

Medium

A. thrust B. skin friction drag C. induced drag D. lift

Question 6

6Drag caused by the production of lift, linked to wingtip vortices, is

Medium

A. induced drag B. skin friction only C. form drag D. parasite drag

Question 7

7Induced drag is greatest at

Hard

A. low speeds and high angles of attack B. zero lift C. cruise only D. high speeds

Question 8

8Loading an aircraft so that its centre of gravity is too far aft can make it

Medium

A. more fuel efficient and safer B. heavier C. unstable and hard to control in pitch D. unable to taxi

Question 9

9Increasing the speed of airflow over a wing

Easy

A. stops the engine B. increases lift C. has no effect D. decreases lift

Question 10

10Flaps on a wing are used to

Easy

A. cool the engine B. store fuel C. increase lift at low speeds for take-off and landing D. steer the aircraft
