Thrust is a force produced by the aircraft and in straight and level flight is equal to:
Correct
Incorrect
-
Question 7 of 24
7. Question
In straight and level flight, lift is a force produced by the aircraft and is roughly equal to:
Correct
In normal straight and level flight lift equals weight. The reason we say normal is because an aerobatic aircraft that has extremely high power to weight ratio, may have the ability to sustain altitude from thrust alone. If thrust is equal to or greater than weight then this could be possible.
Incorrect

Question 8 of 24
8. Question
Lift force acts through the:
Correct
In reality lift is generated all over the wing. However the centre of pressure is the net result of all that lift pressure. It is generally located around 1/4 the way back from the leading edge along the chord line. You will not need this much detail.

Weight is a force that acts through the:
Correct
To remember the difference between C of G and C of P. Remember it is weight affected by gravity forcing us downwards and lift affected by pressure lifting us up.
Incorrect

Correct
Incorrect
-
Question 17 of 24
17. Question
Which control surface can change the curvature of a wing?
Correct
Again another loaded question as you will get in your exams. All control surfaces technically change the curvature of a wing. However the best answer and the one we deliberately use to change the entire wing curvature is the flaps.

Correct
The flaps job is to both slow the aircraft and create lift.
Incorrect
The flaps job is to both slow the aircraft and create lift.
