Theory of Flight

Question 1

Induced drag increases as:

1. Veloocity Decreases
2. AOA increases
3. Altitude increases
4. All the above

Answer 1

2. AOA increases

Question 2

Considering a flight in turbulent conditions at a given airspeed, the effect that a decrease in aircraft gross weight will have is that:

1.Acceleration forces will be higher
2. Possitive acceleration forces will be higher, while negative acceleration forces will be lower
3. Acceleration forces will be lower
4. Acceleration forces will show no apperciable variation

Answer 2

1. Acceleration forces will be higher

Question 3

For an aircraft to remain in level flight during a turn, total lift must equal:

1. Drag and weight
2. Thrust and centripital force
3. Centifuhal force and weight
4. Gravitational force and the horizontal component of lift

Answer 3

3. Centrifugal Force and weight

Question 4

If an aircraft is at 10 degrees of pitch, will the angle of attack be greater in a climb or a descent?

1. Descent
2. Climb
3. Level flight
4. Same in aclimb or in a descent

Answer 4

1. Descent

Question 5

Wing tip vortices cause a:

1. Decrease in lift
2. Increase in induced drag
3. NEither a change in lift nor drag
4. 1 and 2

Answer 5

4. 1 and 2

Question 6

When does waketurbulace start and end?

Answer 6

Nose wheel off to nose wheel down
