Q

caused by any aircraft surface which deflects or interferes with the smooth airflow around the airplane.

A

PARASITE DRAG

19
Q

results from turbulent wake caused by separation of airflow from the surface of a structure.

A

Form drag

20
Q

occurs when varied currents of air over an airplane meet and interact.

A

Interference drag

21
Q

caused by roughness of airplane’s surfaces. Rough surfaces create small eddies which contributes to drag

A

Skin friction drag

22
Q

Is generated by the airflow circulation around the wing as it creates lift.

A

INDUCED DRAG

23
Q

Lift works opposite of ________.

A

Weight

24
Q

Thrust works opposite of _______.

A

Drag

25
Q

When the forces are balanced, a plane flies in a ______ direction.

A

Level

26
Q

The plane goes____ if the forces of lift and thrust are more than gravity and drag.

A

up

27
Q

If gravity and drag are bigger than lift and thrust, the plane goes

A

down

28
Q

prop spin causes longitudinal axis of a/c to spin in other direction

A

Torque effect

29
Q

resultant reaction when a force is applied to the rim of a rotating disc, the reaction to a force applied to a gyro acts in the direction of rotation and approx 90 degrees ahead where the force is applied.

A

Gyroscopic precession

30
Q
  • during high angle of attack, descending blade takes a
    greater bite than ascending blade due to higher angle of attack.
A

P-factor or asymmetrical thrus

31
Q

as the propeller rotates, it produces a backward flow of air that strikes the left side of the vertical fin.

A

Spiraling slipstream

32
Q

the characteristic of an aircraft in flight that causes it to return to
a condition of equilibrium.

A

Stability

33
Q

Initial tendency to return to original attitude when disturbed.

A

Static stability

34
Q

tends to return to its original
attitude when it’s disturbed.

A

Positive Static Stability

35
Q

tends to stay in its new
attitude when it’s disturbed.

A

Neutral Static Stability

36
Q

tends to continue moving away
from its original attitude when it’s disturbed.

A

Negative Static Stability

37
Q

is how an airplane responds over time to a disturbance

A

Dynamic stability

38
Q

oscillations that dampen
out over time.

A

Positive Dynamic Stability

39
Q

oscillations that never
dampen out.

A

Neutral Dynamic Stability

40
Q

oscillations that get worse
over time.

A

Negative Dynamic Stability

41
Q

is a stress which is a physical quantity that internal
forces exert on each other

A

LOAD

42
Q

is the ratio of the load supported by the
airplane’s wings to the actual weight of the aircraft and its
contents.

A

LOAD FACTOR

43
Q

HOW TO COMPUTE FOR LOAD
FACTOR?

A

LF = 1/cos (angle of bank)
