basic aerodynamics

Question 1

Which basic flight maneuver increases the load factor on an airplane as compared to straight-and-level flight?

Answer 1

Turns.

Question 2

What is ground effect?

Answer 2

The result of the interference of the surface of the Earth with the airflow patterns about an airplane.

Question 3

What force makes an airplane turn?

Answer 3

The horizontal component of lift.

Question 4

What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not adjusted?

Answer 4

The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced.

Question 5

Changes in the center of pressure of a wing affect the aircraft`s

Answer 5

aerodynamic balance and controllability.

Question 6

During an approach to a stall, an increased load factor will cause the airplane to

Answer 6

stall at a higher airspeed.

Question 7

The wind condition that requires maximum caution when avoiding wake turbulence on landing is a

Answer 7

light, quartering tailwind.

Question 8

(Refer to figure 66.) While practicing S-turns, a consistently smaller half-circle is made on one side of the road than on the other, and this turn is not completed before crossing the road or reference line. This would most likely occur in turn

Answer 8

4-5-6 because the bank is increased too rapidly during the early part of the turn.

Question 9

The amount of excess load that can be imposed on the wing of an airplane depends upon the

Answer 9

speed of the airplane.

Question 10

Loading an airplane to the most aft CG will cause the airplane to be

Answer 10

less stable at all speeds.
