In unaccelerated flight

Question 4

Narrow point in a tube is called a _______

Answer 4

Question 5

Bernoulli’s principle

Answer 5

Air traveling faster over a curved upper surface of a wing causes lower pressure on the top surface and higher pressure on the below surface.

Question 6

Laminar flow

Answer 6

Air flows smoothly over the wings surface

Question 7

As angle of attack increases

Answer 7

You increase lift, due to the disruption of air flow over the wings surfaces

Stall (both wings are considered stalled)

Answer 17

Yaw, rudder

Landing an aircraft with the COG most aft will result in instability

Answer 20

At all speeds

Question 21

A severe unrecoverable stall that will inhibit your ability to land the aircraft is

Answer 21

CG AFT LIMITS

Question 22

4 fundamental maneuvers

Answer 22

Straight and level flight, turns, climbs and descents

Question 23

Fact: if you reduce power and don’t adjust contols the plane can tend to pitch down on its own due to less air from the prop slipstream flowing over the wings. (Less down force)

Answer 23

Under the conditions there is a reduced elevator effectiveness and the nose will pitch down (except for T-Tail) when you change the AOA the pressure on the aircraft moves around

Question 24

The horizontal component of lift will make the airplane ______________

Answer 24

Turn

Question 25

True or False changing the AOA will change the center of pressure which will affect aerodynamics balance and controllability?

Answer 25

True

Question 26

Adverse Yaw means

Answer 26

Yawing in the wrong direction during a turn

Question 27

G is defined as

Answer 27

The measurement of load factor on an airplane

Question 28

What will increased load factor do to an airplane at higher speeds?

Answer 28

Cause an airplane to stall

Question 29

What determines the excess load put on a wing?

Answer 29

Speed of the airplane

Question 30

Two left turning tendencies

Answer 30

P-factor and Torque Affect

Question 31

P-factor is

Answer 31

Left turning tendency due to high AOA on take off.

Question 32

Torque affect

Answer 32

Is the tendency of the aircraft to want to operate in a different direction than the prop is turning.

Question 33
