Module 2 - You Airplane & Aerodynamics

Question 1

What are the primary flight controls

Answer 1

Ailerons
Elevator
Rudder

Question 2

What are the secondary flight controls?

Answer 2

Flaps
leading edge devices
spoilers
trim

Question 3

What is the purpose of the flaps?

Answer 3

To enable the pilot to make steeper approaches to landing without increasing airspeed.

Question 4

What is the purpose of the rudder?

Answer 4

To control yaw.

Question 5

Which of the following is true concerning primary flight controls?

Answer 5

The effectiveness of each control surface increases with speed because there is more air flowing over them.

Question 6

What are the four forces acting on our aircraft in flight at all times?

Answer 6

Life, Weight, Thrust, Drag

Question 7

What is accelerated flight?

Answer 7

When all four forces are equal we are in accelerated flight.

Question 8

Air traveling over the curved upper surface of an airfoil causes low pressure on the upper surface.

Answer 8

Bernoulli’s Principle

Question 9

Air traveling over the curved upper surface of an airfoil cuases low pressure on the upper surface.

Answer 9

Bernoulli’s Principle

Question 10

The difference between the chord line and the relative win.

Answer 10

Angle of attack

Question 11

Where all of the lift is concentrated on the wing.

Answer 11

Center of pressure

Question 12

Where the aircraft will balance and relates to our stability.

Answer 12

Center of gravity. (CG)

Question 13

What is a forward center of gravity great for?

Answer 13

Stability

Question 14

Is a AFT CG more or less table?

Answer 14

Less

Question 15

What force helps a aircraft through a turn?

Answer 15

Horizontal component of lift.

Question 16

As altitude increases, the indicated airspeed at which a given airplane stalls in a particular configuration will?

Answer 16

A A/C can stall at any airspeed, but it will always stall at the same critical area of attack.

Question 17

What flight condition must an aircraft be placed to spin?

Answer 17

Stalled

Question 18

What is ground effect?

Answer 18

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

Question 19

An aircraft said to be inherently stable will?

Answer 19

Require less effort to control.

Question 20

P Factor is how many types of left turning tendencies?

Answer 20

P Factor is one of four left turning tendencies.

Question 21

What does p-factor cause the airplane to the left?

Answer 21

When at high angles of attack. The descending propeller has a greater angle of attack.

Question 22

Torque

Answer 22

for every action there is an opposite reaction.

Question 23

Descending blade creates a larger angle of attack

Answer 23

P-Factor

Question 24

A spinning disc has rigidity in space.

Answer 24

Gyroscopic preciession

Question 25

Corkscrew airflow impacts the tail section.

Answer 25

Spiraling Slip Stream

Question 26

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

Answer 26

speed of the airplane

Question 27

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

Answer 27

Turns

Question 28

What changes the basic aerodynamic shape of the wing, but the roughness of its surface spoils the smooth flow of air, thus causing an increase in drag and an early airflow separation over the wing, resulting in a loss of lift.

Answer 28

Frost

Question 29

The greater the load (whether from gross weight or from centrifugal force), the more life is required. Therefore, and aircraft will _____ at higher airspeeds when the load and/or load factor is increased.

Answer 29

stall

Question 30

Which V-speed represents maneuvering speed?

Answer 30

Va

Question 31

Which V-speed represents maximum landing gear extended speed?

Answer 31
