Answer 2

Parasite Drag
Three Types: Skin Friction Drag, Form Drag, Interference Drag

Question 3

Induced Drag

Answer 3

Drag Associated with the production of lift.

Question 4

Interference drag

Answer 4

Result of interaction airflow from joined components of airframe.

Question 5

Bernoulli’s Principle

Answer 5

As the velocity of fluid increases the pressure of that fluid decreases.

Question 6

Newtons 3rd Law of Motion

Answer 6

To every force there is a equal or opposite force.

Question 7

Lift

Answer 7

Upward force which sustains the aircraft in flight

Question 8

What are the Four Left Turning Tendencies?

Answer 8

-Torque
-P-Factor
-Spiraling Slipstream
-Gyroscopic Procession

Question 9

Results in Forward Center Gravity

Answer 9

Nose Heavy
More Tail down force

Question 10

Result in Aft Center Gravity

Answer 10

Tail Heavy
Less tail down force

Question 11

What are the Four Left Turning Tendencies

Answer 11

Torque, P-Factor, Spiraling Slipstream, Gyroscopic Processing

Question 12

What is Torque (LTT) What Axis.

Answer 12

The propellor turning in a clockwise way.
Longitudinal Axis
Prop. Connected to the crankshaft which is connected to the airplane.

Question 13

What is P-Factor?

Answer 13

-As the pitch of the aircraft changes so does the orientation of the prop, pushing the right wing up more and the left side down causing LTT.

Question 14

What is Spiraling Slipstream?

Answer 14

The action of the airflow going around the plane in a clockwise motion striking the left side of the vertical stabilizer, resulting in a yawing motion to the left.

Question 15

What is Gyroscopic Procession? What Axis?

Answer 15

When the Gyro(Prop) is rotated at high speeds which then a force is applied to the gyro 90° in the direction from which the force is applied.

Question 16

What is Dihedral Angle

Answer 16

The upwards angle of wings which affect lateral stability in a bank.

Question 17

Stall

Answer 17

-Where the airflow goes over the wings. Wing is no longer producing lift resulting in a loss of altitude.
-Any airspeed and height.

Question 18

What is a Spin

Answer 18

-Result of aircraft stalling in uncoordinated position.
-Flight path in a spin is nearly vertical.
Wing on outside rotation is producing more lift.

Question 19

Recovery of a spin (RCT)

Answer 19

-Rudder: Opposite rotation
-Control Wheel: Full Forward/ Aileron Nutral
-Throttle: Idle

Question 20

Purpose of Flaps Takeoff and Landing

Answer 20

Takeoff: Allows aircraft to become airborne sooner, minimizes ground roll.
Landing: Allows for increase decent angle, slower airspeed, ground roll reduced.

Question 21

What changes do flaps cause?

Answer 21

-Extension increases chamber of wing
-Changes angle of attack
-Change in lift
-Change in drag.

Question 22

4 Types of Flaps (PSSF)

Answer 22

Plain, Split, Slotted, Fowler

Question 23

Chord Line

Answer 23

Imaginary line that accurately detonates the angle of attack relative to airflow.

Question 24

Angle of Attack

Answer 24

-Angle on which the chord log an aircraft wing meets relative wind.
-Slower speed=higher angle of attack.

Question 25

3 Axis of Airplane and their controls

Answer 25

-Longitudinal: Roll(Ailerons) -Lateral: Pitch(Elevators) -Vertical: Yaw(Rudder)

Question 26

Adverse Yaw

Answer 26

The initial pull in the opposite direction than the desired direction.

Question 27

What is Vx and Vy

Answer 27

-Vx: Best angle of Climb -Vy: Best rate of Climb

Question 28

Indications of Imminent stall (3)

Answer 28

-Loss of control effectiveness -Buffeting of Airframe -Stall warning Horn

Question 29

Slip

Answer 29

-Result of horizontal lift being greater than the centrifugal force. -Excessive Bank angle.

Question 30

Skid

Answer 30

-Result of centrifugal force being great than the horizontal lift. -Insufficient Bank angle.

Question 31

Ground Effect

Answer 31

-Happens when an aircraft is operating within a wingspan of the ground. - ground inhibits the development of wingtip vortices which reduce downwash.(can’t produce lift)

Question 32

Static Stability

Answer 32

-The immediate tendency of an aircraft when displaced.

Question 33

Dynamic Stability

Answer 33

The tendency of an aircraft over time

Question 34

Design Characteristics (DSK)

Answer 34

-Dihedral -Sweepback -Keel Effect

Question 35

What happens to lift as air density decreases

Answer 35

As air density decreases - Lift Decreases

Question 36

Density Altitude

Answer 36

Pressure altitude corrected for non-standard temperature

Question 37

Relation of Humidity to aircraft performance

Answer 37

High Humidity= decrease aircraft performance

Question 38

Thrust opposes _________ as Lift opposes _________

Answer 38

Drag, Weight

Question 39

Does a piper archer have symmetrical or asymmetrical airfoil

Answer 39

Asymmetrical

Question 40

Angle which an aircraft will stall is called

Answer 40

Critical angle of attack

The difference between basic empty weight and the maximum weight allowed is called:

Answer 41

Useful Load

Question 42

The total weight of the passengers and cargo on board the aircraft is called:

Answer 42

Payload
