1

What is acceleration

The rate of change of the speed and or velocity of matter with time

2

What is speed

The rate of movement in terms of distance measures in an allotted amount of time

3

What is velocity

The quickness of speed of an object in a given time and direction

4

What is Newton's first law

(Inertia) an object at rest will stay at rest or an object in motion will stay in motion at the same speed.

5

What's Newton's second law

(Force) the change of motion is directly proportional to the amount of force and inversely proportional to the mass of the object being moved

6

What is Newton's third law

(Action and reaction) every action there is an equal and opposite reaction

7

What is Bernoulli's principle

When fluid flowing through a tube reaches a constriction the speed of the fluid passing through is increased as pressure is decreased.

8

How is lift accomplished

By the difference in the airflow across the air foil

9

What is lift

The upwards force that supports the aircraft in the air. Counteracts weight

10

What is weight

Force of gravity acting downward on the aircraft

11

What is drag

The force that hold the aircraft back. Drag resists motion

12

What is thrust

The force developed by the engine acts in the forward direction

13

What is the imaginary reference line running down the center of the aircraft between the nose and tail

Longitudinal axis

14

What is the lateral axis

And imaginary reference line running parallel to the wings

15

What is the imaginary reference line that runs from the top to the bottom of the aircraft

Vertical axis

16

What flight control controls roll on fixed wing and rotary wing aircraft

Ailerons (fixed wing)
Cyclic stick (rotary wing)

17

What flight control controls pitch on fixed wing and rotary wing aircraft

Elevators (fixed wing)
Cyclic stick (rotary wing)

18

What flight control controls yaw on fixed wing and rotary wing aircraft

Rudder (fixed wing)
Tail rotor (rotary wing)

19

What does a flap do

Creates extra lift

20

What does a spoiler do

Decreases or spoils wing lift by destroying smooth flow of air over the wing

21

What do speed brakes do

Movable control surfaces that reduce the speed of the aircraft

22

What does the tail rotor do

Counteracts the torque of the main rotor with horizontal thrust

23

What do slats do

Allows the aircraft to be controlled at airspeed below normal landing speed

24

What does AOA stand for

Angle of attack

25

What is the angle of attack

The angle of the airfoil or fuselage meets a flow of air. Aids with landing

26

What is auto rotation

A method of allowing a helicopter to land safely from altitude without using engine power

27

What are the five basic parts of the hydraulic system

Remember PARTS
Pump
Actuator
Reservoir
Tubing
Selector valve

28

5 Main components of the landing gear

Shock strut
Tired
Wheel brake assembly
Retracting and extending mechanism
Side struts and supports

29

What does a shock strut assembly do

Absorb the shock when landing

30

What is motion

The act or process of changing place or position Motion is movement
