Q

Newton’s 1st Law?

A

An object at rest will remain at rest, or an object in motion will continue in motion at the same speed and in the same direction, until acted upon by an outside force.(inertia)

Q

Newton’s Second Law?

A

(Force) if an object moving with uniform speed is acted upon by external forces, the change if motion, or acceleration, will be directly proportional to the amount of force and inversely proportional to the mass of the object being moved.

Q

Bernoulli’s Principle?

A

When a fluid flowing through a tube reaches a construction or narrowing if the tube, the speed of the fluid passing through the constriction is increased and it’s pressure decreased.

Q

Lift?

A

The force that acts, in an upward direction, to support the aircraft in the air. Must be greater than or equal to weight if flight is to be sustained.

Q

Drag?

A

The forces that tends to hold the aircraft back. Caused by disruption of air about the wings, fuselage or body, and all protruding objects on the aircraft.

Q

Lateral axis?

A

An imaginary reference line running parallel to the wings.

17
Q

Vertical axis?

A

An imaginary line running from top to bottom of the aircraft

18
Q

Ailerons?

A

Roll longitudinal

19
Q

Elevators?

A

Pitch lateral

20
Q

Rudder

A

Yaw vertical

21
Q

Cyclic stick?

A

(Roll/pitch) tilts the plane and changes direction of lift

22
Q

Tail rotor?

A

(Yaw) counteracts torque of main rotor by increasing or decreasing the amount of horizontal thrust the tail rotor produces.

23
Q

Creates lift by lengthening the top section of the wing resulting in maximum lift to reduce takeoff runs and landing roll out?

A

Flap (leading/trailing edge)

24
Q

Used to decrease wing lift by destroying the smooth flow of air over the wing surface, creates a more predictable landing glides cope?

A

Spoiler

25
Q

Hinged or movable control surfaces used for reducing the speed if the aircraft. Location varies on models of aircraft?

A

Speed brakes

26
Q

Movable control surfaces attached to the leading edge of the wing?

A

Slats

27
Q

Lift may be changed ________ by increasing the angle of attack or pitch of the rotor blades?

A

Collectively

28
Q

Angle at which the airfield or fuselage meets a flow of air?

A

Angle of attack (AoA)

29
Q

AoA is defined as?

A

The area between the chord line of the wing and the relative wind.

30
Q

What is relative wind?

A

Direction of air stream in relationship to the wing.

31
Q

AoA is measured in?

A

Units

32
Q

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

A

Autorotation

33
Q

Basic aircraft hydraulic system?

A

A reservoir to hold a supply of Hyd fluid
A pump to provide a flow of fluid
Tubing to transmit the fluid
A selector valve to direct the flow if fluid
An actuating unit to convert the pressure into useful work

34
Q

Main landing gear components?

A 
Shock strut assembly
Tires 
Wheel brake assembly
Retracting and extending mechanism
Side strut supports
35
Q

Provides lateral strength/support for the landing gear?

A

Side struts and supports

36
Q

Used to slow and stop the aircraft, and prevent aircraft from rolling while parked?

A

Wheel brake assembly

37
Q

All necessary hardware to electrically or hydraulically extend and retract the landing gear?

A

Retracting and extending mechanism

38
Q

Allows aircraft to roll easily and provides traction during takeoff and landing?

A

Tires

39
Q

Absorbs the shock that otherwise would be sustained by airframe?

A

Shock strut assembly
