Q

What is Newton’s First Law of Motion?

A

(Inertia)

  • An object at rest will remain at rest
  • An object in motion will continue in motion at same speed and same direction, until acted upon by outside force

Q

What is Newton’s Second Law of Motion?

A

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

Q

What is Bernoulli’s Principle?

A

When fluid flowing through tube reaches constriction or narrowing of tube, the speed of fluid passing through is increased and pressure is decreased.

Q

In regards to physics of flight and aeronautic terms, what is Lift?

A
  • Force that acts, in upward direction, to support aircraft in air.
  • Lift must be greater than or equal to weight for sustained flight.

Q

In regards to physics of flight and aeronautic terms, what is Thrust?

A
  • Force developed by aircraft’s engine, acts in forward direction.
  • Thrust must be greater than or equal to effects of drag for flight to begin or be sustained.

Q

In regards to physics of flight and aeronautic terms, what is Vertical Axis?

A

Imaginary reference line running from top to bottom of aircraft.

17
Q

(Fixed wing aircraft) In regards to basic aircraft components and equipment, what are ailerons?

A

(Roll) Longitudinal axis

18
Q

(Fixed wing aircraft) In regards to basic aircraft components and equipment, what are elevators?

A

(Pitch) Lateral axis

19
Q

(Fixed wing aircraft) In regards to basic aircraft components and equipment, what is rudder?

A

(Yaw) Vertical axis

20
Q

(Rotary wing aircraft) In regards to basic aircraft components and equipment, what is the cyclic stick?

A
  • (Roll/pitch) Tilts plane of rotor blades forward, aft, or sideways giving helicopter its directional motion by changing lift direction.
  • Vertical to varying degree based on 0 degree centerline.
21
Q

(Rotary wing aircraft) In regards to basic aircraft components and equipment, what is a tail rotor?

A
  • (Yaw) Counteracts torque of main rotor by increasing/decreasing amount of horizontal thrust produced by tail rotor.
  • Movement around vertical axis.
22
Q

In regards to basic aircraft components and equipment, what is the function of a Flap?

A

Creates extra lift by lengthening top section of wing resulting in maximum lift to reduce takeoff runs and landing rollout.

23
Q

In regards to basic aircraft components and equipment, what is the function of a Spoiler?

A

Decrease or spoil wing lift by destroying smooth flow of air over wing surfaces, creating more predictable landing glideslope.

24
Q

In regards to basic aircraft components and equipment, what is the function of Speed Brakes?

A

Hinged or moveable control surfaces used for reducing speed of aircraft.

25
Q

In regards to basic aircraft components and equipment, what is the function of Slats?

A
  • Movable control surfaces attached to leading edge of wing.

- Allows aircraft to be controlled at airspeeds below normal landing speed.

26
Q

In regards to flight terms and conditions, what is a Collective?

A

Changes the pitch angle of all the main rotor blades collectively and independent of their position causing increase/decrease in helicopters total lift.

27
Q

In regards to flight terms and conditions, what is Angle of Attack (AoA)?

A
  • Angle airfoil or fuselage meets flow of air.

- Measured in units instead of degrees.

28
Q

In regards to flight terms and conditions, what is Autorotation?

A

Method of allowing helicopter to land safely from altitude without using engine power.

29
Q

In regards to basic aircraft hydraulic system, what is a Reservoir?

A

Holds hydraulic fluid.

30
Q

In regards to basic aircraft hydraulic system, what is a Pump?

A

Provides flow of fluid.

31
Q

In regards to basic aircraft hydraulic system, what is a Tubing?

A

Transmits fluid.

32
Q

In regards to basic aircraft hydraulic system, what is a Selector Valve?

A

Directs flow of fluid.

33
Q

In regards to basic aircraft hydraulic system, what is an Actuating Unit?

A

Converts fluid pressure into useful work.

34
Q

In regards to landing gear main components, what is the purpose of the Shock Strut Assembly?

A

Absorbs shock that would otherwise be sustained by airframe.

35
Q

In regards to landing gear main components, what is the purpose of the Tires?

A

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

36
Q

In regards to landing gear main components, what is the purpose of the Wheel Brake Assembly?

A

Used to slow and stop aircraft, and also prevent aircraft from rolling while parked.

37
Q

In regards to landing gear main components, what is the purpose of the Retracting and Extending Mechanism?

A

All hardware used to electrically or hydraulically extend/retract landing gear.

38
Q

In regards to landing gear main components, what is the purpose of the Side Struts and Support?

A

Provides lateral strength/support for landing gear.
