Q

This principle states that when a fluid flowing through a tube reaches a constriction or narrowing of the tube, the speed of the fluid passing thru is increased and its pressure decreased.

16
Q

force that tends to hold an aircraft back; caused by the disruption of the air about the wings, fuselage, or body.

A

Drag

17
Q

force developed by the aircraft’s engine, and acts in the forward direction

A

Thrust

18
Q

On longitudinal axis

A

Ailerons (roll)

19
Q

On lateral axis

A

Elevators (pitch)

20
Q

On vertical axis

A

Rudder (yaw)

21
Q

tilts the angle of rotor blades forward, aft, or sideways, giving helicopter its directional motion

A

Cyclic stick (roll/pitch)

22
Q

counteracts torque of the main rotor by increasing or decreasing the amount of horizontal thrust

A

Tail rotor (yaw)

23
Q

creates extra lift by lengthening the top section of the wing resulting in max lift to reduce takeoff runs and landing rollout

A

Flap

24
Q

used to decrease or spoil wing lift by destroying the smooth flow of air over the wing surfaces

A

Spoiler

25
Q

hinged or moveable control surfaces used for reducing the speed of aircraft

A

Speed brakes

26
Q

movable control surfaces attached to the flaps; when open, a slot is created.

A

Slats

27
Q

the angle at which the airfoil or fuselage meets a flow of air.

A

Angle of Attack

28
Q

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

A

Autorotation

34
Q

pilot determines this by referring to the horizon

A

attitude indicator

35
Q

shows the correct execution of a turn and bank

A

turn and bank indicator

36
Q

an electronic system that allows a friendly craft to identify itself automatically before approaching near enough to threaten the security of other naval units

A

Identification Friend or Foe (IFF)

37
Q

used to detect objects at distances much greater than is visually possible

A

Radio Detection and Ranging (RADAR)

38
Q

One radar range mile is how many microseconds?

A

12.36 microseconds
