31

Airport taxiways are identified at night by omni directional edge lights in what color

Blue

32

If the aircraft ammeter is indicating a minus value, this means the

Generator or alternator output is inadequate

33

The angle formed by the chord of an airfoil and the direction of the relative wind is called the

Angle of attack

34

Aircraft Structure

Fuselage Wings (w/ ailerons and flaps) Empennage (tail) Landing Gear Power Plant

35

Empannage Parts

Fixed: Vertical stabilizer and horizontal stabilizer
Moveable: Rudder, elevator, trim tabs

36

Power Plant Parts

Engine Propeller

37

What does the cowling do

Helps cool the engine

38

Propeller creates

Thrust

39

What does the rudder do

Moves the airplane nose left and right

40

What does the elevator do

Moves airplane nose up and down

41

Atmospheric pressure

Weather changes help lift airplane, actuates some flight instruments

42

Air Density

Effects airplanes capability

43

Less dense air

reduces power, thrust and lift

44

Density

Increases with altitude

45

Increase temps

Decreases density

46

Newtons Laws of Motion 1

Body at rest remains at rest

47

Newtons Laws of Motion 2

Constant force creates acceleration proportional to mass

48

Newtons Laws of Motion 3

One body exerts force on another, 2nd exerts force equal to 1st but in opposite direction

49

Magnus Effect

Low pressure upward force

50

Axes of Flight

Pitch Roll Yaw

51

Pitch

Lateral Axis (thru wings) Nose and Tail up and down Elevators

52

Roll

Longitudinal Axis (thru body) Wings up and down Ailerons

53

Yaw

Vertical Axis (up and down) Wings side to side Rudder

54

Rudder

Push left pedal, rudder moves left, moves tail to right and nose to the left.

55

Secondary Flight Controls

Flaps, leading edge devices, spoilers and trim devices

56

Trim Systems

Relieve pilot of the need to maintain constant pressure on flight controls

57

Altimeter Purpose

One of most vital instruments in aircraft. Measures where aircraft is at in atmosphere presents as altitude.

58

Altimeter Hands

Short: 10,000's feet
Middle: 1,000's feet
Long: 100's feet

59

Vertical Speed Indicator VSI or VVI

Indicates whether plane is climbing, descending or in level flight

Ex: rate of climb 500fpm

60

Airspeed Indicator

Pressure measured, different colored arcs.
White-Flap operating range
Yellow-Caution range
Red-Never exceed speed
