Q

What will happen to an aircraft if the center of gravity is beyond it’s limit?

A

Aircraft may rotate prematurely on take-off and pitch up during the climb. Longitudinal stability will also be reduced and this can lead to inadvertant stalls and spins. Recoveries from this may be prolonged or impossible.

If the center of gravity is too far forward, the aircraft’s stall speed will be increased

38
Q

What causes wheelbarrowing? What is the result?

A

Occurs when pilot uses excess speed while making an approach in a full flap configration, or during takeoff when the pilot puts too much forward pressure on the control column as the aircraft accelerates.

Result is the main gear lifting off the ground and the nose gear staying on the runway

39
Q

How do you recover from wheelbarrowing?

A

Reduce power, release forward pressure, nose up and full power

40
Q

Describe the three types of hydroplaning

A

Dynamic Hydroplaning: occurs at high speeds with standing water on the runway reducing the aircraft’s cross wind capabilities

Viscous Hydroplaning: occurs at slower speed with only a thin film of water on a smooth runway

Reverted Rubber Hydroplaning: caused when the tires are locked up.

41
Q

What is the formula used to determine dynamic hydroplaning minimum speeds?

A
42
Q

What is the lift drag ratio?

A

The relationship between lift and drag. Obtained by diving the lift coefficient by the drag coefficient

43
Q

What is flight for maximum range? How can it be achieved?

A

The furthest an aircraft can fly per unit of fuel consumed. Can only be achieved by flying at an angle of attack that gives the best lift/drag ratio

44
Q

What is flying for maximum endurance? What affects it?

A

The maximum amount of time an aircraft can remain in flight for the given amount of fuel on board.

The time is less at higher powers and greater at lower powers

45
Q

When is establishing maximum endurance in flight advisable?

A

When a pilot is requested to hold clear of a control zone

46
Q

Describe the relationship between power and airspeed when flying for maximum endurance

A
47
Q

Describe the relationship between power and airspeed when flying for maximum range

A
48
Q

What is slow flight?

A

The range of airspeed between the maximum endurance speed for a particular aircraft, and a point just above the stall speed for the existing conditions of flight

49
Q

When is slow flight encountered?

A

On take-offs, landings, and recovery from misjudged landings

50
Q

Describe the power and drag curves for slow flight

A
51
Q

What is a stall?

A

A loss of lift and increase of drag that occurs when the critical angle of attack is exceeded. Can occur at any attitude and at any airspeed yet the critical angle of attack remains constant for the same aircraft

52
Q

What is the difference between a spin and spiral?

A

Spins occur when a stall is aggravated by a yaw. The wings are stalled. The airspeed is low and constant

A spiral is a steep descending turn in which airspeed, rate of descent, and wing loading increase rapidly. The airspeed may exceed VNE

53
Q

Why does the TAS increase with altitude?

A

The air density decreases at higher altitudes

54
Q

How does weight affect the stalling speed of an aircraft?

A

With added weight an aircraft must operate at a higher AOA to produce the lift necessary to support that weight. The critical AOA will be reached at a higher airpeed

55
Q

How does the center of gravity affect the stall speed?

A

It the centre of gravity is moved to its most allowable forward position, the aircraft stall speed will increase

56
Q

What will happen to the orientation of the aircraft is the centre of gravity is shifted to its most allowable forward position? What can be said about the aircraft’s weight?

A

The aircraft will have a ose down tendency which must be compensated with back pressure on the control column. This increased downloading on the horizontal tail can be considered an increase in the aircraft’s weight as it acts in the same direction

57
Q

What happens when the centre of gravity moves rearward?

A

The stall speed decreases due to the decreased downloading on the horizontal tail. This should not be used as a method of decreasing stall speed because it makes it harder to recover from a stall

58
Q

At what altitude does ground effect exert an influence?

A

At an altitude no greater than the aircraft’s wing span

59
Q

Is a low or high wing aircraft more affected by ground effect?

A

Low wing

60
Q

How much of a reduction in induced drag will a low wing airplane experience at the moment of take off?

A

about 48%, compared to the induced drag generated at flight altitude

61
Q

What is the effect of density and humidity on aircraft performance?

A

The more dense the air is the better the aircraft performance. The humidity adversely affects the density of the air and thus aircraft performance

62
Q

What generates lift?

A

The pressure differential over the wings

63
Q

What is the intensity of wing tip vortices proportional to? What types of aircraft will produce greater vortices and when?

A

Directly proportional to the weight of the aircraft and inversely proportional to the speed of the aircraft. Heavier, slower aircraft will produce greater vortices during take off and landing at near gross weights and high angles of attack

64
Q

Describe the three categories of aircraft weight

A

Group 1: heavy (max take off weight of 300,000lbs+)

Group 2: medium (max take off weight of 12,500-300,000lbs+)

Group 3: light (take off weight up to 12,500lbs)

65
Q

What are the radar seperations between different categories of aircraft?

A

Heavy behind heavy: 4nm

Medium behind heavy: 5nm

Light behind heavy: 6nm

Light behind medium: 4nm

66

Q

What frequency do ELMs communicate on?

A

121.5Mhz and/or 243.0Mhz

71
Q

How long can ELMs provide continuous operation for?

A

48 hours

72
Q

73
Q

What is included in the ELT pre-flight inspection?

A

Switch is in arm position, check batteries, listen on 121.5 to ensure the ELT is not transmitting

74
Q

How does an ELT sense a crash?

A

It contains a crash activation sensor, or G-switch which is designed to detend the deeleration characteristics of a crash and automatically activate the transmitter

75
Q

How do you turn the ELT on after a crash?

A

Assume the automatic activation feature has failed and place the three position switch in the “On” position as soon as possible. Once it is on, leave it on

76
Q

Where should the ELT be placed for best range?

A

As high as possible on a leel surface with no obstructions between it and the horizon. The antenna should be vertical (and ideally on a piece of metal to extend the transmission range)

77
Q

When can an ELT be tested?

A

Only during the first 5 minutes of any UTC hour, and for no longer than 5 seconds

78
Q

What are the two different emergency classifications?

A

Distress: condition of being threatened by serious and/or imminent danger requiring immediate assistance

Urgency: condition concerning the safety of an aircraft or vehicle, or of some person on board or within sight, which does not require immediate assistance
