A

30 days

2
Q

When making an airborne VOR check using a dual VOR system, what is the maximum allowable difference between the two?

A

4 degrees between the two indicated bearings of a VOR

3
Q

If in level flight, it becomes necessary to use an alternate source of static pressure, which instrument indications will vary and how will they vary?

A

The altimeter will read higher than normal, airspeed greater than normal, and the VSI will momentarily show a climb.

4
Q

How will the magnetic compass react when rolling into a standard rate turn to the right from an easterly heading in the N hemisphere?

A

The compass will indicate an approximate correct heading if the roll into the turn is smooth

5
Q

How will the magnetic compass react when rolling into a standard rate turn to the right from an southerly heading in the N hemisphere?

A

The compass will indicate a faster turn to the right than what is actually occurring

6
Q

How will the magnetic compass react when rolling into a standard rate turn to the left from an southerly heading in the N hemisphere?

A

The compass will indicate a faster turn to the left than what is actually occuring

7
Q

How will the magnetic compass react when rolling into a standard rate turn to the right from an northerly heading in the N hemisphere?

A

The compass will initially indicate a turn to the left before correcting to the right

8
Q

The rate of turn at any airspeed is dependent upon

A

The horizontal lift component

9
Q

What is the relationship between centrifugal force and the horizontal lift component in a coordinated turn?

A

Horizontal lift and centrifugal force are equal

10
Q

During a skidding turn to the right, what is the relationship between the component of lift, centrifugal force, and the load factor?

A

Centrifugal force is greater than horizontal lift and the load factor is increased

11
Q

What force causes an airplane to turn?

A

Horizontal lift component

12
Q

Which instrument indicates the quality of a turn?

A

Ball of the turn coordinator

13
Q

During a constant bank level turn, what effect would an increase in airspeed have on the rate and radius of the turn?

A

Rate of turn would decrease, and radius would increase

14
Q

Conditions that determine the pitch attitude required to maintain level flight are

A

airspeed, air density, wing design, and angle of attack

15
Q

Rate of turn can be increased and the radius of a turn decreased by

A

decreasing the airspeed and increasing the bank

16
Q

The primary reason the angle of attack must be increased to maintain a constant altitude during a coordinated turn is because the

A

vertical lift component has decreased as the result of the bank

17
Q

What would the VSI indicate during entry into a 500 FPM descent from level flight if the static ports were iced over?

A

The VSI pointer would remain at zero regardless of the actual descent rate

18
Q

If the pitot tube was clogged during flight, which instrument(s) would be affected?

A

The airspeed indicator only.

19
Q

At an altitude of 6,500 feet MSL, the current altimeter setting is 30.42” Hg. The pressure altitude would approximately be

A

6,000 feet.

Every 0.01” Hg is 10 feet,
30.42-29.92 = .50” Hg
50 x 10’ = 500’
6,500 - 500 = 6,000’

20
Q

The pressure altitude at a given location is indicated on the altimeter after the altimeter is set to

A

29.92”Hg

21
Q

If the outside air temperature increases during a flight at constant power and at a constant indicated altitude, the true airspeed will

A

increase and the true altitude will increase

22
Q

What indications are displayed by the miniature airplane in the turn coordinator?

A

Rate of roll and Rate of turn

23
Q

During normal operation of a vacuum driven attitude indicator, what attitude indication should you see when rolling out from a 180 degree skidding turn to straight-and-level coordinated flight?

A

The miniature aircraft shows a turn in the direction opposite of the skid.

Sustained turns induce an error into the attitude indicator that is opposite the sustained turn; the longer the turn takes, the larger the induced error

24
Q

During normal coordinated turns, what error due to precession should you observe when rolling out to straight and level from a 180 degree steep turn to the right?

A

The miniature aircraft would show a slight turn indication to the left

25
Q

What information does a Mach meter present?

A

The ration of aircraft true airspeed to the speed of sound

26
Q

Error in both pitch and bank indication on an attitude indicator are usually at a maximum as the aircraft rolls out of a

A

180 degree turn

27
Q

If a 180 degree steep turn is made to the right and the aircraft is rolled out to straight-and-level flight by visual references, the attitude indicator

A

may show a slight climb and turn

28
Q

One characteristic that a properly functioning gyro depends upon for operation is the

A

resistance to deflection of the spinning wheel or disc

29
Q

How should you preflight check the altimeter prior to an IFR flight?

A

Set the altimeter to the current altimeter setting. The indication should be within 75 feet of the actual elevation for acceptable accuracy.

30
Q

When airspeed is decreased in a turn, what must be done to maintain level flight?

A

Decrease the angle of bank and/or increase the angle of attack

31
Q

The primary reason the pitch attitude must be increased, to maintain a constant altitude during a coordinated turn, is because the

A

vertical component of lift has decreased as the result of the bank

32
Q

When checking the sensitivity of a VOR receiver, the number of degrees in course changes as the OBS is rotated to move the CDI from center to the last dot on either side should be between

A

10 degrees and 12 degrees

33
Q

If in level flight and it becomes necessary to use an alternate source of static pressure vented inside the airplane, what should the pilot expect to see

A

The vertical speed indicator to momentarily show a climb

The altimeter indicates a slightly higher altitude than actual

The airspeed indicator indicates an airspeed greater than actual

36
Q

How should the pilot make a VOR receiver check when the aircraft is located on the designated checkpoint on the airport surface?

A

Set the OBS on the designated radial. The CDI must center within +/- 4 degrees of that radial with a FROM indication

42
Q

What wind condition prolongs the hazards of wake turbulence on a runway for the longest time?

A

Light quartering tailwind

43
Q

Wake turbulence is near maximum behind a jet transport after takeoff because

A

of the high angle of attack and high gross weight

44
Q

What effect would a light crosswind have on vortex behavior?

46
Q

If both the ram air input and drain hole of the pitot system are blocked, what airspeed indication can be expected if large power changes are made?

47
Q

If both the ram air input and drain hole of the pitot system are blocked, what would you observe on the airspeed indicator when power is applied and a climb is initiated out of severe icing conditions

A

No change would occur during power input, but after a climb rate is established the airspeed indicator would show an increasing indicated airspeed.
