Q

What should be the indication on the magnetic compass as you roll into a standard rate turn to the right from an easterly heading in the Northern Hemisphere?

A

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

Q

What should be the indication on the magnetic compass as you roll into a standard rate turn to the right from a south heading in the Northern Hemisphere?

A

The compass will indicate a turn to the right, but at a faster rate than is actually occurring.

Q

While recovering from an unusual flight attitude without the aid of the attitude indicator, approximate level pitch attitude is reached when the

Q

Which is the correct sequence for recovery from a spiraling, nose-low, increasing airspeed, unusual flight attitude?

Q

What is the purpose of the kerosene within the housing of the magnetic compass?

A

To allow the disc to spin freely. Also, kerosine doesn’t freeze unless in extremely low temps.

17
Q

What is the purpose of the diaphragm within the housing of the magnetic compass?

A

It allows the fluid to expand and contract with changes in temp and pressure.

18
Q

What is located within the magnetic compass that aligns with magnetic north?

A

Compass Needle

19
Q

Describe magnetic variation. How does a pilot compensate for it?

A

the difference between magnetic and true north. + West, - East variation

20
Q

Describe magnetic deviation. How does a pilot compensate for it?

A

Interference from other instruments in the aircraft. Fix it by checking the compass deviation card and changing your heading appropriately

21
Q

How do you preflight the magnetic compass?

A

check compass card and ensure compass is moving freely and matching heading indicator

22
Q

What is a agonic line?

A

Line that connects all points on earth where the magnetic variation is 0

23
Q

Explain northerly turning error

A

If turning from a north heading the compass will “lag” in the turn.

24
Q

On what headings are Acceleration/Deceleration errors most apparent?

A

Easterly and Westerly

25
What is the formula for determining standard bank angle without the turn coordinator?
Divide your airspeed by 10 and add one-half the result
26
In a timed standard rate turn, how long does it take to turn 180 degrees?
1 minute
27
Explain how a pilot would recognize the failure of the attitude indicator during instrument flight.
G5 will show a red X
28
If part or all of the pitot-static instruments exhibited abnormal operation in flight, what could a pilot do about this?
Use alternate static air
29
Explain how a pilot would compensate for the loss of the Attitude Indicator AND the Directional Gyro in Partial Panel flight? (Both have failed at the same time)
use other turn and pitch coordinators
30
Describe how to recover from a nose low high bank angle turn unusual attitude to the left?
pull power, pitch up, level wings
