Q

What are two things that should be considered during inspection of a magnetic compass?

A
  1. The fluid must be clear. 2. The housing must be full with no bubbles. 3. The card must be legible and the lubber line intact. 4. The compass should be properly calibrated.

Q

In what way do magmatic fields generated by electrical equipment and steel parts in the airplane effect a magnetic compass?

A

Stray magnetic fields deflect the compass from correct alignment with the earth’s magnetic field.

Q

Who is authorized to apply the range markings to an instrument dial face?

A

The manufacturer or a certificated instrument repair station.

17
Q

What is the purpose of a slippage mark on an instrument glass?

A

To indicate if the glass has moved which could cause incorrect range markings on an instrument that has the range markings painted on the glass.

18
Q

What references should be consulted to determine the proper range markings for aircraft instruments?

A

The aircraft maintenance manual, aircraft flight manual, type certificate data sheet or aircraft specifications.

19
Q

What is the meaning of a yellow arc on an aircraft instrument?

A

A caution or limited flight operation range.

20
Q

What is the reason for “swinging” a compass and how is it accomplished?

A

To compensate for deviations, caused by magnetic fields in the aircraft, by adjusting the compensating magnets.
