Слайд 3Compass Errors - Variation
The difference between true and magnetic north
Aeronautical charts

referenced to true
Runways aligned with magnetic
Variation needs to be taken into consideration

Слайд 4Magnetism
Magnet is a piece of metal containing iron that has a

north and south pole which attracts magnetic flux
The earth acts as a giant magnet, so a magnet can be aligned with the earths flux fields
Magnet floats in kerosene fluid and is always trying to stay with magnetic north
Airplane pivots around the compass
Pilot sees headings as etched into the card

Слайд 5Compass Errors - Deviation
Any error caused by a magnetic field other

than the earths
This could be a battery, magneto, alternator, or other electromagnetic disturbance
When a mechanic aligns the aircraft with known magnetic headings, he can denote deviation

Слайд 7Magnetic Dip
Occurs when lines of flux dip into the earth over

the poles
Compass has a dip compensating weight
Weight is the cause of northerly turning errors
Also the cause of acceleration errors
