Magnetic Compass
Deviation error of the magnetic compass is caused by
certain metals and electrical systems within the aircraft.
The magnetic compass is
self-powered
In the Northern Hemisphere, the magnetic compass will normally indicate a turn toward the south when
the aircraft is decelerated while on a west heading.
On a turn from a northerly heading the compass will:
lags behind the airplane
On a turn from south
The compass exaggerates the rate of turn.
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?
The compass will indicate a turn to the right, but at a faster rate than is actually occurring.
At the beginning of a turn from a northerly heading:
The compass will show a turn in the opposite direction.
The only north seeking instrument in a typical training airplane is:
The magnetic compass.
In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn toward the east if
a left turn is entered from a north heading.
In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn toward the west if
a right turn is entered from a north heading.
In the Northern Hemisphere, a magnetic compass will normally indicate a turn toward the north if
an aircraft is accelerated while on an east or west heading.
In the Northern Hemisphere, if an aircraft is accelerated or decelerated, the magnetic compass will normally indicate
correctly when on a north or south heading.
Deviation in a magnetic compass is caused by the
magnetic fields within the aircraft distorting the lines of magnetic force.
The angular difference between true north and magnetic north is
magnetic variation
There is no acceleration/deceleration error on a heading of:
north or south
During flight, when are the indications of a magnetic compass accurate?
only in straight-and-level flight
