022-03 - Magnetism - Direct reading compass and flux valve

The magnetic dip at any point on the Earth`s surface is the angle:

• made by a compass needle with the horizontal.

• between the horizontal component of the magnetic field and true north direction.

• made by a compass needle with the local vertical.

• made by a compass needle during a steady turn.

An aircraft in the northern hemisphere makes an accurate rate one turn to the right. If the initial heading was 330°, after 30 seconds of the turn the direct reading magnetic compass should read:

• less than 060°.

• more or less than 060° depending on the pendulous suspension used.

• 060°.

• more than 060°.

A pilot wishes to turn left on to a northerly heading with 10° bank at a latitude of 50° North. Using a direct reading compass, in order to achieve this he must stop the turn on an approximate heading of:

• 030

• 355

• 330

• 015

In the northern hemisphere, accelerating in an easterly direction, a direct reading magnetic compass indicates:

• an apparent turn to the north.

• no apparent turn.

• an apparent turn to the south.

• no turn.

Deviation on the standby compass is..

• zero on the magnetic Equator.

• positive if the Compass North is to the west of Magnetic North.

• dependent on the heading of the aircraft.

• independent of the latitude of the aircraft’s position.
