An aircraft is "homing" to a radio beacon whilst maintaining a relative bearing of zero.If the magnetic heading decreases, the aircraft is experiencing:

1) The chart in question is of the polar stereographic type with its grid parallel to the zero meridian, and Grid North in the direction of the North geographic pole. The gyro does not comprise a rate correction device. The gyro-magnetic compass of an aircraft standing at an aerodrome located at 59057'N 010030'E is switched to free gyro mode at 14.00 UTC, with gyro North being aligned with Grid North and the gyro heading reading 1200. A technical problem delays take off until 16.30 UTC. The gyro, whose mechanical precession is zero, was not reset prior to take off. The error (E) at the time of alignment on this runway will be:

2) An aircraft is "homing" to a radio beacon whilst maintaining a relative bearing of zero.If the magnetic heading decreases, the aircraft is experiencing:

3) Deviation due to coefficient A is mainly caused by:

4) If the Compass Heading is 265 degree, variation is 33 degrees West and deviation is 3 degree East, what is True Heading?

5) In preventive RA include?
