What should be the indication on the magnetic compass as you roll into a standard rate turn to the right from a northerly heading in the northern hemisphere?
a) the compass will indicate the approximate correct magnetic heading if the roll into the turn is smooth. b) the compass will remain on east for a short time, then gradually catch up to the magnetic heading of the aircraft. c) the compass will initially indicate a turn to the left.

The compass will indicate a turn to the left.

Explanation:

The magnetic compass has a needle pointing towards north. It is used for navigation and it shows direction with respect to the geographical cardinal direction.

As we move to the right of the northerly heading in northern Hemisphere, the direction of needle will move towards left but with a faster rate as now the direction of north is no his left.

This shows the compass if following its direction properly.

it would be c. predictability
