Both aircraft and ships use both magnetic and gyro-type compasses. it is a tradition if not a law that both types be carried. The Gyro-direction indicators in light planes has to be recalibrated periodically during maneuvers, this does not apply to the magnetic type. Ships, also use both types.

A Magnetic compass goes well with with a fine, Mahogany helm on a brass steering stand!
