1.	Inertial heading references are better than a magnetic compass.(a) True(b) FalseI had been asked this question in an interview.My enquiry is from Vertical & Heading References in chapter Air Data Systems, Altitude and Heading Reference of Avionics
Answer» RIGHT choice is (a) True To elaborate: The best airborne heading references are the inertial navigators. Less expensive, smaller and less accurate references are those that DEPEND on the EARTH’s MAGNETIC field, those that depend on the use of gyroscopes to retain a preset azimuth, and those that use subinertial GYROS to maintain a three axis reference.
