Question

The relative acceleration of a vehicle moving with respect to a rotating Earth can be divided into three parts.

(a) True

(b) False

The question was posed to me during a job interview.

My question is taken from Vertical & Heading References topic in division Air Data Systems, Altitude and Heading Reference of Avionics

Answer 1

Correct choice is (a) True

Best explanation: When a vehicle moves at a velocity relative to the rotating Earth, the inertial acceleration can be divided into three parts: Acceleration relative to the surface of Earth, Coriolis acceleration caused by rotation of Earth, and a correction that depends on the coordinate frame in which the gyro is constrained.
