A free directional gyro has no Earth-rate correction or mechanical drift. At P (60°N 030°W), the true heading is 090° and the gyro heading is 000°. After 1 h 30 min, at Q (62°N 010°W), the true heading is 095°. Use mean latitude 61° for both Earth-rate and transport-wander calculations and an Earth rotation rate of 15°/h. What is the gyro heading at Q, rounded to the nearest degree? - ATPL Question Bank In English
