In an ideal spherical-Earth, zero-wind model, fly from A (60°N 010°E) to B (60°N 020°E) in 1 h 30 min at constant TAS. A locally level, perfectly operating directional gyro is initially aligned with true north at A and has no Earth-rate correction or slaving. Approximately which constant gyro heading should be flown, to the nearest degree? - ATPL Question Bank In English
