You plan to fly from point A (60°N 01 0°E) to point B (60°N 020°E). The Gyro North of the gyro compass, assumed to be operating perfectly, with no rate correction device, is aligned with the True North of point A. The constant gyro heading to be followed when starting from A given that the flight time scheduled is 1 hr 30 min with a zero wind, is equal to:

• 066°

• 080°

• 076°

• 085°
