Deceleration error

Deceleration Error

Deceleration Error is a type of compass error that occurs when an aircraft slows down while flying on an easterly or westerly course. This causes the compass card to rotate towards the south. The rotation happens because the compass card is influenced by the earth’s magnetic field, and a reduction in speed affects this field’s impact on the compass. Deceleration error can cause incorrect readings, leading to inaccurate navigation and potentially hazardous flying conditions. Pilots must be aware of this error and take measures to counter its effects to ensure flight safety.
