What does a compass indicate when the aircraft accelerates while turning?

• A. Turn to the east
• B. Turn to the north
• C. Turn to the south
• D. Turn to the west

Answer: (B)

When an aircraft accelerates while turning, the compass indicates a turn to the north due to a phenomenon known as magnetic dip or compass turning error. During a turn, centrifugal force causes a deviation in the magnetic compass reading. When the aircraft is accelerating on a northerly heading, the compass will lag, resulting in a temporary indication that suggests a turn towards the north even if the aircraft is not actually moving in that direction. Understanding this behavior is crucial for pilots since it highlights the importance of vigilance with compass readings during maneuvers. Correctly interpreting how the compass behaves during various flight conditions ensures navigational accuracy, which is vital for flight safety and efficiency.
