acceleration error
- Sinônimos
- magnetic compass error
- Definição1

- Definição3
- A magnetic compass error apparent when the aircraft accelerates while flying on an easterly or westerly heading, causing the compass card to rotate toward North.

- Nota adicional1
- In the Northern Hemisphere, when the aircraft accelerates in an east-west direction the compass indicates the aircraft is turning north; it indicates south when decelerating on these headings. The error occurs because the magnet is being pivoted and the point of the pivot and the center of gravity are not coinciding. The errors are in the opposite direction if the compass is correctly decompensated for operations in the Southern Hemisphere.
