- Sinônimos
- magnetic compass error
- Definição1
- (1) An error in magnetic compasses caused by acceleration forces acting on the dip-compensating weight when an aircraft is flying in an east-west direction. 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. (2) An error in a bubble sextant caused by mechanical inertia during changes in an aircraft's velocity.
