Heading Indicators
Heading Indicators are instruments used in aircraft to display the aircraft's heading with respect to magnetic north. They are typically gyroscopic instruments that use the principle of rigidity in space to maintain a constant heading reference. The heading indicator is an essential instrument for pilots, as it provides a stable and reliable reference for navigation and instrument flying. However, it is subject to errors due to precession and other factors, and must be periodically calibrated to ensure accuracy.
