Abstract
A pilot is maneuvering an aircraft on a ground surface, such as a runway or taxiway. On a cockpit display, the pilot sees a scaled aircraft symbol overlaying a moving map on a cockpit display. The aircraft symbol represents the aircraft, while the moving map represents the ground surface on which the aircraft is located. The aircraft symbol depicts its nose gear and main gear with respect to the ground surface. The nose gear on the aircraft symbol rotates based on tiller angle. The cockpit display also shows edge guidance lines that allow the pilot to line up the main gear, while providing a margin of safety. Predictive symbology also overlays the moving map to provide an indication of whether the aircraft can safely turn on the ground surface.
