In-Flight Detection of Errors for Enhanced Aircraft Flight Safety Using DTED with GPS and Radar Altimeter

摘要

This paper describes an integrated architecture using digital terrain elevation data(DTED)with kinematic GPS(KGPS)and a radar altimeter. Flight testing was performed to assess the feasibility of enhanced flight safety. Reasons for enhanced flight safety are twofold: (1)the and hoc integration of terrain elevation data into the cockpit could conceivably create scenarios that would lead to accidents because the cockpit display is quite realistic, and(2)controlled flight into terrain(CFIT)is reduced.
