Abstract : Development and flight results are presented from a program to test feasibility of using an inertial system to provide the aircraft position reference for performing basic flight inspection of ILS and VORTAC facilities. An Inertial Locator Equipment was designed, constructed and integrated into the SEAL flight inspection system. Numerous flights were made at both the Bedford Flight Facility of the M. I. T. Charles Stark Draper Laboratory and at NAFEC in Atlantic City, New Jersey. Methods for the utilization of externally derived information (post-landing check point for ILS mode and DME range for VORTAC mode) were incorporated in the system. The use of the corrected data mode in both types of inspection missions demonstrated improvement over real-time inertial performance, yielding acceptable results. (Author)
