Certification and Operational Performance of GPS-Based Landing Systems

D. Alexander Stratton, Christopher Douglas, Russell Gollnick and Ray Cole

Abstract:	The paper discusses the certification and early operational experiences with the world’s first two Local Area Augmentation System (LAAS) certified aircraft, a Federal Express Boeing 727-200 and a Rockwell Collins Sabreliner 65. Federal Express and Collins certified these aircraft under a government-industry partnership program. Both installations are based on the Rockwell Collins GNLU-930 Multi-Mode Receiver (MMR). Category I (CAT I) Instrument Flight Rule (IFR) operational approvals are based on interim standards developed by RTCA ([1-4]). The aircraft are operated under special operational specification approvals. On-going improvements planned for the system include migration to the final RTCA and ICAO standards for Category I, II, and III. The paper describes the goals and certification approach, the performance testing of the GNLU-930, flight test results from the certification and data acquisition program, and feedback on the performance of the system from operational users.
