Summary A Category III Precision instrument landing system (ILS) approach requires 18 ft horizontal and 2.2 ft vertical accuracy at 50 ft above the ground, and is probably the most severe real-time flight control task. if the Global Positioning System in differential mode (DGPS), integrated with inertial, barometric and/or radar altitude sensors, and supported by real-time fault tolerant computing, is to be approved by the ICAO and FAA for automatic landings, additional requirements of availability and integrity at the (1–10−9) level must be met for civil aviation. Onboard real-time health management requires advances in on-board processing, memory, and communications. Technical feasibility was established as part of the DARPA Pilot’s Associate project, but it did not function in real-time. To minimize cost and risk of migrating GSE diagnostic systems to the onboard environment, use of the Rockwell Science Center developed “Simulation Analysis of Distributed Systems (SADS)” is being recommended to ensure adequate real-time performance.
