The Chicago Trials, then, could be a first step In validation of GPS for civil aviation. Participants at O'Hare have a much bigger vision of GNSS for the future. We want to explore technologies that will bring down the cost of flying for everyone, from commercial carriers to private pilots. In addition, airlines see GNSS providing the capability for precision instrument approaches at an airports, improved airport ground operations and improved departure guidance. This will allow reduced separation between aircraft and random routing of aircraft without compromising safety.
More aircraft can use optimal routes, with significant fuel savings.
Better access to airports. In either direction for both arrivals and departures. Standardized Instrument approaches based on GNSS decreases pilot training and certification costs. They result In Improved access to thousands of airports and runways used by commuters and general aviation aircraft. Curved approaches to ILS-equipped airports also are possible.
