First U.S. Ground-Based Augmentation System Is Operational
United Airlines and Honeywell celebrated a satellite navigation milestone September 28 when they received operational approval for a ground-based augmentation system (GBAS using Honeywell’s SmartPath SLS-4000) installed at Newark Liberty International Airport (EWR), clearing the way for United to begin regular passenger flights in the U.S. using this technology.
United Airlines will primarily fly its GBAS capable Boeing 737-800 and -900 model aircraft into EWR. A United Boeing 787 Dreamliner also made its first GBAS landing at Newark on October 10. GBAS provides digital guidance for precision approaches using a differential global positioning system for aircraft equipped with a multi-mode receiver or an integrated navigation receiver.
The Honeywell GBAS SmartPath system is approved for precision approach operations down to 200 feet.
