Qantas Airlines has received approval from the Australian Civil Aviation Safety Authority (CASA) to use the Honeywell SmartPath ground-based augmentation system (GBAS) at Sydney International Airport for satellite-based landings with its Airbus A380s. The SmartPath GBAS supports precision approach and landings using GPS satellite data and transmits digital guidance signals to aircraft systems. The first A380 landing using GBAS occurred during a test flight in Sydney in June 2007. Honeywell provides the FMS and 11 other products and systems for the Airbus A380.

Honeywell has worked on the development of SmartPath with Airservices Australia, which has used GBAS technology since 1999 and operated the Honeywell SmartPath GBAS ground station in Sydney since November 2006. Qantas has already gained approval to fly GBAS approaches with its Boeing 737s and has recorded more than 1,600 GBAS landings in Sydney so far.
