1. Space-Based ADS-B for Reduced Oceanic Separation
The FAA is developing a business case to establish reduced separation requirements for airplanes flying in U.S.-controlled oceanic airspace. A government-industry body, the Enhanced Surveillance Task Group (ESTG) has determined that the way to do this is by introducing space-based ADS-B into oceanic airspace controlled by the FAA. The questions now — how to pay for that and how to prove it would be effective, considering the mixed avionics equipage status of aircraft flying in U.S. oceanic airspace.
