FAA trusts ADS-C for minimum separation standards in New York Oceanic FIR

摘要

South of Gander Oceanic is the New York Oceanic Flight Information Region (FIR), a responsibility of the US Federal Aviation Administration (FAA). It does not have the same capabilities for reduced separation that Nav Canada and NATS offer in their oceanic FIRs and uses a system similar to one they have just replaced, based on ADS-C relayed via FANS datalinks. The FAA is thoroughly familiar with the use of ground-based ADS-B for surveillance, but has not deployed it in oceanic areas. Its Capital Investment Plan sets out the agency's plans to deploy ground-network-based ADS-B surveillance gradually, replacing secondary surveillance radar over land and in coastal areas beginning in 2020. The FAA already uses it extensively in the Gulf of Mexico for surveillance of low-level oil-support helicopter operations.
