The Jan. 1, 2020 effective date requiring ADS-B Out for operating in certain U.S. airspace applies to foreign-registered aircraft as well as N-numbered aircraft, the FAA stressed in its latest edition of FAA SatNav News. In addition, the agency said, ADS-B Out equipment on non-U.S.-registered aircraft must comply with the same performance requirements laid out for N-numbered aircraft in FAR 91.225 and 91.227.
The publication also contained other ADS-B reminders and clarifications. For example, operators are required to have ADS-B transmitting at all times, including while on the surface of the airport. “By regularly broadcasting position, velocity, and identification information to ATC and other aircraft, situational awareness is improved on the ground and in the air.” Also, GPS receivers used as an ADS-B position source must be compatible—have “approved pairing”—with the installed ADS-B transmitter.
Portable ADS-B Out units are not authorized for several reasons, but mainly because they would not meet the applicable TSO C166b or C154c for installed equipment that is required on aircraft with a standard airworthiness certificate.
Since virtually all business aircraft will fly in Class A airspace, those operators will need a 1090-MHz extended squitter (ES) transmitter. They will also need a 1090ES ADS-B Out transmitter for operations outside U.S. airspace where ADS-B is required.
