To help business aircraft operators cope with new Rnav routes and procedures as of September 1, the FAA is developing a Web-based RAIM (receiver autonomous integrity monitor) prediction service that will be made available for general use by flight crews, according to NBAA.
The GPS approach is out, and the Rnav approach is in. That’s because many pilots tend to think of GPS as a land-based navaid like a VOR, NDB or as a part of an ILS, and experts believe that thinking is misleading. More precisely, it’s the FMS in the airplane that allows the actual instrument approach to be flown.
Recent guidance from the FAA advises pilots that beginning next January 20, when RVSM is scheduled to be implemented in the U.S., ATC will start using the flight-plan equipment block information to issue or deny clearance into RVSM airspace. For both FAA and ICAO flight plans, the letter “W” will signify that an operator has RVSM authorization. Questions about all aspects of RVSM can be directed to the FAA at (202) 863-2175.
In the runup to the planned January 20 implementation of reduced vertical separation minimums (RVSM) in the U.S., Canada, South America and Mexico, the FAA has released new guidance documents to assist operators seeking to comply with the requirements of the new operating rules.
The vision of a future air navigation system developed by the International Civil Aviation Organization (ICAO) at the beginning of the 1990s has taken a long time to materialize. But the gradual execution of some of the main elements suggests the future may finally be at hand.
Effective January 5, when filing an FAA flight plan (with the exception of filing through DUATS and flight service stations), RVSM-compliant operators are expected to file “/Q” (RVSM with a FMS or GPS) or “/W” (RVSM without FMS and GPS), as appropriate, for flight in RVSM airspace (between FL290 and FL410 inclusive).
Latin America adopted reduced vertical separation minimums (RVSM) on January 20, along with the rest of the Americas, and the transition to date in Brazil has been relatively smooth, according to national officials.
“There were no major problems on January 20,” said Saulo Jose da Silva of Brazil’s Department of Air Traffic Control.
To help business aircraft operators cope with new Rnav routes and procedures that took effect last month, the FAA is developing a Web-based RAIM (receiver autonomous integrity monitor) prediction service that will be made available for general use by flight crews, according to NBAA.
Effective September 1, operators are required to use a new set of flight plan aircraft equipment suffixes to indicate advanced navigation capabilities. Pilots must use J, K, L or a newly defined Q to specify advanced Rnav and RVSM capabilities. They should continue to use a W to indicate RVSM capability only. The revised list also contains significant changes to the definitions of E and F.
