- Contexto
- GNSS enables PBN and provides navigation guidance for all phases of flight, from en-route through to precision approach. By providing position information, GNSS enables ADS-B, ADS-C, moving map displays, terrain awareness and warning systems (TAWS) and synthetic vision systems. Emergency Locator Transmitters (ELTs) also use GNSS position data. GNSS also supports a wide variety of precision timing applications. Many States already employ GNSS to deliver improved service to aircraft operators where no conventional systems exist.
- An operable Class A terrain awareness warning system (TAWS) is required for all RNP AR APCH procedures. It is recommended that the TAWS use an altitude that compensates for local pressure and temperature effects (e.g. corrected barometric and GNSS altitude), and includes significant terrain and obstacle data. The flight crew must be cognizant of the required equipment.
