RNAV

from Wikipedia, the free encyclopedia

RNAV (Engl. Area navigation , primitive navigation Random , dt. RNAV ), referred to in the aviation a navigation method for IFR flights , the route via freely selectable waypoints sets (waypoints). Fixed radio beacons on the ground no longer have to be flown to, as only the geographical coordinates are determined for the waypoints. The optimized routes of the RNAV allow more flexibility, a more effective use of airspace , a higher airspace capacity, less effort for changes (construction costs etc.) and thus also a reduction in costs.

The technical implementation takes place with the help of various technical systems. In addition to VOR / DME , DME / DME and INS / IRS , GNSS is used. This enables inexpensive and precise navigation.

B-RNAV (Basic-RNAV) requires a position determination of ± 5 NM , (i.e. RNP -5), P-RNAV (Precision-RNAV) of ± 1 NM in 95% of the flight time.
