RNAV (Area Navigation)

RNAV (Area Navigation) is a method of navigation that allows aircraft to fly on any desired flight path within the coverage of ground- or space-based navigation aids, or within the limits of onboard systems. Unlike conventional navigation that requires flying directly to or from ground-based navaids, RNAV enables more efficient routing.

• Uses GPS, DME/DME, VOR/DME, or INS inputs
• Enables direct routing and fuel savings
• Required for many modern SIDs and STARs
• RNAV approaches (e.g., RNAV GPS) are replacing traditional procedures worldwide
