RNAV is a navigation method known as

• A. The four fundamental risk elements in aviation.
• B. See radio magnetic indicator.
• C. See area navigation.
• D. The final adjustment and alignment of an aircraft.

Answer: (C)

RNAV is area navigation. It’s a method that allows you to fly a desired flight path on the basis of waypoints rather than being tied to a specific ground-based navaid. With RNAV, your position is determined by onboard sensors (such as GPS, inertial sensors, or baro-aiding) and you can navigate directly to waypoints, follow routes composed of straight lines, arcs, or combinations, and use more flexible approaches. This enables more efficient, precise routes and procedures that aren’t limited to VOR/DME alignments. The other options describe unrelated concepts (risk elements, an indicator name, or aircraft alignment), so they don’t fit RNAV.
