Which statement best describes Area Navigation (RNAV)?

• A. Allows a pilot to fly a selected course to a predetermined point without the need to overfly ground-based navigation facilities, by using waypoints.
• B. Requires overflying VOR/DME stations.
• C. Depends exclusively on NDB signals.
• D. Is limited to en route navigation above 30,000 feet.

Answer: (A)

Area Navigation lets you fly a path defined by waypoints rather than by following ground-based navaids. With RNAV, your onboard navigation system determines your position and guides you from one predetermined point to another, so you can fly directly to a waypoint even if there isn’t a VOR or other ground facility in the same track. This capability isn’t tied to overflying specific stations; it enables more direct routing and flexible use of airspace, and it’s commonly supported by GPS-based systems (with other approved sensors like inertial navigation also contributing). It can be used for enroute and terminal operations and isn’t limited to a particular altitude. That makes the described statement the best fit for what RNAV is. The other options imply dependencies on ground-based facilities, a sole reliance on NDB signals, or a height restriction, none of which accurately describe RNAV.
