RNAV navigation concept is primarily GPS-based. Which option describes this best?

• A. GPS-based navigation
• B. Ground-based VOR navigation
• C. DME navigation
• D. Radar navigation

Answer: (A)

RNAV is navigation defined by flying to and between a sequence of waypoints using position data from satellites rather than depending on individual ground-based radio beacons. Because the position reference comes from satellites, the navigation concept is best described as GPS-based navigation. Ground-based VOR, DME, and radar navigation all rely on signals from ground stations or radar returns, which RNAV moves away from by using satellite positioning to determine where you are and how to get to the next waypoint.
