What is required on all random RNAV routes?

• A. Visual monitoring by pilot
• B. IFR clearance only
• C. No ATC contact required
• D. Radar monitoring by ATC

Answer: (D)

Radar monitoring by ATC is required on random RNAV routes because these routes are defined by RNAV waypoints rather than ground-based navaids, so ATC relies on radar surveillance to determine your exact position and ensure separation from other traffic. While flying IFR, you’ll have an assigned clearance and be in contact with ATC, and they use radar to monitor you on these routes. Visual monitoring by the pilot isn’t the basis for separation on IFR routes, and no ATC contact isn’t allowed, since ATC radar surveillance is what provides the safe separation assurances on these RNAV paths.
