If RNAV-only destinations are planned, which action is prudent?

• A. Diversion
• B. Accept non-RNAV approaches
• C. Proceed with IMC approach
• D. Squawk 7600

Answer: (A)

Planning to fly to RNAV-only destinations means you’re relying on GPS/GNSS for both navigation and the approach. That makes having a diversion plan essential: if the RNAV capability is degraded or unavailable, you need a safe fallback to an alternate airport with conventional navigation facilities or non-RNAV approaches. Without that, you could be left unable to land at the intended airport, which is a significant risk. Diversing to a non-RNAV-capable airport provides a concrete, practical safety margin because it ensures you can complete the flight even when GNSS is unreliable. Accepting non-RNAV approaches at the destination isn’t always feasible since RNAV-only airports may not offer approved non-RNAV procedures. Proceeding with an IMC approach to an RNAV-only destination assumes the existence of an alternative approach path that may not be available. Squawking 7600 indicates a GPS/GNSS failure during flight, not a planning action; it’s an in-flight indication rather than a preventative step.
