Which statement describes a nonGNSS strategy for KGWO when outside routing limitations?

• A. KGWO SQS HLI then as filed
• B. KGWO SQS IGB then as filed
• C. Direct to SQS
• D. Cancel departure

Answer: (B)

NonGNSS navigation relies on conventional navigation aids and published fixes so you can stay on a safe, properly sequenced path even when GPS isn’t available or allowed. For KGWO, the recommended non-GNSS route uses a defined sequence that can be identified without satellites: fly to SQS, then to IGB, and continue as filed. This ordering ensures you reach a fix that is compatible with the filed route and allows you to rejoin the original plan after the non-GNSS segment, keeping the track, constraints, and airspace logic intact. Going directly to SQS omits the necessary rejoin point and can leave you off the intended path, while other fixes may not align with the non-GNSS plan or could unnecessarily cancel the departure.
