During a GPS approach, what allows you to continue the approach to the missed approach point?

• A. When GPS APPR appears at the bottom of the NAV source info block on the PFD.
• B. When the autopilot engages the approach mode
• C. When the GPS is in standby
• D. When the FMS shows green

Answer: (A)

The important thing here is that the GPS approach mode is actively guiding you along the published approach. When the GPS shows APPR in the NAV source block at the bottom of the PFD, it means the GPS has loaded the current approach and is providing the final approach guidance to the Missed Approach Point. With this mode active, you can continue along the published path all the way to MAP, and the system will handle the transition to a missed approach if you haven’t met the requirements by that point.

Autopilot in approach mode can help you fly the segment, but simply engaging autopilot isn’t the indicator that the GPS is actively guiding the approach. GPS guidance being in standby disables navigation guidance, and a generic green indication on an FMS isn’t a universal cue that the GPS approach is active.
