What happens if you pass the Final Approach Fix without DME and are below localizer minimums?

If you pass the Final Approach Fix without DME and are below localizer minimums, the appropriate course of action is to execute a go-around. This is due to safety regulations and standard operating procedures that dictate maintaining a safe altitude and ensuring that proper approach criteria are met before continuing to land.

When below localizer minimums, there is an increased risk of being unable to stabilize the approach or meet the required visual references for landing. A go-around is a conservative and safe maneuver that allows the pilot to regain altitude and reassess their approach, ensuring a more controlled and safer landing opportunity. This action is crucial for maintaining safety in flight operations, particularly in challenging approaches or adverse weather conditions.
