When do you know to go missed on a LOC approach?

• A. Altitude or Aircraft Speed
• B. Visibility or Weather Conditions
• C. DME or Time
• D. Control Tower Instructions

Answer: (C)

Going missed on a LOC (Localizer) approach is typically based on specific criteria relating to distance from the airport or the elapsed time during the approach. The decision often hinges on Distance Measuring Equipment (DME) readings, which help determine how far the aircraft is from the runway threshold, or on timing if DME is not available or not being used effectively. If the aircraft has not established visual contact with the runway environment or met the required decision altitude by the predetermined DME or timing, a missed approach is warranted for safety reasons. In this scenario, the choice connects directly to the procedures and regulations set forth for executing approaches safely, allowing pilots to maintain situational awareness of their proximity to the airport and make informed decisions about continuing the approach or executing a missed approach. Using DME or time ensures that the pilot has concrete metrics to guide their decision-making process rather than relying solely on subjective criteria.
