What is the primary reason to execute a missed approach?

The primary reason to execute a missed approach is the arrival at the Missed Approach Point (MAP). The MAP is a defined point during the approach procedure where the pilot must decide whether to continue to land or to execute a missed approach if the required visual references are not in sight. This decision is critical because it ensures that the pilot is making a safety-oriented choice based on the current conditions and altitude at that specific moment during the approach.

When a pilot reaches the MAP and does not see the runway or the required visual references, they must follow the established missed approach procedure to safely climb away from the approach path and navigate toward a safe altitude, often preparing for a second attempt or diverting to an alternate airport. This action prioritizes safety and compliance with approach procedures.

While weather conditions, inadequate approach lighting, and aircraft configuration are factors that can influence the decision to execute a missed approach, they do not represent the primary reason. A missed approach is fundamentally tied to the decision made upon reaching the MAP, emphasizing the importance of maintaining situational awareness and adhering to procedural guidelines during instrument approaches.
