What is a common consequence of not executing a missed approach when necessary?

When a pilot fails to execute a missed approach when required, one of the most serious consequences is the increased risk of a potential collision with other aircraft. During the approach phase of flight, precision and adherence to procedure are critical. The missed approach procedure is designed to ensure safety by directing an aircraft away from the runway when a landing cannot be safely completed, whether due to obstacles, poor visibility, or other hazards.

If a pilot disregards this procedure, they may inadvertently descend into an area where other aircraft are operating or maneuvering, thus increasing the chances of a mid-air collision. This potential for collision highlights the necessity of following established protocols during all phases of flight to uphold safety standards in aviation.

Other factors, such as visibility conditions or fuel efficiency, would not typically improve when a missed approach is not performed; instead, they could lead to dangerous situations. Regaining altitude above the Instrument Landing System (ILS) is also inappropriate because it contradicts the purpose of the missed approach, which should be executed when safe landing is not achievable.
