Under what conditions can a pilot initiate a missed approach?

A pilot can initiate a missed approach under specific conditions that primarily revolve around the ability to establish visual contact with the runway environment and instructions from air traffic control (ATC). When flying an approach, if a pilot cannot see the required visual cues that indicate they are in a position to land safely, it is necessary to execute a missed approach to ensure safety.

This approach procedure is crucial, particularly in low visibility conditions. Additionally, if ATC instructs a pilot to climb and not land, the pilot must follow that directive. The choice reflects the importance of situational awareness and communication with ATC in ensuring a safe flying environment.

In contrast, the visibility of runway lights alone is not a sufficient condition for a missed approach, as the pilot might have other visual references. Running low on fuel can certainly lead to critical decisions, but it is not an approved reason to initiate a missed approach since safety and the ability to see the runway take precedence. Lastly, while receiving radar vectors can aid in navigation and sequencing, it is not a prerequisite for a missed approach. The ability to establish visual contact or follow ATC instructions remains the primary factors.
