What action is typically taken if an aircraft reaches the VDP and the runway is not in sight?

When an aircraft reaches the Visual Descent Point (VDP) and the runway is not in sight, the appropriate action is to execute a missed approach. The VDP marks a point during the approach where a visual reference to the runway should be established to safely complete the landing. If the pilot does not see the runway at this point, initiating a missed approach ensures safety by allowing the aircraft to climb away from potentially hazardous terrain or obstacles.

Executing a missed approach is a standard safety procedure, as it allows the pilot to follow a predefined flight path to safely reconfigure for another attempt at landing or to divert to an alternate airport. This procedure typically involves climbing to a specified altitude and following an established missed approach procedure, thereby prioritizing the safety of the aircraft and crew. Thus, performing a missed approach is critical to maintaining safety under these circumstances.
