What should be checked before executing a go-around if the runway is not visible?

When considering the decision to execute a go-around when the runway is not visible, flight path clearance is crucial. The aircraft must have a clear path to maneuver safely and effectively, especially if it cannot proceed to land. This involves confirming that there is sufficient vertical and lateral space to climb away from the airport environment without encountering obstacles.

In a go-around scenario, the pilot must also factor in other aircraft in the vicinity, which may be on approach or in the traffic pattern. Ensuring that the approach path is clear of both terrain and other aviation traffic is critical to maintaining safety and avoiding potential collisions.

While fuel levels, wing configuration, and aircraft weight are important factors to assess during flight operations, they do not directly relate to the immediate decisions involving the visibility of the runway and the necessity for a go-around. Thus, the focus should primarily be on ensuring a safe flight path clearance to execute an effective go-around maneuver.
