What should a pilot do when uncertain about a landing?

When a pilot is uncertain about a landing, the best course of action is to perform a go-around for another attempt. This decision is based on safety considerations. A go-around allows the pilot to reassess the situation, maintaining control of the aircraft and ensuring that they have optimal conditions for a safe landing.

Attempting to land when uncertain can lead to risky situations, particularly if visibility is poor, the approach is unstable, or if there is an issue with the aircraft's configuration. A go-around provides the pilot with the opportunity to rectify these issues rather than committing to a landing that may not be safe.

While contacting air traffic control can be helpful in uncertain situations, it does not directly address the immediate need for the pilot to ensure their approach and landing conditions are satisfactory. Reducing speed and trying again may not be effective unless the pilot has identified a specific issue that can be corrected, which is often better handled through a go-around.
