What action should a pilot take if landing gear fails to indicate it is down and locked?

In the scenario where the landing gear fails to indicate it is down and locked, the most prudent action a pilot should take is to conduct a go-around and troubleshoot. This approach allows the pilot to safely regain altitude and reassess the situation without the immediate pressure of landing, which can be particularly critical when uncertain about the landing gear status.

The troubleshooting steps during a go-around might include checking the gear position indicators, attempting to manually extend the gear if applicable, and ensuring that the landing gear selector is in the correct position. This method also allows for communication with air traffic control to inform them of the situation, which can help in securing assistance and planning for a safe landing if issues persist.

By opting for a go-around, the pilot maintains control of the aircraft and can further evaluate the landing gear condition, which is essential for making informed decisions moving forward. This systematic approach helps in reducing the risk of a potential mishap during landing if the gear truly is not in the correct position.

Emergency situations should always prioritize maintaining control of the aircraft and ensuring the safety of all on board, which makes troubleshooting while in a safe configuration a critical aspect of effective flight management.
