The landing gear warning horn is designed to sound when the gear is not safe. This is important for the pilot to be alerted in case there is an issue with the landing gear, such as it not being fully extended or locked in place. The warning horn helps to ensure the safety of the aircraft during takeoff and landing by providing an audible alert to the pilot, allowing them to take necessary actions to address any landing gear problems before it becomes a safety issue.Rate this question:
