What is an indication that the landing gear warning horn should activate?

The activation of the landing gear warning horn serves as a crucial safety feature in aircraft operations, alerting pilots when the landing gear is not in the proper configuration for landing. The specific scenario that triggers this warning is when the power levers are retarded below a certain N1 range while the landing gear is not down and locked.

This situation indicates that the aircraft is in a flight configuration that suggests descent and preparation for landing but lacks the necessary landing gear extension. Retarding the power levers generally signifies that the pilot is reducing thrust, potentially positioning the aircraft for landing. If the landing gear is not extended at this point, the warning horn is activated as a reminder to ensure that the aircraft is safe for landing, thereby preventing a potential crash due to landing without the landing gear properly deployed.

The other scenarios presented do not trigger the landing gear warning system. Extended flaps do not indicate a gear-related issue, as flaps can be used in flight configurations that allow for safe landings irrespective of gear status. Low fuel pressure can be a concern for engine operation but does not affect the landing gear configuration. High N1 readings relate to engine performance and do not impact the position of the landing gear either. Therefore, the correct answer is the condition associated
