What is the maximum gear extension speed for lowering the gear?

The maximum gear extension speed for lowering the gear is specified as 220 KIAS. This speed limit is crucial for ensuring safe and effective deployment of the landing gear. When descending at higher speeds, the aerodynamic forces acting on the gear increase, which could potentially lead to gear malfunction or failure during deployment. By adhering to the maximum gear extension speed, pilots can ensure that the gear extends properly and safely, reducing the risk of damage and ensuring a reliable landing configuration. This limit is set based on aircraft design and performance characteristics, which inform acceptable operational parameters.

Other choices, while often related to operational limits, do not correctly represent the maximum speed for gear extension. 15,000 feet does not pertain to speed but rather to altitude considerations, and the other speed options do not align with the specified safety guidelines for gear deployment. Familiarity with these limits is essential for pilots to maintain aircraft control and ensure safe operations during landing phases.
