What is the maximum speed for emergency landing gear extension?

The maximum speed for emergency landing gear extension is specified to ensure that the landing gear can be safely deployed without the risk of structural damage to the aircraft or complications in the gear mechanism. In this case, the maximum speed of 100 KIAS allows pilots to manage the aircraft's speed effectively while ensuring the gear can extend properly. Exceeding this speed during emergency procedures could lead to increased aerodynamic loads on the gear assembly, potentially resulting in malfunction or failure to properly deploy the landing gear.

Each aircraft may have different limitations, and in a multi-engine environment, understanding these speeds is crucial for safe operations, especially when dealing with emergency scenarios. Pilots must always refer to the specific aircraft's operating handbook for the correct parameters relevant to their plane. The other options present higher speeds that would not be consistent with safe gear extension practices, emphasizing the importance of adhering to the maximum speed limit established for emergency situations.
