What is the maximum KIAS allowed to raise and lower the landing gear?

The correct choice of 135 KIAS for the maximum indicated airspeed (KIAS) allowed to raise and lower the landing gear is based on safety and operational guidelines established for the MQ-9 aircraft. This speed limit is set to ensure that the landing gear system, which includes the gear itself and the associated mechanisms, operates effectively without risking structural damage or malfunction during the critical phases of gear operation.

Exceeding this maximum airspeed while raising or lowering the landing gear could introduce excessive aerodynamic forces on the gear components, potentially leading to failure or compromised operation. This is a vital safety consideration, as the landing gear is crucial for a successful landing and must deploy correctly under controlled conditions. Adhering to this limitation helps maintain the integrity of the aircraft's systems and enhances overall safety during flight operations.
