The maximum speed of 160 KIAS applies when the MQ-9 has what condition?

The maximum speed of 160 KIAS (Knots Indicated Airspeed) for the MQ-9 is applicable only when the landing gear is not deployed. This condition indicates that the drone is flying without hindrances that would typically arise from deploying gear, which can create drag and limit the overall speed capability of the aircraft.

In a clean configuration—meaning without deployment of landing gear—the MQ-9 can achieve optimal aerodynamic performance, allowing it to reach this maximum speed efficiently. The other conditions, such as having the landing gear extended, having remote control mode active, or being over the weight limit, could introduce variables that affect the aircraft's speed and performance in various ways, typically reducing its operational efficiency or speed.

Understanding the aerodynamic principles behind how the configuration of the aircraft can impact its flight characteristics is key to effectively operating and controlling the MQ-9.
