In what aspect does the MQ-9 primarily differ from traditional manned aircraft?

The MQ-9 primarily differs from traditional manned aircraft in its method of operations, which is remotely piloted. Unlike conventional aircraft that require a human pilot to be onboard and actively control the aircraft, the MQ-9 operates through the use of advanced remote piloting technology. This allows for operations from a significant distance, often thousands of miles away from the actual aircraft.

This remote operation not only enhances the safety of the personnel involved—since they are not placed in harm's way—but also enables the MQ-9 to conduct missions that might be too dangerous for manned aircraft. Additionally, the ability to operate without a human pilot allows for longer flight durations and greater operational flexibility in various mission profiles.

In contrast, while speed, altitude capabilities, size, and weight can also differ between the MQ-9 and manned aircraft, these aspects are characteristic features of different types of aircraft rather than the defining operational method that sets the MQ-9 apart from traditional manned aircraft.
