Fixed-wing UAVs have a wide size range, with small UAVs having wingspans as small as 15 centimeters and large UAVs having wingspans of several meters. Maximum takeoff weights range widely, from kilograms (such as the 1.9 kg RQ-11 "Raven") to tons (such as the SA750U large unmanned transport aircraft with a maximum takeoff weight of 7.5 tons).
Their cruising speeds typically range from 30 to 240 km/h, with some high-speed models reaching up to 340 km/h. Endurance ranges from 1 hour to over 40 hours, and service ceilings range from 5000 to 8000 meters.
Payloads range from a few kilograms to several tons; for example, the SA750U has a maximum payload capacity of 3.2 tons.
Takeoff and landing methods are flexible and diverse, supporting vertical takeoff and landing (VTOL), catapult launch, and hand-launch . Operating temperatures typically range from -20℃ to +55℃, with some models operating normally in temperatures as low as -40℃. Wind resistance is generally up to level 6 (wind speed 10.8-13.8 m/s) or higher.
The navigation and control system generally supports positioning via multiple satellite navigation systems such as GPS, BDS (BeiDou), and GLONASS, and employs high-precision real-time dynamic (RTK) differential technology to improve positioning accuracy. The flight control system has high attitude control accuracy, with some models exhibiting attitude angle errors ≤1° in static sensor measurements.
