China Civil UAV Theory Questions — Questions 1–10

UAVs by range (lower bound exclusive, upper bound inclusive): ultra-short-range — within 15 km; short-range — 15–50 km (including 50 km); short-haul — 50–200 km (including 200 km); medium-range — 200–800 km (including 800 km); long-range — over 800 km.

Light UAV: empty weight over 7 kg and up to 116 kg, with a calibrated airspeed below 100 km/h (55 kt) in full-power level flight and a ceiling below 3,000 m. Small UAV: empty weight of 5,700 kg or less, excluding micro and light UAVs. Large UAV: empty weight over 5,700 kg. Study note: (1) the lower bound of each weight class is exclusive — greater than, not including equal; (2) every tested definition uses empty weight — any option that just says "weight" is wrong.

Per the UAV classification method in the Regulations on the Management of Civil UAV Pilots. Study note — key figures to remember: Class I is keyed to 1.5 kg; Class II to VLOS operation; Classes III and IV to the figure 5; Class V to plant-protection aircraft and Class VI to airships (neither has a weight limit); Class VII to BVLOS Classes I and II; Class XI to two 5,700 kg figures and Class XII to one 5,700 kg figure.

Judging from the description, this question tests the 2015 or 2018 UAV classification standard. The Class III standard is the same in both versions: 4 kg < empty weight ≤ 15 kg, 7 kg < takeoff weight ≤ 25 kg.

UAVs by range (lower bound exclusive, upper bound inclusive): ultra-short-range — within 15 km; short-range — 15–50 km (including 50 km); short-haul — 50–200 km (including 200 km); medium-range — 200–800 km (including 800 km); long-range — over 800 km.

A multirotor aircraft falls under the rotorcraft category. A rotorcraft is an aircraft that generates lift from one or more rotors. A multirotor aircraft achieves flight through the coordinated control of multiple rotors, so it is classified as a rotorcraft.

UAVs by flight altitude (lower bound exclusive, upper bound inclusive): ultra-low-altitude UAV — altitude ≤ 100 m; low-altitude UAV — 100 m < altitude ≤ 1000 m; medium-altitude UAV — 1000 m < altitude ≤ 7000 m; high-altitude UAV — 7000 m < altitude ≤ 18000 m; ultra-high-altitude UAV — altitude > 18000 m.

Scope of the Regulations on Real-Name Registration Management of Civil Unmanned Aircraft: these regulations apply to civil UAVs within China with a maximum takeoff weight of 250 g or more (including 250 g).
