HB 8736-2023 General requirements for civil vertical take-off and landing fixed-wing unmanned aircraft system
1 Scope
This document specifies construction, classification, functions, performance and test for verification requirements for civil vertical take-off and landing (VTOL) fixed-wing unmanned aircraft systems (UAS).
This document applies to civil vertical take-off and landing fixed-wing unmanned aircraft systems (hereinafter referred to as “VTOL UASs”) with a maximum take-off weight not greater than 150kg, and may apply to other types of UASs as a reference.

3 Terms and definitions
For the purposes of this standard, the terms and definitions given in GB/T 38152 and the following apply.
3.1
vertical take-off and landing (VTOL) fixed-wing unmanned aircraft
fixed-wing unmanned aircraft that relies on its own power plant to take off and land vertically
3.2
mission payload weight
sum of the weight of the airborne equipment required to accomplish a specific mission, and the weight of the energy sources, auxiliary devices, additional mounted structures, etc., required for its proper functioning
3.3
power source weight
weight of the fuel or power cell required for power output
3.4
mission take-off weight
sum of the weight of the empty aircraft, the mission payload weight and the power source weight
Note: It is classified into the maximum take-off weight and normal take-off weight by load.
3.5
fixed-wing mode
process of controlling the attitude, speed and position of a VTOL UAS which is fulfilled mainly relying on the flight control surfaces and horizontal flight propulsion of the unmanned aircraft
3.6
transition mode
process of switching between the VTOL mode and the fixed-wing mode
3.7
vertical take-off and landing (VTOL) mode
process of controlling the attitude, horizontal position and altitude of a VTOL UAS which is fulfilled mainly relying on the forces and moments generated by the VTOL propulsion
