7、1 manufacturer, nentity responsible for assembly andintegration of components and subsystems to create a safeoperating sUAS. The builder of kit built systems provided bya manufacturer must conform to the manufacturers assemblyand test instructions without deviation in order for that kit-builtsystem

8、to meet this standard.3.1.2 propulsion system, nconsists of one or more powerplants (for example, a combustion engine or an electric motorand, if used, a propeller or rotor) together with the associatedinstallation of fuel system, control and electrical power supply(for example, batteries, electroni

9、c speed controls, fuel cells, orother energy supply).3.1.3 small unmanned aircraft system, sUAS, ncomposedof the small unmanned aircraft (sUA) and all required on-boardsubsystems, payload, control station, other required off-boardsubsystems, any required launch and recovery equipment, andcommand and

10、 control (C2) links between the UA and thecontrol station. For purposes of this standard sUAS is synony-mous with a small Remotely Piloted Aircraft System (sRPAS)and sUAis synonymous with a small Remotely PilotedAircraft(sRPA).3.1.4 supplier, nany entity engaged in the design andproduction of compon

11、ents (other than a payload which is notrequired for safe operation of the sUAS) used on a sUAS.3.1.4.1 DiscussionWhere the supplier is not themanufacturer, the supplier can only ensure that the componentscomply with accepted consensus standards.3.2 Shall versus Should versus MayUse of the word“shall

12、” implies that a procedure or statement is mandatory andmust be followed to comply with this standard, “should”implies recommended, and “may” implies optional at thediscretion of the supplier, manufacturer, or operator. Since“shall” statements are requirements, they include sufficientdetail needed t

13、o define compliance (for example, thresholdvalues, test methods, oversight, reference to other standards).“Should” statements are provided as guidance towards theoverall goal of improving safety, and could include onlysubjective statements. “Should” statements also represent pa-rameters that could b

14、e used in safety evaluations, and couldlead to development of future requirements. “May” statements1This test method is under the jurisdiction of ASTM Committee F38 onUnmannedAircraft Systems and is the direct responsibility of Subcommittee F38.01on Airworthiness.Current edition approved Jan. 15, 20
