Designation: F3793 − 26aStandard Specif i cation forFlight Characteristics and Performance 1This standard is issued under the f i xed designation F3793; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (´) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specif i cation covers minimum f l ight characteristicsand performance requirements for aircraft, and is applicable toaircraft capable of any wing-borne f l ight, semi-thrustbornef l ight, and thrustborne f l ight, or combinations thereof.Specif i cally, this version of the specif i cation is focused onairplanes, helicopters, and powered lift types. Many of therequirements specif i ed likely apply to other aircraft types aswell, but the applicability to other types must be assessed on acase-by-case basis.N OTE 1—The subcommittee is actively developing this specif i cation sothat future versions apply to a wider range of aircraft types andcapabilities.1.2 This specif i cation also covers required testing needed toestablish the operating limitations and performance values thatwill be listed in the Pilot’s Operating Handbook (POH).1.3 Units—The values given in this standard are in SI unitsand are to be regarded as standard. The values given inparentheses are mathematical conversions to inch-pound (orother) units that are provided for information only and are notconsidered standard. The values stated in each system may notbe exact equivalents. Where it may not be clear, someequations provide the units of the result directly following theequation.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.2.

Terminology3.1 Def i nitions:3.1.1 aircraft conf i guration, n—particular combination off i xed components, moveable elements, and removable itemsthat affect the aerodynamic or operational characteristics of theaircraft.3.1.1.1 Discussion—Fixed components include items suchas wing(s), fuselage, empennage, propulsion system, andlanding gear. Moveable elements include items such as wingf l aps, cowl f l aps, rotor tilt, landing gear, equipment, andsoftware conf i guration. Removable items include items such asinternal or external components, ballast, camera mounts, en-ergy storage devices, and so forth.3.1.2 envelope awareness system, n—a system that alerts thepilot that the aircraft is near or exceeding envelope limits butdoes not prevent pilots from exceeding those limits.1 This specif i cation is under the jurisdiction of ASTM Committee F37 on LightSportAircraft and is the direct responsibility of Subcommittee F37.02 on FunctionalContent.Current edition approved May 15, 2026.
