ASTM F 3793 : 2026

1.1This specification covers minimum flight characteristics and performance requirements for aircraft, and is applicable to aircraft capable of any wing-borne flight, semi-thrust-borne flight, and thrust-borne flight, or combinations thereof. Specifically, this version of the specification is focused on airplanes, helicopters, and powered lift types. Many of the requirements specified likely apply to other aircraft types as well, but the applicability to other types must be assessed on a case-by-case basis.

1.2This specification also covers required testing needed to establish the operating limitations and performance values that will be listed in the Pilot’s Operating Handbook (POH).

1.3Units—The values given in this standard are in SI units and are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound (or other) units that are provided for information only and are not considered standard. The values stated in each system may not be exact equivalents. Where it may not be clear, some equations provide the units of the result directly following the equation.

1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
