1.1 This specification will cover the flight characteristics of fixed-wing aircraft with a certified maximum take-off weight of 8618 kg [19 000 lb] or less and a passenger-seating configuration of up to 19 at low speed and provide standards for departure characteristics, spinning, and stall warning.

1.2 The term “aeroplane” is utilized in this specification as it was originally conceived for normal category fixed wing aircraft with a maximum certificated weight of 8618 kg [19 000 lb] or less and a passenger seating configuration up to 19 as defined in the Rules. However, these standards may be more broadly applicable and their usage should not be unnecessarily limited.

1.3 The applicant for a design approval shall seek the individual guidance to their respective civil aviation authority (CAA) body concerning the use of this specification as part of a certification plan. For information on which CAA regulatory bodies have accepted this specification (in whole or in part) as a means of compliance to their Airworthiness Rules (hereinafter referred to as “the Rules”), refer to ASTM Committee F44 webpage (www.astm.org/COMMITTEE/F44.htm), which includes CAA website links.

1.4 It is the responsibility of the applicant to validate any applicability beyond that identified in this specification and request acceptance from the applicable CAA.

1.5 Units—Normally, the values stated are SI units followed by U.S. Customary Units in square brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. In some cases other units may be used exclusively (such as knots) and no other unit will be identified. This technique should be used sparingly and rationale for its use shall be clear and included in the standard.

1.6 This 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.

1.7 This 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.
