1、Designation: F3173/F3173M 17Standard Specification forAircraft Handling Characteristics1This standard is issued under the fixed designation F3173/F3173M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A

2、number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification addresses the airworthiness require-ments for aeroplane handling characteristics in flight and onground and water.1.

3、2 The term “aeroplane” is utilized in this specification asit was originally conceived for normal category fixed wingaircraft with a certified maximum take-off weight of 19 000 lbor less and a passenger seating configuration up to 19 asdefined in the Rules. However, this standard may be morebroadly

4、applicable.1.3 The applicant for a design approval must seek individualguidance from their respective CAA body concerning the useof this specification as part of a certification plan. For infor-mation on which CAA regulatory bodies have accepted thisspecification (in whole or in part) as a means of

5、compliance totheir Airworthiness Rules (hereinafter referred to as “theRules”), refer to the ASTM Committee F44 webpage(www.ASTM.org/COMITTEE/F44.htm) which includes CAAwebsite links. It will be the responsibility of the applicant tovalidate any applicability beyond that identified in this speci-fic

6、ation and request acceptance from the applicable CAA.1.4 UnitsNormally, the values stated are SI units followedby US customary units in square brackets. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from

7、the two systems may result in nonconformancewith the standard.1.5 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
