1、Designation:F2317/F2317M10Standard Specification forDesign of Weight-Shift-Control Aircraft1This standard is issued under the fixed designation F2317/F2317M;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 covers the minimum airworthinessstandards a manufacturer shall meet in the designing,testing,and labeling of weight-shi

4、tors.Flexible sail surfaces typically found on weight-shift aircraft are notconsidered hinged surfaces for the purposes of this specification.1.3 Weight-shift-control aircraft means a powered aircraftwith a framed pivoting wing and a fuselage(trike carriage)controllable only in pitch and roll by the
5、 pilots ability tochange the aircrafts center of gravity with respect to the wing.Flight control of the aircraft depends on the wings ability toflexibly deform rather than the use of control surfaces.1.4 This specification is organized and numbered in accor-dance with the bylaws established for Comm
