The USAF flying qualities requirements for the Advanced Medium STOL Transport (AMST) are presented. These requirements were intended for a production version of the AMST, and were released as part of the USAF Proposal Instruction Package in 1977. The requirements of the general military specification, 'Flying Qualities of Piloted Airplanes' (MIL-F-8785B) were modified to account for STOL flight characteristics; specific design features of the two AMST prototype airplanes (YC-14 and YC-15); to make the flying qualities requirements compatible with the general military specification for flight control systems (MIL-F-9490D); and to abide by the directives of the AMST System Program Office. The rationale for the modifications are discussed.

A move is underway in the military services to expand the scope of the military flying qualities specification, MIL-F-8785C to include STOL flying qualities. This report is the result of review, analysis and unification of existing STOL flying qualities data in a form facilitating inclusion into the new MIL Standard and Handbook, particularly in the area where STOL aircraft differ from CTOL aircraft. The report recommends proposed requirements where sufficient data exist; the report presents discussion where data are sparse or non-existant. (Author).
