Proposed Incorporation of Mission-Oriented Flying Qualities into MIL-STD-1797A

The effort documented in this report was undertaken to revise the flying qualities military standard, MIL-STD-1797A, in both form and content. It was felt that mission-oriented requirements on new systems would expand the applicability of the standard to all tasks performed in an operational environment. This allows replacement of Flight Phases and reference to aircraft weight with a series of Mission- Task-Elements. Demonstration maneuvers are included to be an independent assessment of handling qualities. Additionally, much of the work done in the definition of flying quality criteria in the twelve years since the MIL-STD was originally proposed has been incorporated. These modifications deal generally with task amplitude, system response type, and control feel system characteristics. Two other important changes are the guidance provided on use of alternative requirements and the linking of flying qualities Levels and the Cooper-Harper Handling Qualities Rating Scale. The results of this effort are expected to be a cornerstone in the process to create MIL-STD-1797B and will be subject to critical review by the aerospace industry as well as a Tri-Service Review Team.
