A fixed base manned V/STOL handling qualities simulation was performed to investigate 1) classification criteria of attitude and rate command systems in hover and low-speed flight; 2) control system blending schemes for transition from approach dynamics to hover dynamics and vice versa, and 3) the amount of control usage. Pilot ratings and comments showed that a time response criterion discriminated well between attitude and rate systems; blending schemes for transition correlated well with earlier NASA results and; pilot's command gain had a strong effect on piloting characteristics and the amount of control usage.

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).

A rationale for quantifying fixed wing V/STOL aircraft field of view requirements is developed and illustrated by a variety of examples involving shipboard recovery. The analytic technique employed involves the dynamic modeling of (a) the recovery guidance and control situation, (b) the disturbance environment, (c) the augmented aircraft, (d) the pilot's multiloop control activities, (e) the perceptual behavior of the pilot as affected by the limitations associated with visibility and divided attention, and (f) the resulting geometric properties of informative elements within the visual field. The foregoing factors are combined to enable the analyst to indentify those areas of the field of view which are essential for perception of the cues necessary for guiding and controlling the powered-lift aircraft to a safe recovery. The analytic technique accounts for the combined variability in field of view caused by rolling, pitching, yawing, surging, swaying and heaving degrees of freedom of the aircraft as the pilot attempts to guide and control the aircraft over the recovery area on the moving ship.

The report uses as a point of departure the concept that control of bank angle is the primary piloting task in maintaining or changing heading. Regulation of the bank angle to maintain heading is a close-loop tracking task in which the pilot applies aileron control as a function of observed bank angle error. For large heading changes, the steady-state bank angle consistent with available or desired load factor is attained in an open-loop fashion; it is then regulated in a closed-loop fashion throughout the remainder of the turn. For the transient entry and exit from the turn, the pilot is not concerned with bank angle per se, but rather with attaining a mentally commanded bank angle with tolerable accuracy in a reasonable time, and with an easily learned and comfortable program of aileron movements.
