What are the MIL-F-8785 handling qualities requirements?

MIL-F-8785 (and civilian equivalent FAR 25.143-177) specifies handling qualities requirements in three levels: Level 1 (satisfactory), Level 2 (acceptable), and Level 3 (controllable). Requirements cover: Short period frequency and damping, Dutch roll frequency and damping, Roll mode time constant, Spiral stability time to double, Pitch rate response to stick input, Stick force per g, Control harmony, Minimum control speeds, and Stall characteristics. Requirements vary with flight phase (A: combat, B: cruise, C: takeoff/landing). Cooper-Harper ratings from pilot evaluations validate compliance. Modern specifications include MIL-STD-1797 with more detailed criteria.
