The report proposes a simple approach to automatic control for flying zero-G and subgravity maneuvers in a JC-131 aircraft. The method outlined involves modifying the aircrafts autopilot to sense and control pitch acceleration instead of pitch displacement. A parabolic display-control unit, designed to provide a visual display for zero-G flying, is used to develop an acceleration error signal to control the aircraft through a modified autopilot. Instrumentation and changes necessary to adapt the E-4 autopilot for zero-G and subgravity flying are discussed. Also discussed is a solution to the problem of extending the time a capsule may be kept in a zero-G free-floating state through use of a modified type B-7 flight controller and a third pilot controlling the aircraft from the float compartment.
