Abstract:

High accelerations, especially in the Z-direction, prevail during certain flight phases of airplanes or spacecraft. The resulting G-forces can severely hamper the crews ability to move body segments andor to operate controls as indicated in abundancy by often anecdotal case reports. Grethers overview of the literature, reveals surprisingly little systematic research regarding the capability to exert muscular strength for control operation under high acceleration. This lack of information does not only pertain to the operation of seldomly used or new controls like for ejection initiation during extreme G-conditions, but applies even to such common controls as stick, throttle, or sidearm controller.
