Preliminary experiments were performed on the NADC Human Centrifuge to determine the effect of steady-state G sub c accelerations on the subjects ability to aim a helmet-mounted sight at stationary targets located at four extreme positions in the subjects field of view. Performance was measured as percent time on target. Average performance decrements ranged were obtained for elevated and eye-level targets. Asymmetrical target performance scores were noted. Coriolis effects were noted also.
