摘要

The initial M43 aviation protective mask was fielded without provisions foroptical corrective devices. Contact lenses, an interim solution, were not entirely acceptable since a small segment of the population could not be fitted adequately with contacts. This study evaluated visual performance effects and user acceptance of the M43A1 mask with frontsert correction modifications. The subjects were 30 U.S. Army aviators (28 men and 2 women) . Objective data from flight simulation evaluations suggested there were no significant differences between flight performance with and without the mask, despite refractive status. Subjective data from static and flight evaluations reflected positive user acceptance of the new mask and frontserts. Problems may exist in smaller cockpits (OH-58A/C, D), but evidence suggested that this may have been an artifact resulting from testing the mask while wearing protective body armor. Within the range of flight conditions and profiles examined, the M43A1 frontsert system meets U.S. Army aviation needs for optical correction when mission requirements dictate flying with chemical-biological protective masks.
