Aeromedical Training For Flight Personnel

1 FM (1-301)DISTRIBUTION RESTRICTION: Approved for public release; distribution , DEPARTMENT OF THE ARMYM anual Provided by eMilitary Manuals - learned from previous military conflicts and recent contingency operations havecaused changes in Army aviation doctrine and the development of more sophisticated aircraftand weapons systems. Army aircrew members must be capable of operating these systemsaround the clock, in austere environments, and under adverse conditions. They must becapable of employing these systems and avoid enemy air defense and air-to-air weaponssystems.

2 The hazards of stress and fatigue imposed by operating more sophisticated systems incombat operations and CONOPS will eventually take a toll in aircrew performance and couldjeopardize mission accomplishment. Aircrew members must be trained to recognize andunderstand these hazards. Training can prepare aircrew members and prevent stress andfatigue from reducing their mission effectiveness and increase their chances of manual gives aircrew members an understanding of their physiological responses to theaviation environment; it also describes the effects of the Flight environment on individualmission accomplishment.

3 In addition, it outlines the essential Aeromedical trainingrequirements (in Chapter 1) that assist the commander and Flight surgeon in conductingaeromedical education for Army aircrew members. The subject areas addressed in the trainingare by no means all inclusive but are presented to assist aircrew members in increasing theirperformance and efficiency through knowing human limitations. This manual is intended foruse by all Army aircrew members in meeting requirements set forth in AR 95-1, TC 1-210,and other appropriate aircrew Training proponent of this publication is Headquarters, TRADOC.
