[Peculiarities of medical backup of low flight course and nap-of-the-earth]

Authors presented peculiarities of low flight course and nap-of-the-earth: quick change of orientation cues, ground proximity, possible bird collision, loss of radio signal, exposure of oscillating acceleration, caused by increased atmosphere turbulence. It is showed that low flight course and nap-of-the-earth require special health status of pilots, who must be ready to evaluate obstacle distance, obstacle position relative to aircraft plane, gain in altitude, flight elevation and closing speed, new obstacles and make a decision to fly-by or turn. These circumstances cause emotional tension that affects working capacity and professional reliance. Air medical officer should take additional measures for medical backup of these flight courses.
