ABSTRACT
Military aviators, test pilots, and some airline pilots know the problems associated with flight at high altitudes. These physiological problems are less well known to civilian pilots due to lack of training. The study of human factors strives to find the causes for human behavior in a general sense and attempts to apply the lessons learned in a real-time sense. Human beings bring to aviation a variety of traits, beliefs, and attitudes that bear heavily upon their performance. Human error, or as it was formerly called, "pilot error" is far and away the most common cause of aircraft accidents. The human body limits the design of the cockpit. Whether a control or a switch is comfortable and reachable affects the pilot's performance. Changing the pilot by training to suit the equipment is not the answer. The two disciplines, Human or Psychological Factors and Physiological Factors have been, with some exceptions, considered individually for a long time productive way.
