Some aspects of Human Factors have long been a neglected area in rotorcraft design. This is true of such areas not directly influenced by motion and workload studies: the areas of human factors missing from the domain of human factors are those not included in the engineering set, but in the psychological and physiological set.
Rotorcraft human factors issues are many of the same developed or determined for the aircraft/airplane category and can be divided into groups such as the man, machine, environment. Included are the issues of operating criteria (environment) of the rotorcraft and its pilots, design criteria to aid that pilot to alleviate stress and enable a functional cockpit (machine), and the issues of how best to train the pilot (man), mentally and physically, to accomplish the tasks set before him.
Systems such as aircraft design and operation, crew physiology and training and airspace management need to be revamped and updated.
Solutions must be developed and implemented to better design, man, train and utilize rotorcraft in the future. This will take a coordinated effort by the regulatory agencies and the industry.
