[Quantitative ranges and methods of evaluation of occupational reliability of aviation specialists].

The authors present concept of occupational reliability of an operating human. The concept is based on systemic approach to analysis of erroneous acts as results of stochasticity of inner human traits and outer interferences. The authors justify universal, systemic criterion to analyze reliability of occupational activities (potential unreliability of acts). The criterion helped to solve practical problems of quantitative evaluation and forecast of outer influence on occupational reliability of a pilot. The criterion is adequate for analysis of "risk-profit" correlation to optimize material expenses among the components of "human-machine" system being under elaboration, preparation and in use.

[Establishing the personal identity of the victims in aviation catastrophes].

Algorithm of organization measures and expert investigations is proposed, based on experience gained in expert studies during liquidation of aircraft catastrophes. It permits effective classification, differentiation, and identification of victims and is based on traditional and high technological methods of investigation.

Samuel Franklin Cody: aviation and aeromedical evacuation pioneer.

In the summer of 1913, Woodrow Wilson had just become the 28th President of the United States and King George V was on the throne of the United Kingdom. It was nearly 10 yr since the historical flight at Kitty Hawk and 3 yr since Blériot had first flown the English Channel. At Farnborough, "Colonel" Samuel F. Cody, originally a horseman, hunter, crack shot, showman and theatrical impresario from the USA, was preparing a new floatplane for a round Britain flying race. One of the features of the floatplane, a biplane with a four bladed pusher propeller, was that it had already demonstrated its ability to carry passengers. Cody calculated that it would allow him to carry five passengers for a 4-h flight and may even have medical uses. He arranged a demonstration of its potential as an air ambulance at Farnborough. This paper describes, with the use of photographs of the event, the airplane, the demonstration and the reasons why it would be left to others to carry out the first, real aeromedical evacuation 4 yr later.

Further support for the concept of a G-LOC syndrome: a survey of military high-performance aviators.

METHODS: Some 329 military high-performance pilots were anonymously surveyed to determine the occurrence rates for a symptom complex of acceleration-induced neurologic manifestations. The premise for this symptom complex is the theory that acceleration-induced neurologic effects are not always an all-or-none phenomenon with G-LOC as the operational endpoint. RESULTS: A significant number of aircrew in selected types of aircraft reported symptoms such as euphoria, apathy, displacement, depersonalization, poor response to auditory stimuli, immediate memory difficulties, sensory abnormalities, motor abnormalities, confusion, and dream-like state without loss of consciousness. CONCLUSION: These findings may signal a need for alterations in G-awareness training.

Sudden incapacitation encountered in flight by professional pilots in French civil aviation, 1948-1972.

This report concerns 17 incidents of sudden incapacitation of professional airline pilots in flight in the period 1948-1972. The high incidence of cardio-vascular accidents is noteworthy: 13 cases of which 11 were due to coronary infarction. There were two cases of unperdictable epileptic fits. None of the above gave rise to an accident. For an accident to occur, several conditions must be fulfilled at the same time: 1) The incapacity must affect the pilot at the controls; (2) The incapacity must be sudden; (3) The incapacity must take place during a critical phase of take-off or final apprach.

The evolving role of corporate medical departments in commercial aviation.

Dr. McKenas, who is Corporate Medical Director at American Airlines, describes some of AA s innovations in addressing on-board medical emergencies. These programs include Physician-on-Call and installation of automatic external defibrillators. The value of internal OM departments in matching medical services to changing traveler demographics, and in accident response such as was required on September 11, 2001, are also briefly discussed.
