New Methods for Air Traffic Controller Main Solution Taking Dominant Determination Concerning Their Attitude to Risk

Taking into account the influence of human factor on flight safety one may say that ICAO flight safety main concept components mutually influence each other. This is based on the perspective of “aviation personnel attitude to safe actions and conditions” as the main factor of flight safety. This attitude may be found with help estimate usefulness functions construction and analysis for aircraft flight norms values based on air traffic controllers indexes in decision taking tasks. One way to find the main solution is taking dominant that defines air traffic controller attitude to flight level norms violation as to risk (tending, indifferent, non-tending to risk) is with the help of a “risk premium” criterion. Historically, the criterion included a single variable point in estimate usefulness function. Two improved criteria that include several characteristic points of usefulness function are proposed. As a result of new criteria appliance the main solution taking dominant determination efficiency increased up to 18 %.
