Abstract. The problem of ensuring helicopter flight safety in conditions of real operation and connection of this problem with functioning of airborne ergative complex elements is considered. The technique for constructing informative functions of danger of current helicopter flight mode because of malfunctioning of BEC elements under the influence of unfavorable factors is revealed as well as connection with the dynamics of movement and the possibility of using in the channels of warning and information support to the crew of the information and control system for helicopter flight safety. The proposed partial and integrated informative hazard functions, their derivatives over time and the gradient of the change according to the helicopter characteristic flight parameters, are shown to reflect the dynamics of the helicopter's movement and associated changes in the safety level of the flight regime, and therefore allow solving the problems of detection and identification of special situations, warning the crew, and constructing steering algorithms for the helm control in the channels of the information and control system of flight safety.  
Keywords: onboard ergatic complex, unfavorable factors, informative function of danger, connection with the dynamics of movement, ensuring flight safety, information-control system
