ACTUALIZATION OF METHODIC OF CALCULATION OF ACTUAL INDICATOR OF CIVIL AIRCRAFT DISPATCH RELIABILITY

Abstract

Dispatch reliability – is one of the key criteria of aircraft technical operation process efficiency which reflects economic efficiency of airline activity. The higher the operational reliability, the better the level of aircraft operation in airline, the higher maintenance quality and safety policy is more effective. Due to the lack of unified procedure of dispatch reliability control both for aircraft manufacturers and Russian Federation aircraft operators and based on international experience it was concluded that there is a need for dispatch reliability specification by introducing a number of parameters, definitions and development, thereby the unified updated methodic of calculation. In this work six basic and three auxiliary parameters are introduced, the following terms and definitions are established: dispatch reliability, operational reliability, ground operational interruptions, operational interruptions, in-flight interruptions. A unified actualized methodic of dispatch reliability and operational reliability calculation is developed, which is reasonable and more accurate. Since the aircraft dispatch reliability includes the notion of Regularity and Punctuality, definitions and criteria calculation are given. The detailed example of criteria calculation is shown: dispatch reliability, dispatch regularity, flight punctuality, operational reliability, flight delays for a hundred landings, aircraft changes for a hundred landings, flight cancellations for a hundred landings.
