Abstract

It is known that the main goal of passenger and cargo airlines is the most stable profitability with a positive gradient of its growth. This goal is provided by a number of factors, among which the prime cost of operating aircraft (AC) on the routes of passenger and cargo transportation lines plays an important role. Based on the analysis of the world and domestic air transportation market, the article highlights the main factors that determine the level of the cost of flights. The analysis of these factors showed that the cost of flights is a complex multifactorial problem that is solved by air carrier companies sequentially at a number of stages as a large amount of information accumulates.At the same time, an air carrier needs a very approximate, but prompt method of assessing this cost, especially at the stage of its entry into the air transportation business.A detailed analysis of the dependence of the cost of air transportation on the length of the runway, proposed by the General Designer O.K. Antonov for an express assessment of this complex parameter in relation to cargo aircraft, which we have expanded for the type of passenger aircraft. The analysis showed the admissibility of considering the curve Scost=f(LRS) as a function of the mathematical expectation of the cost of air transportation, and the points lying outside this curve as the variance of the cost, i.e. as the risk of choosing an alternative aircraft option.The main factors that predetermine the level of the cost of air transportation have been synthesized, among which the factor of non-stop flight is of particular importance, i.e. range. This made it possible to develop the idea of O.K. Antonov to present as an approximate criterion of efficiency the dependence of the cost of air transportation on the range of the aircraft in the form of a hyperbolic dependence of a similar type.The analysis of the efficiency of the proposed method for assessing the effectiveness of the criterion of the cost of air transportation from the flight range of the aircraft showed the validity of its application for the express assessment of the preliminary choice by the aircraft operator at the initial stage of his development of the air transportation business.
