Использование виртуальной глиссады для вычисления отклонений летательного аппарата на конечном участке посадки

Abstract

Objective: The development of a calculation method of aircraft guidance parameters (linear and angular deflection from a synthetic glide path) by means of global satellite navigation system signals. As opposed to the existing methods, it is suggested to use an inclined plane, containing a glide slope line, as a base surface for vertical guidance. Methods: An experimental research was carried out, based on the suggested method of deflections’ calculation, as well as the comparison of results was fulfilled with identification of guidance parameters’ data by means of the existing methods. Results: It is shown that the results of calculating deflections from a glide path by means of the developed method and those methods, which are currently applied in transport planes landing, are practically the same. Practical importance: Application of the given method of calculating aircraft deflections from a glide path will make it possible to simplify significantly the deployment of the ground segment of landing system in airports, which in its turn will give the opportunity to equip regional airdromes of the third and the forth class, which are currently equipped with imprecise approach systems (compass locators or, the so-called, VOR) or have no radio-navigation aids, with satellite systems of precision approach. Satellite landing system implementation will allow aircraft crews, provided with proper airborne equipment, to pass, in case of need, from a contact fly to an instrumental fly conducted under flight rules. The above mentioned will reduce airdromes meteorological minimum, which in its turn will cause the decrease in the number of non-flying days and increase the efficiency of airdromes and fleet exploitation. One more advantage of satellite landing system application is the fact that it allows students to work out the procedure of approach on instrument landing system.
