Analysis of DME/DME positioning capabilities for borispil airspace region

Abstract

Case of on board equipment failure or in case of unavailability of GNSS support (for example: result of some errors), flight management system (FMS) has to use other alternative methods for positioning. FMS has got diferent positioning alghoritms with is grounted on current navigation aids infrastructure [1]. One of them uses distance measurement equipment (DME) for this purpose. DME positioning technics are the most accurate in this situation and avalible on the bigger part of Ukrainian airspace. In this case, it is possible to regard DME like an alternate source of positioning, navigation and timing during the absence of GNSS service. That’s why, DME actively supported by airlines regional carriers and high-end business operators who are equipped with advanced DME avionics. The main task of distance measuring equipment is to provide pilots with distance information between the aircraft and the ground station and is used in all phases of flight. It`s effective tool for strengthening pilot navigation and increasing situation understanding. This technology gives the able pilots to determine exact locations while en route as well as identify descent points on an instrument approach.
