The method for determining the main parameters of the tail cargo doors of transport category aircrafts is developed. A methodology for the ascertainment of these parameters has been described. An example based on an existing transport aircraft is considered. Gathered were information pertaining to the necessary design, operational and regulatory parameters and requirements of the international regulatory organisations Federal Aviation regulations (FAR), Certification Specification (CS) and Aviation Regulations (AR). The principle of determining the dimensions of the cargo compartment, cargo floor and the hitting platforms, in the form of a ramp with a pressure door and ladders, is presented based on the initial data. Considering the described loading and unloading, as well as landing, operations, the dependence of the ramp length on the length of the cargo floor is ascertained. A method for designing a cargo door fairings in the transport category aircraft fuselage tail part is presented. The main features of the fairings compartment have been determined, together with those of its main components and their varieties, depending on the scheme of the cargo door. Information is provided on the fairings compartment structural elements parameters selection.
