The book discusses the basic principles of the implementation of electronic equipment (RES) and design options for RES for various purposes. General design issues are outlined, including organization and methodology, specifics of ensuring manufacturability of structures, internal electromagnetic compatibility; methods of protection against heat, moisture, mechanical effects, issues of external design of RES, taking into account the requirements of ergonomics and technical aesthetics. The specificity of avionics equipment of the ultra-high frequency range, ground, on-board, radioelectronic and electronic computing avionics equipment is presented.
