Avionics is used to designate the entire complex of electronic equipment that is installed on board aircraft. Very often in parallel with the word "avionics" is used the abbreviation BREO, which stands for on-board radio electronic equipment. The basic elements of electronic equipment are navigation, communication and control systems.
On-board equipment is a set of devices, systems and units that provide:
• control of the aircraft, including control of the angular position and its trajectory in the solution of transport and combat tasks;
• energy supply;
• providing for the life of the crew and passengers.
Equipment designed to control various devices, as well as providing communication with air traffic management systems and monitoring air and ground conditions, is called avionics or avionics. Equipment that provides power supply (hydraulic systems, power supply systems), vital functions (air conditioning systems), as well as the management of the release and cleaning of the chassis, braking during landing and interrupted start is called air-to-air equipment.
Despite the variety of types, all aircraft have the same basic aggregates that perform similar functions. These units include: a wing, a fuselage, horizontal and vertical tail, a chassis and a propulsion system.
