Aviation and electronics join to form the word avionics – basically it is equipment that is installed in aircraft or spacecraft to conduct hundreds of mission and flight management tasks, such as navigational systems, engine controls, flight control systems, communications, weather radar, lighting systems, threat detection, fuel systems, and performance monitors.
Various types of electronic systems are employed in modern aircraft, spacecraft, and artificial satellites in order to accomplish their purpose and mission. As a general rule, the more complex the craft or mission, the more complex the electronic systems employed.
Commercial airliners, helicopters, military fighter jets, unmanned aerial vehicles (UAVs), business jets, and spacecraft all rely on avionics to perform functions, complete missions, conduct research, monitor performance, and ensure safety requirements are met. As well as improved performance and maintenance, advanced avionics systems integrate multiple functions.
