![]() There are various forms of testing, and many aircraft manufacturers will pre-define how to test. All avionics systems today are required to pass certain levels of environmental testing. Some systems need to be more robust than others. Large aircraft projects like military and civilian often require hundreds of engineers to integrate these complex systems.ĭifferent flight environments have different system uses. No matter how small an aircraft is, some level of integration is essential such as power supply. The unprecedented complexity of software is being used to meet ever more demanding aviation standards. What started as a simple problem of how to communicate switching variables on discrete data lines has now evolved into a complex problem of how to coordinate flight control data transmitted on optical data buses. Since the earliest days of the avionics industry, how to connect its numerous electronic systems and use various information closely and effectively has been a headache. However, any system on the aircraft has a certain degree of robustness requirements. ![]() A necessary factor in building an avionics system is the requirement that the flight control system cannot fail at any time. As aircraft and crews rely more and more on avionics systems, the robustness of these systems becomes important. There are many expensive, time-consuming, troublesome, and difficult aspects of manufacturing any aircraft, and airworthiness certification are one of them. The electronic environment faced by aircraft is unique and sometimes highly complex. Design Constraints Related to Avionics:Īny device on an aircraft must meet a series of demanding design constraints. At the same time, civil aircraft naturally require all avionics systems to be confined in the cockpit, thus making civilian aircraft affect the military field for the first time in terms of budget and development. As more and more people use airplanes as their primary means of transportation, people continue to develop more sophisticated control technologies to ensure the safety of airplanes in limited airspace. The flight control system (fly-by-wire flight control) and the new navigation requirements brought about by harsh airspace conditions have also led to a corresponding increase in development costs. Many aircraft have become flying sensor platforms, and how to make sensors work together has become a new problem.Īvionics is experiencing tremendous growth in the civilian market. The main impetus to promote the development of avionics technology comes from the military needs during the Cold War rather than the civilian field. With the integration of the electronics industry, the avionics market has flourished. ![]() Military aircraft are increasingly becoming a combat platform integrating a variety of powerful and sensitive sensors.Īvionics was born in the 1970s. Many aircraft today exist solely to carry these devices. At first, avionics was just an accessory system of an aircraft. There are many types of avionics equipment for different purposes, ranging from the simplest searchlights on police helicopters to complex airborne early warning platforms.Īvionics research is changing aerospace technology at an astonishing rate. ![]() A basic avionics system consists of multiple systems such as communication, navigation, and display management. Avionics refers to the sum of all electronic systems on an aircraft. ![]()
