Through this page we will explain to you various different avionics and onboard systems that are common among aircraft of all types.
Airplanes - and aircraft in general terms - are complex systems that are constructed on the basis of the integration of many other subsystems that are not exactly simple, either seen from the perspective of the designer or the manufacturer. However, great care is taken by these manufacturers as well as certification bodies and authorities to create systems and instruments that are easy to interpret and work reliably, thus reducing the risk of system malfunction as well as the incidence of human factors capable of provoking concatenated problems.
Thorough the links contained here you will find various articles, comments and pictures that describe and depict the most important aeronautical systems.
