The blue switches take off

The word "avionic" is a combination of aviation and electronics. Avionics therefore refers to all electronic devices and systems used in aircraft.

In both large passenger aircraft and small aeroplanes, all aviation systems are doubly protected. To ensure that this redundancy in handling does not become too complicated, developers are constantly working on the function and design of individual components.

The motivated ‘team of aviation enthusiasts’ at RS Flight Systems in Berg near Munich develops and produces avionics devices for 2 to 4-seater aircraft and helicopters. ‘We all grew up here with flying and have the vision of making this experience ever easier and safer,’ CTO Dr Matthias Weinzierl (front right on the cover photo together with the second company founder and CEO Maximilian Rommel) tells us.

Modern motors – more effort?
Highly efficient fuel-injected engines for small aircraft, such as those from the market leader BRP-Rotax from Austria, have been impressing customers for years with their enormous performance and fuel consumption reduction. However, these complex components also require a whole series of switching operations in order to test all functions before the aircraft takes off.

Where once 2 switches were sufficient for older aircraft engines, the pilot suddenly had to operate 8 of them. In addition to the effort involved, the risk of forgetting or confusing one became too high. As a result, RS Flight Systems introduced the Start Key Switch 9iS, a switch with a high level of logic that could be used to access all functions in 8 different switch positions. Undoubtedly a very space-saving variant, but for some users it was already too compact and they wanted more clarity. These parameters led the developers to create the SCU Front Panel V2.
