System of Aviation Modules

System of Aviation Modules (SAM) represents an unique open distributed aviation system that performs specific functions aboard an civil aircraft Ae270.

Each module integrates and automatically carries out specific functions aboard the plane thus increasing the comfort of the cockpit crew when operating and controlling the aircraft. The individual modules can operate independently. Alternatively they can be extended or grouped as required by the customer via a communication bus implemented by means of the CAN (Controller Area Network) serial communications interface standard and the HLP (Higher Layer Protocol) communication protocol within the CANaerospace standard. Individual modules can also communicate throught UART.

Each module also provides internal functions for module diagnostics that help to prevent emergency situations.

Modularity and openess of SAM allow its implementation into or cooperation with any other superior avionics system.

The SAM system is one of the first device in the world to use CAN with HLP Canaerospace standard certified for application in civil aviation.

Application

System of Aviation Modules (SAM) has been primarily developed for the use in civil aircraft Ae270 (dolnoplošný jednomotorový turbovrtulový víceúčelový transportní letoun), manufactured by Ibis Aerospace Ltd. However, its modularity and openess allows its integration into any other aviation system.

Ibis Aerospace is a joint-venture between Aero Vodochody (Czech Republic) and AIDC (Taiwan).
