Engine Interface Units

Aircraft Engine Interface Unit

The Engine Interface Unit (EIU) is a rack mounted avionics data acquisition device that collects multiple analog signals from the aircraft engines and converts them to digital format. Our EIU has the ability to processes multiple aircraft signals such as flight surface position, fuel quantity, autopilot drive, proximity sensors, plus several others. It outputs data over an industry standard ARINC 429 data bus that interfaces to a multifunctional cockpit display. Data is also output directly to the Flight Data Recorder via analog or data bus signals. The EIU features redundant signal processing to provide reliable data gathering and is capable of storing engine parameter data to aid in trend monitoring and exceedance tracking.
