Engine System Interface(ESI)

The heart of engine and aircraft systems.

* Suitable for Light Sports and Experimental Aircraft

T3000 skySuite product range supports our Experimental/LSA customers

T4000 skySuite product range supports our Certified customers

Designed for flexibility, the ESI supports a wide range of engine types and sensor inputs.

The Engine and Systems Interface (ESI) is the heart of engine and aircraft systems data management for integration with your skySuite System. It captures real-time information from your engine, fuel, electrical, and sensor systems and delivers it seamlessly to your cockpit displays.

With the ESI installed, pilots gain a complete picture of engine health, performance, and critical systems status – supporting safer, more efficient flight operations. 

Whether you’re upgrading or building new, the ESI delivers streamlined integration, reduced wiring complexity, and intelligent system awareness.
