Introduction

The XTreme-EMS is a compact universal engine monitoring system. The XTreme-EMS, which fits a standard 3 1/8”
(80mm) instrument panel hole, contains all the necessary functionality to replace several engine monitoring instruments.

All information is displayed in an easy to read format on a high resolution wide viewing angle 4.3” 1000cd/m2 sunlight
readable color display.

All engine sensors are connected to a RDAC (Remote data acquisition unit) which is normally mounted behind the firewall
of the aircraft and then just a simple CAN communication link is necessary to connect the XTreme-EMS to the RDAC.

The XTreme-EMS light weight, small size and high level of functionality makes it an excellent choice for all types of non-
certified aircraft.
