Introducing the XTreme EFIS…

What is it?
The XTreme EFIS is an affordable mini EFIS. It can be configured as a PFD (with AHRS sensors added), and/or an engine monitor (with RDAC added). It includes a GPS receiver that is used to provide ground speed and range information, a basic CDI navigator, and as a backup/control for the AHRS. If you do not select the SP-7 attitude sensor, you can still have a GPS-derived bank angle display!


You can use it as…

  • Primary EFIS
  • Backup EFIS
  • Engine Monitor
  • EFIS/Engine Monitor
  • Basic GPS Navigator with CDI (no moving map)
  • 2-Axis Autopilot

Some might use it for just 1 function, or you could use all functions!

Note: You can share the AHRS sensor data between several XTreme EFIS units, and you can share the RDAC engine data between several XTreme EFIS units or a mixture of XTreme EFIS units and XTreme EMS units. With the XTreme EMS you can add a 2nd display for engine-only at little expense!

The XTreme EFIS is a mini-EFIS unit based on a 4.3″ sunlight readable, wide viewing angle, high resolution LCD display. It integrates an SD card reader (for software updates and for flight data recorder), 5 function buttons, a rotary control and a basic GPS navigator.

It can be connected to standard MGL Avionics AHRS sensors and RDAC (engine monitor) boxes. It also integrates a CAN Aerospace compatible communications interface that will be used with future versions of MGL Avionics sensors. Standard RS-232 ports are also available.

The XTreme is designed to fit a standard 3 1/8″ round instrument hole. The body is located off-center allowing the unit to replace instruments on the right side of a standard 6-pack configuration or any other location that currently occupies two instruments.

Due to the light weight and very low mounting depth no complicated mounting brackets or trays are needed. Power use is low and operation from much less than 12V to around 28V is fully supported.
