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, as well as a backup/control for the AHRS. If you do not select the SP-4 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

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

Upcoming functions (free software upgrade later this year): Basic GPS navigation (waypoints, routes, CDI (no moving map)), and Internal Autopilot (just add servos and connection module).

1 RDAC is required for engine functions to work.
