The XTreme is a compact, multifunction electronic flight information system intended as a main flight instrument in smaller aircraft or as a backup/secondary flight instrument in larger aircraft.

The XTreme’s light weight, small size and high level of functionality makes it an excellent choice for all types of noncertified aircraft.
