Third-party compatibility

We have the only AHRS in the industry that can operate unaided
in the event of loss of airspeed, GPS or magnetic heading.

Our EGT Time History graph makes it easy to distinguish between engine problems affecting one cylinder, or the entire engine. This distinction could be essential when making decisions in response to engine problems.
