It does not sound like an inertial solution, but rather a more sophisticated pneumatic and magnetic calculation. It will be interesting to compare it to a Butterfly. In their paper, they erroneously claim that no instant wind calculation method existed before theirs - marketing I guess.

Has anyone any experience yet with the new Lxnav Hawk Wind program? Sounds superficially to me like it might be an alternative to the Butterfly wind solution which is no longer readily available. And this program seems to avoid some of the Butterfly installation challenges?
The LXNAV LX8xxx and LX9xxx have all of the inertial sensors (accelerometers and rate gyros) in the unit. You can purchase the artificial horizon AHRS option as a (somewhat expensive) software key:
