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.

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? I don't think it uses magnetic sensing, as it does not require the optional compass. So, it's all inertial and GPS, and I think doing it without a compass was an important goal. 990eur for wind equal to the Butterfly, and a AHRS, is at reasonable price for me. A separate AHRS is in the $800-$1000 range, so I'd bet getting the Hawk features for about $200-$400 dollars with the Hawk/AHRS. -- Eric Greenwell - USA - "A Guide to Self-launching Sailplane Operation" https://sites.google.com/site/motorg...ad-the-guide-1 The HAWK article referenced on the LXNAV website makes it very clear that it doesn't use magnetic sensing and why: https://gliding.lxnav.com/news/segel...magazines-eng/ Except for people with a Butterfly vario already installed that vario is now history so for the rest of us there isn't much value in comparing the two systems. |
