Dear USRC,

Should you not IMMEDIATELY require a special US version of the LXNAV firmware for LXNAV 8000, 8080 and 9000 Flight Computers (as IS now required for pilots using the butterfly vario, LK8000 and XCsoar)?

The rules commitee has CLEARLY established precedent for the other "offending" systems of far less capability. As such only a special US rules firmware can eliminate the risk of cheating.

The LXNAV Artificial Horizon product is a highly capable system which is easily accessible to the contest pilot. As shown off in the video advertisement (see first post in thread) the LXNAV AH funtionality is the "real deal" complete with a fixed installation module, calibrated real spinning gyros, etc. It will be highly accurate and capable of accurate cloud flying.

Astonishingly the USRC has not required the manufacturer of this specific system, LXNAV, to provide its US contest pilot customers with a US rules compliant firmware version which ensures the functiinality is impossible to use? Butterfly was required (asked) to provide this kind of US rules "compliant" firmware very early on and Butterfly has the exactly same level of AH technology.

Even LK8000 and XCsoar have been "required" (forced) to build US rules compliant software versions just weeks ago dispite the fact that accurate IMC flight (let alone safe) is literally IMPOSSIBLE with their unfixed, uncalibrated, highly unreliable mobile based electronic gyro's which are designed for "1g" gaming and not contest level flight as Butterfly and LXNAVs systems are specifically designed for.

Sincerely,

Sean
