Thanks to all of you who are doing this work on our behalf! I've already mailed in my ballot, but am curious on how the GPS rule will be interpreted, assuming it passes. I'm particularly interested in the Velocitek SC-1 because I have one. The rule makes it pretty clear that compass and speed modes would be acceptable, and the countdown timer should be no problem.
I assume Start-Line mode is outlawed because it's a position measurement based on two GPS waypoints.
I assume the Tactical Heading mode is allowed, since it's just doing the arithmetic to subtract a manually preset wind direction and is providing only compass information similar to a tactical compass like Tacktick.
I'm left wondering about VMG mode, which simply displays the product of speed and the cosine of tactical heading. Allowed or outlawed? It's not prohibited under article OD-VI since it doesn't use electronically gathered wind data, just a manually set estimate of wind direction.
Did these questions get addressed somewhere already?
Cheers,
Rick Sellens
