Leah and I are down here at Chilhowee for a VSA rally and had an enjoyable flight in the Ka7 today attempting a silver altitude gain for the highly sought after VSA Silver Coin. Unfortunately by the time we were hot, tired, hungry, in pain, and had to pee we hadn't quite made the gain. I found the trace for my FlywithCE interesting though. We released about 2400 MSL and I soon remembered that I hadn't turned on the FlywithCE. So I turned it on at about 3000 I think. Check out the trace: http://www.onlinecontest.org/olc-2.0...l?dsId=2421969
It seems that the FlywithCE was trying to insist that I had started on the ground, then realized that wasn't right, and attempted to correct for it by jumping the altitude up about 3000 feet. If it had just recorded the actual altitude it would've been fine. I would've had a trace starting in mid-air, right where I turned on the recorder.
The IGC decided that position recorders like the FlywithCE will be allowed for Silver and Gold altitude gain after this fall. Would I be able to claim this obviously bogus trace for Silver Altitude? (evil grin). I suspect this is a problem associated with not turning the thing on until mid flight but dang shouldn't it just record what the actual position is???
That seems concerning, hopefully folks from FlywithCE, and SSA and IGC will look at this. There is nothing in the IGC file that seems to explain this.. Its just recording apparently normal 3D fixes. Does the IGC file direct from the device/logbook program have anything unusual looking in it?

What is also interesting is my reading of current FAI rules is there is no clear language/simple requirement for the OO and/or pilot to ensure the flight recorder/logger is actually turned on before flight. The OO required to do things like ensure the device is in the glider, attached, not tamperable (I don't read turning on as tampering) and to independently verify the take off an departure time - but so what if the OO knows the take off time, it the recorder was not turned on. Sure you expect the OO to do their job here and note the flight recorder in-fligh start discrepancy. But what then does the NAC examiner/badge person do? If (like I hope there is) there is a requirement for the FR to be on before flight please provide the rule number.
Thanks
