I have noted that my downloaded data has some mis-information in it recently and I'm try to figure out how it gets there. In the Longitude and Latitude it is inserting the following coordinates 39.06755 -94.89767, which puts me in Kansas for about 75 seconds at a time. I haven't determined in how many of the downloads (flights) it has occurred but it is not all of them but seems to be in most of the recent ones. I think it is only occurring once per flight but I haven't spent the time yet to find out the frequency.
Is it the GPS or the AFS. I have an AFS GPS and GNS 450W connected.
I tried to add a sample file but your size limitation is pretty small. Send me an email address if you would like a sample.
Thanks,
Nick
