Tim, Ian,

Is the GPS data file sequence checking / analysis software you mention
in your separate posts available to us? If all FDRs screw up their data
files occasionally, it might be very useful to have such software more
generally available to soaring pilots.

'Out-if-Sequence' B-records are not exactly unknown. Some time ago a
wrote a simple program to sequence check .IGC file and catch these.
Cambridge is not the only manufacturer to suffer from this either.

By all means email the files (CAI and IGC) to me and I will look at
them with analysis software that enables every fix to be looked at in
detail. Some analysis software uses its own algorithms, for instance
to average things out. This may mean that some anomalies in fixing are
not obvious. As someone else said, you can always look at the
B-records in the IGC file itself, but this is better done through
analysis software designed to intepret them individually.
