Hi,

I have just received my 302A back from a barograph calibration and now
the flight logs that I download returns an error message 'Security
Fail'. It still gives me an igc file that I can up load to OLC but the
flight remains greyed out with a message that the 'log file not
valid' . I have messed with the turnpoint database since it came back
from R Track so I am not sure what it might be.

Any ideas?

My mdoel 20 gps/logger was just recently returned to Cambridge for
repair because I was getting the security failure. The files now
should as security when viewed with the Cambridge utility but OLC
still shows them as invalid.


That would be a different problem.

Looking at your file posted on OLC, it appears to be just a normal
..igc file, rather than the munged-up abomination required by OLC
when using a model 10, 20, or 25. You need to use a utility that
combines the .cai and the .igc into another file called .igc.

The flight analysis software packages can also do it automatically,
sometimes with patches required.
