Here we go again. Vali-ewa.exe only checks the hash
of the file against the G line, if there are no datum
records in the file your OO or the NAC's badge secretary
should reject the claim.


Hmm, and why does it print this info same cases?

'The following fixes are not recorded as being relative
to the WGS84
geodetic datum. Care should be taken that these fixes
are not used
to validate the flight.

22 fixes from 05-04-04 11:22:59 UTC to 05-04-04
11:24:02 UTC inclusive.

EW Flight Recorder security checks indicate file '544E7AM3.igc'
is VALID.'

That's interesting, it would appear I was wrong. Are
you saying that file was generated with a 'mouse GPS'
and contains more than 22 fixes?

I was under the impression the datum record would only
be generated by Garmin's proprietary PGRMM sentence.
My 'mouse GPS', based on the SiRF chipset definitely
can't output this sentence.

I'm afraid I can't do any testing, as I haven't owned
an EW for nearly four years now. If you've got sample
files, feel free to send me a copy (I do have some
old files generated with an IGC upgraded EW model B
and a GPS from the approved list).
