Hello everybody,
the recent CVS update of Navaids/nav.dat.gz (R1.10, Dec 20) seems to
have introduced some broken lines which cause Atlas to quit during
loading the file. FlightGear, however, seems unaffected.
Most of the broken lines are localizers where only one ICAO code was
given while the file format specifies two (localizer identifier and
airport code).
I fixed this by doubling the airport code. That is probably wrong, but I
am not an expert on navaids, and it does fix the problem with Atlas.
Maybe someone who knows more about it can provide a better solution. The
corresponding lines are 12062, 12103, 12393, 13389, 14125, 14255, 14372.
One other error is in line 13123 where the subtype LOC-GS is given,
while Atlas only understands LDA-GS. The file format specifies neither
of them (only LDA and LOC), so I just changed it to LDA-GS.
Attached is a patch against the unzipped nav.dat containing these changes.
Regards,
Andreas
