Hi Neil
I cannot quite understand this, you are correct G-ELCH was generating warnings.
More interestingly, they start as bearingless, but later appear as positioned.
$PFLAA,1,4500,,18,1,407744!GELCH,,,,0.0,8*08
...
$PFLAA,3,8,11,21,1,407744!GELCH,53,-0.5,36,0.0,8*3C
you mention
Also, the aircraft has GDL90 and I used that as my PAw protocol, is that it?
What does that mean, the aircraft has GDL90 ?
The problem only occurs in the first flight, and not the second, load your tracks into here

Thx
