I have made performance files for a DHC6 Otter (Dash 6) and they seem to work just fine, apart from the fact that when I am on approach, after the first flap call, which is fine, subsequent flap calls then come all together, all in a rush. I can't see why this should happen: on the last flight I was holding about 105kts, but got the final four flap calls (15, 20, 25,35) all within a few seconds, which should come at a lower speed one after the other.
I attach the log and my .uco file (had several goes at this before resorting to posting here) - if anyone can see what is going wrong!
I've never had this particular problem before.. I dare say something isn't set right, but I just can't make out what it is!
Thanks,
Martin
