I'm using the A318/A319, but unfortunately I noticed that with versions 188.8.131.52 and 184.108.40.206 there was a significant step backwards when flying STARS and Transitions.
LOWW29 --> EDDF07R
LUGE1C LUGEM DCT LNZ DCT SUBEN T161 ASPAT ASPA4E //DF644
I've flown this route four times in the last few days to verify this behavior.
With version 220.127.116.11, the A319 was able to fly the ASPA4/STAR profile without any problems.
Everything as it should be.
