Just tried to do a flight from EGLL to EDDF on Monday, 12th of April 09:00Z take off time with life weather. At CRZ LVL 390 my FBW A320 got smashed around every time the sim switched to the next weather station. Deviation of appr. 800ft from CRZ ALT kept the AP busy. Every time the ALT DEV horn sounded and the AP tried to follow with up to 1800ft/min climb or descend. The best plane doesn’t make sense in a sim like this. Topic is as old as this thread at least. xPlane can handle this since years/ever. Boy oh boy this sim is still in Alpha stage about a year from release. Very frustrating looking at the prize. Still stops me from buying any addons.
