Definitely not another windbag. It was a very good and reasoned video. Many have been saying for years that the "porting" brings over the same problems again and again. And PMDG ignore it!
Rebuilt from the ground up? Definitely not. And the Legacy Code left in by an earlier developer? "HERE WE TUNE LIKE AMATEURS" sums it all up for me. They are no better than another developer who willingly supplied their software to include spyware. PMDG are a dinosaur and MSFS has moved on.
I left EGCC about 45 minutes ago in the Ini A359 real weather. Currently (TAT) -31C, (SAT) -61C and (ISA) -5C.
Not sure what your problem could be? It is posibly a PMDG problem unless you have an external weather programme overriding MSFS2024 real time weather.
