Finally I have been able to sort out all of my problems. After around a total of 200 hundreds good landings with every FSX plane I completely understood what was making my APP crazy.
It was not the APP it was the ATC that above all on big hubs like NY Kennedy , Miami etc.. fires you hundreds nm away an at the end it also cancels the IFR ....
I then carefully browsed forums on internet and I discovored this is a well known SUPER HUGE bug of the ATC also known during ancient FS9 eras.
Therefore, is there a way to annihilate it in some ways ? Is it enough to ignore I know it but every single time I may disturbed by it until I change the radio frq to shut the bastard off.
Is there a mod o a third part software that replaces the M$ ridicolous error ?
Thanks in advance mates
