Thankyou for the reply, in the meantime should I report the bugs I have found or have they pretty much been documented already?
For instance I have found the following items which I believe to be errors...
Leena4 arrival can cause Airplane Not Handled error. On the SXC-IPNAW leg of the arrival flights will generate an Airplane Not Handled error if they aren't given a turn shortly before reaching IPNAW.
Gorman and Ventura SID's both appear to have a leg in the departure route marked as "Target Marker Only" causing flights to miss turns.
Planes can be sent to the tower frequency multiple times for bonus points.
In the meantime thankyou for creating this wonderful sim, I'll likely pickup NY next and will be looking forward to seeing KORD in the future.
