Smaket,
All due to the loss of direct tracking on the outbound SID and also a required (BIG) reduction in speed on the return STAR.
I only deal in FACTS. Latest changes = increase in $$$ to operators. E has resulted in less flexibility for the controllers = more delays and hence higher costs to operators. I hope that Airservices is seeing a bigger decrease in costs....
Have a nice life
