Bring back FAM flights.
Or maybe crews could visit ATC units and tell them that 160 to 4 is unrealistic for that type of aircraft, and tell us what they can realistically do.
I was training a guy the other day and he had no idea that the BRt E145 reduces to 240kts below FL100, if he had known, his plan (which worked in the end after a lot of vectoring) would have been different. I knew because I've talked to the crews that fly them, would never get to the pointy end, but they came to see us and we talked.
Anybody know about EZY operational requirement for 250kts below FL100???
They are required to be 250kts below FL100 UNLESS specifically asked by ATC to keep high speed which they will and frequently do.
