The new overspeed warning + stricter requirements for expert have helped, but now the main issue is ridiculous speeds between FL100 and FL300 - today I was overtaken by someone at FL190 travelling at 503kts gs.
There was no wind and in reality the aircraft would break up. Means that when you climb at a realistic speed you have people entering conflict behind you because of their ridiculous speed -forcing you to take evasive action.
Not sure what solution would help prevent this?
Approach, Departure, and Center controllers can limit speeds and send speed commands, so, especially for approach, they can regulate speeds for approaches. Also, with global coming out soon, we might see some for of center controllers regulating speeds to keep organization
