Imposition of Speed Control
I think controllers need a greater awareness of individual aircraft operating characteristics before being given the draconian power to impose speed control. I know that many modern "scopes" look like a video computer game with lots of toys, and an unfortunate side-effect is a kind of detachment from reality with the real world. We really do need a proper FAM-flight scheme to cover this. There is no shortage of money in NATS for endless management courses, I only wish there could be quarter as much effort spent on service delivery knowledge for the shop-floor controller. What few by-the-back-door flights that are available are unofficial.....and we have to pay our own way on our days off.
