Yes, at the moment NATS have more controllers than they need but they also have a high attrition rate what with retirements, VRs and leavers. Historically NATS staffing has gone through peaks and troughs, just now we are in a peak and numbers through the college are low. I suspect that possibly next year NATS will realise that they are getting short again and the college throughput will ramp up. Although on the airports side this would also depend on pending contract renewals which I'm not really up to speed on.
