Lookatthesky,
Can of worms indeed.It's the building the counts,not necessarily the job that is done.Good example Luton radar,Band 5 v Aberdeen Radar,Band 2.
Aberdeen is as busy,if not busier.It has more airspace,a much larger variety of traffic,work departures and work in Class G all the time.Now the Band 5 boys will leap up and down saying they have to do another sector.Well we have to do the Tower.Probably one of the more complex I can think of.
I would be interested if someone can explain the logic,because I've been waiting for an answer for 17 years.
