Some of the sectors already have a workload that would allow the safer and more professional service at no cost increase.
My underlining
What about the many sectors that don't? If you increase the controller workload, wouldn't things get less safe? Or would you just employ more ATC, increasing costs, which the industry does not want.
From AsA's site: 1000 ATC handling 4,000,000 flts a year (11000 per day) - 1 ATC for 11 flts/day
From FAA's site: 15000 ATC handling 87000 flts per day - 1 ATC for 5.8 flts/day
So you could argue that our guys already handle twice the traffic per head than the US ones do. Maybe they have enough to do now. Maybe if we doubled ATC numbers (at no cost of course) so that handling levels were comparable, you could get a similar service, because it seems that's how many are needed to provide it. I'm sure if the FAA could get away with needing only 7500 ATC they would.
