Data Dad,
taken from Eurocontrol ACE Benchmark report 2007:
ATCO hours on duty (avarage per year)
AENA 1800
NATS 1434
DFS 1245
DSNA 1328
However I guess things may have change, or maybe you were not considering operational time hours only.
LH2,
I will not take this thread to another discusion about spanish ATC's value. We all now how it would end up.
Anyway, I'd like to remark that our Union has constantly demanded AENA to recruit new atcos for the last 10 years repeatedly. There's clear evidence in every single minute of our meetings with AENA, who has broken many agreements on the subject.
Of course spanish public opinion is far away from our side, but, I must say, I don't consider this forum represents precisely an easy audience. Please don't take it as an offence.
