Gonzo- as I said above, 2hrs on sector very rarely happens and if so usually for extenuating circumstances. Hour and a half on then 30 mins break all day, all cycle certainly not unusual though.
The MACC enhanced relief agreements dictate that for most of the MACC sectors, 1.5 hours on sector is the max for large parts of the day (or for some of the sectors ALL day) ....which again seems to support the argument that high sector traffic levels and/or complexity at MACC are not a myth?
As for sector complexity being rated 5th in Europe....afraid I don't have the personnal experience across Europen centres/sectors to comment.....however I 'm assuming that Eurocontrol (if indeed it was them who compiled the report) put a bit of thought into the process and didn't just draw names of sectors/centres out of a hat.
