How many sectors around the world are single manned - at any time, day or night. What is ICAO or IFATCA policy?
I believe that there should not be 'single controllers on station' by policy of the above, but that is very different from single controllers doing different jobs. i.e. 6 controllers for 6 very different sectors with no co ratings/endorsements.
If it is so dangerous to work that way in the UK, what about the rest of Europe and the world? And what can be done about it?
