Scott, our core sectors can be split, ie. Bex and my airspace is 2 validations (our minimum requirement) but could be split into 7 different radar positions (if they ever wrote the procedures!!), normally 5 during the summer. Some of our controllers hold a third validation, which can be from 2 to an extra 4 radar positions, again dependant on which bit is done.
Thread drift alert(!) but maybe people who do extra sectors should think about rescinding their validation if the management keep hacking away at manpower/pensions etc.
ukatco_535, its already happenning at Swanwick is quite a big way.........
