Seems very shortsighted. Although if you are a cynic, it may make more sense. At the moment we are led to believe that NSL units are manned at a not too bad level. At the same time, most NSL units, especially the regional ones, are going through reviews to drive more efficiency and maybe even reduce the required ATCO numbers.
So, we have an "ok" (from a management viewpoint) level of staffing. And going forward we will be more efficient with WPs etc. Ergo, we don't need ADI trainees, so we cancel courses. This obviously doesn't take into account sickness, retirements, resignations, medical lossses, but then, they are management, we can't expect them to plan ahead!
Fast forward to when the traffic picks up, and those retirements etc have happened. We now need a good few ADI trainees. But alas the college hasn't been doing too much ADI training of late and isn't geared up for a large throughput. So as an interim measure it can be outsourced. And that (or more importantly what we are seeing now) is the beginning of the end for ADI training at Hurn.
But then again maybe I'm just a cynic. Whatever, this is yet another shortsighted move by management with short term gains and very little thought for the future. But are we surprised?
