Dick,
You talk of approach rated Enroute controllers, which is fine, however the WLM airspace in question will be introduced on the 19th of November which is not enough time to actually give the controllers involved an approach rating, even if ASA did have the training capacity and staff numbers to do so (which they don't). Are you suggesting that E down to A045 requires an approach rating?
As I have outlined above, there are some major restrictions in the controller tools available to process traffic in and out of WLM. The Office of Airspace Regulation has imposed the airspace on Airservices full well knowing that an Approach rating is necessary to run the airspace for the phases of flight encountered, but they have set a date that will not allow it to happen.
My question that is the subject of this thread is "why?"
