Speaking as somebody who benefits from the rather odd situation at TC of everyone being on the same Band 5 money, I can see where your comments are coming from. I'm sure the company would save a fortune if respective approach sectors were paid the equivalent of their tower counterparts.
Unfortunately, I don't think you'd ever get that to stick now. Also, you'd have to offer people the opportunity to train on higher paid sectors to improve their pay....not a problem for me personally, I'd be more than happy to try and elevate my Band 4 status to Band 5.
