Why do ATC insist on not publishing these handover agrements. 330 by exmor, 270 by liffey, 280 by otbed.etc etc. Pain in the arse on a trg flight. Things that need to be planned for on a trg flight need some form of reason. Just do it because it will happen isnt good trg technique. Espacially when it doesnt on occasion. Publish it , with caveats or it shouldnt be a requirement
Obviously you fly into Manchester fairly often, if you look at MACC's airspace (which is published) you will see that all of these restrictions are to get you into MACC's airspace. No point in working LACC or Scottish that close to Manch with the volume of other traffic around. They are there to ensure the best efficient use of airspace, not to pi$$ off pilots.
