Come on - someone must have the ATC bible in the attic! What DOES 'descend' mean in the UK? Can it be expanded to 'now'/'when ready'/'pilots' discretion'/etc within the CAP terminology?
Knowing this will help us IN THE UK at least - we will still have to juggle the foreign 'balls' though, but maybe we can take a bit of steam out of the kettle here?
Any gurus know from where Jepps and Thales get their info for airfield plates?
