Scuzi....we speak the same language.....
but I ask you think bigger......the reason that a clever person came up with SID's n STARs 50 years ago, is to reduce the same ATC patter over and over again. In London today we have, guess what, the same ATC patter over and over again, but it's headings.
You give a good example of aircraft seperation up the line. But, I say design SID's to take care of it.....make them SID A or SID B. Think outside the box, make SID's dynamic. Change from type A to type B depending on separation. Just a wild example, but something needs to be addressed. I don't know how to fix it, but guess what, it's somebody's job. He/she is paid a sh1t load of money to manage, and it's ignored. For me thats a sackable offence. If i was in charge there would have been change a long time ago.
Personally, i think heads should roll over the 'outdated airspace' issue in London. What do ATCO's think?
