Firstly a big OK! to Scroggs and the ATC guys and girls for thrashing this one out. It really does restore faith in pprune after all the c**p we sometimes get on other forums.
What would be really useful would be a list of waypoints and altitude restrictions that are NOT published in our documentation - we all know about 260 Margo (we only ask because it is normally below economic height there!), 200 Tebra etc, but there are a stack of others that Thales/Aerad (or whatever they are today) do not print.
Europe has its own luxurious set of 'secrets' which you get to know after a few goes (eg level 290 30 before TOP) into Italian airspace). It would be nice to get those too!
Perhaps our friendly forum mod could put up a 'sticky' for contributions?
As Scroggs says, saving 1T out of a total of 10T sounds like nothing, but as he points out, it is a big chunk of what we actually have to play with, and an idea of the various restrictions would give us a little hammer to hit the planners with as they get ever tighter and tighter on our reserves?
