G'day
keithl, I don't know why there seems to be such a problem with this because ICAO has issued standards for the dimensions of enroute protection area in Pans Ops. We've issued our standards for enroute dimensions in CAR Part 91 of our Civil Aviation Rules and have also issued advice in the form of Advisory Circulars.
This is because we understand that our published, formal route network may not suit everyone. Thus, we've provided fairly extensive guidance material that allows operators to use the same standards to work out LSALT for any route that isn't covered by our network.
This has always been the case here (i.e. a Third World Country), so I don't know why the UK has a problem with providing the same sort of information. The very little I know about the UK CAA suggests that they might wish to use their own standards, in preference to the recommendations provided by ICAO in Pans Ops. I don't have a problem with them doing that, but they really should publish the criteria so that everyone under their control is singing from the same hymn book page.
Have I missed something here?
