Interesting reading from all. I must declare I have an interest here too, as I have been told that the manual has the preferred routing for IFR flights around the London TMA. If this isn't the case, then I've lost a fair amount of interest (although curiousity in items is proportional to the level of restictions

)
If there is somewhere else I could find out about these preferred routes, particularly for aerodromes near but not in the TMA, could anyone be so kind as to provide vectors as to how to obtain them?
