Thanks Spiney Norman -
I've now read your briefing - very helpful. I've also had a look at the AIP. I guess that given decent enough weather - (certainly not like this week!!) - the route is just OK given that the applicable requirement is to "alight clear."
By the way, I know that the low level route was in existence as long ago as 1965 but aligned more north/south than it is now. There was also a short link into Barton. I think a realignment took place a couple of years ago because of the new Manchester runway. The redesign seems to me to be much better than it was previously.
It seems that it is intended to be a visual route and so GPS (or NDB at Whitegate) should not really be relied on. I don't see how it could be sensibly used at night however???
Seems sensible to at the very least listen out on Manchester Approach radar frequency but I guess they don't really want calls if they can be avoided?
Sincerely
