As far as printed map accuracy and navigating by the same, if you add the possible errors from printing to the sort of accuracy you get with visual nav, I think it would be in the order of miles rather than yards.

Yes CAT does use it but I did stipulate "handheld" as that is what most will use, panel mounted and approved are the only ones used by CAS and some more elaborate aircraft and as for the ANO quip that was what the poster referred to for the only definition of where the boundary's are.
But I will stick with the argument that the charts are official publications and therefore considered accurate unless notified about errors.

Not only are towns never yellow and most of the countryside not white, but also think of the parallax error between the drawn line on the waxed surface and the actual print on the paper, due to varying wax thickness and offset ocular angle.
It's a wonder we manage to get anywhere at all with those things.

I quite agree. CAA maps are crap. They never bear any resemblance to the ground I'm flying over.
As for them not resembling the ground I believe the topo is from O/S so they are the ones at fault?

Yes there is a plethora of aircraft wandering around the sky with pilots trying to get the sextant readings right before the spherical trigonometry calcs and tables checked are done before pos is found.
PS: Scooby Doo it's "Stansted" not "Stanstead"

And some can.
The buggers don't even paint a magenta line on the ground.

When flying along the south coast I made it clear in my initial call that I was going to be keeping clear of controlled airspace (they sounded busy, the small dogleg didn't bother me as I was out for an enjoyable bimble). As I turned over Sandbanks I was told that if I wanted to 'drift in' to CAS they wouldn't have a problem so long as I stayed below 2,000 feet.
