The database is taken from the site

Brisbane

a) so you can easily check - just copy the coordinates eg 51.4649, -0.486772 into the google map window (put a space after the comma, otherwise there will be an error format)
b) see above
с) I compare the datum WGS-84 with local (ED50, PUK42 etc)
d) I did not say this, quite the opposite.
All troubles in the absence of visibility, but if the pilot stubbornly wants to land the aircraft only on the GPS, he must know what he can expect.
OK, so you have demonstrated that a crowd-sourced set of airfield/runway data isn't particularly accurate. That's hardly a surprise.
Do you have any evidence that stubborn pilots are actually using this data for precision approaches?
I'm struggling to see how this is a real-world (npi) problem.
