So what. The hell with 'calibrated to ICAO standards' - it's a published UK navaid and it is the
location which is used.
I can guarantee that if I told some air-trafficker that my next turning point was 'Shawbury' or 'SWB', he/she wouldn't sniffily reply that he/she didn't know where that was, because...
'...it's not in the bleedin' AIP'
No doubt there'll be NATS-apologists along.....
Told you so! NATS needs to help, not hinder.
