If the powers that be implement the AAIB recommendations then I agree by default my concerns and the concerns of many others will be addressed. The issue then will be all the other Airfields with an NDB off the Airfield and only one dme. Liverpool RW 27 as an example - exactly the same latent error. Unlike Dundee, good radar, highly alert ATC ensuring no Aircraft overshoots into Manchester Airspace and no high ground to bite you.
