How come the published radials for way points differ to what you would read off the map. For example in the Pooleys guide EGAE is given as "BEL 117.2 314 39" which I interpret as saying that EGAE is 314 degrees magnetic from the Belfast VOR with a distance of 39miles. Yet if you were to plot that line on the map you would get 311 magnetic.
How odd, my 2007 Pooleys says, on p376: "BEL 117.20
311 39.5"
Also, I might be able to help with your confusion here:
Dungiven is a VRP to the south east and it is also used for an instrument app. The radial is shown as R312 from BEL but if you measure it you'll find that it's actually 308.
Dungiven VRP and DUNGV holding fix are not the same place:
VRP (per Pooleys): N54 55.70 W006 55.50
DUNGV (per Aerad): N54 53.73 W006 47.40
