As yet there is not enough detail on the maps in the GPSs on the hill to determine if the goal area has safe landings etc.

In years gone by the panel boughrt a lot of OS maps that are still carried about in a big box. When we landed we used to come back and stick pins in them and then measure who got where with a piece of string.

I haven't been to a comp yet, but it strikes me that it would be easier for international competitors to deal purely with WGS84 and decimal degrees etc.. rather than muck about switching between formats.
I don't see that it would be difficult for comp organisers to convert their turnpoints from OSGB to WGS84 for presentation as the comp pilots' turnpoints even if they deal with the turnpoints themselves as OSGB format.
Is OSGB used for posterity?
