Shy,
If I use a VOR/DME approach....normally the Missed Approach usually has me trodding off for a hold at the VOR, some intersection, or a radial and DME distance.
Now how does that differ from GPS?
In your view I take it you differentiate between NDB's, VOR's and GPS for some reason. Are they not all the same concept....navigation using some sort of electronic means?
If we lowly country bumpkins can overlay a GPS approach on a VOR or NDB approach including the missed approach.....why not the UK?
I will bet you a donut to a dog dropping....you can hold the stakes in your mouth....and I will wager that a GPS approach without WAAS is still much more accurate than the VOR approach and for much...much...more accurate than any NDB approach.
