I thought that I would check for myself, and had no problems flying the NDB approach. Flying the cat c and d I turned base at 9dme and intercepted the glide slope at 7.2dme 3000 ft qnh just as the chart requires.
Two things, however, I was wrong when I said we had used the default ILS at EGNM, as the default has the wrong frequency and had to be replaced. The other thing is that since the airfield was made the NDB frequency has been changed to 402.5, so I will make a new file with the new frequency and upload it in an hour or so to the VFR Scenery vol 3 zip on the UK2000 web site AFCAD page.
Edit: Flying a practice NDB approach you shouldn't be looking out of the window!
