Pilot Pete,
Thanks a mill! I'm back on track again I think!
Sjakie, as I understand it, published altitudes on an approach are minimum altitudes (unless mandatory is specifically indicated). Therefore, you are not obliged to be at the specified altitude at a particular point and can quite legitamitely remain above any altitudes on the chart. Intercepting from 6500' would be legitimate from a CDA point of view, even though the chart may show glideslope intercept at 9D for example. However, glideslope coverage is not guaranteed at the sort of range you would need to be at when intercepting from 6500', so while it's not necessarily illegal, you should really be descending to the published altitude and then intercept from there.
However, I may just be completely wrong!!!!
