Soggy, totally agree with what you are saying - dont know if I am reading posts wrong but seems people think I am advocating flying at full tolerance without correcting??? I fully agree with what you are saying about correcting so lets put that one to bed straight away. Intersting enough the FAA doc given states to 3/4 FSD and does not make any ascertion about correcting - merely dont drop below the DH - WEIRD!!!!
Tom, the point I am making about knowing where you are on the ILS meant in relation to Above/Below - Left/Right of the GS/Loc. If you want to know EXACTLY where are you WILL need DME (assuming no fancy GPS) as everything else is just guesswork otherwise.
I was taken right down to 50' on my IRT by the examiner to see if I could hold it. And yes I passed
Thanks for the discussion chaps!
