IO540 often pontificates on subjects he knows nothing of. Like you I have flown many hundreds of rig NDB approaches in the grot to a minima most pilots would find surprising (200' and .75nm), and while GPS is great that needle on the Nav. display is a very useful tool, and like anyone who is taking their aviation as seriously as those who fly offshore I am a firm believer in having every nav aid, even an antique, working for me from take off to touchdown.
200' and 0.75nm over the sea is another thing, especially if you have a radar alt and pilot interpreted radar approaches????
You can fly a precision LPV approach down to ILS minimums these days, and every single platform could have one if they wished.
