Interesting?
First off - using 'dive & drive', steps & level MDAs to MAP etc can be very hairy in a wide-body, the pitch changes are horrendous, even if you're name is Chuck with a 'Y'. Not nice in the sim and even less nice with 200, 300, 400+ trusting souls on board. Piece of cake in a small aircraft with in-line thrust engines though.
2: Treating MDA as a DA or DH is definitely fail material in NZ. The lag of the go around, especially with high by-pass fans, means you sink below MDA! Get out of that one Bloggs!
And, finally, a true story:
Some years ago I was going into Hong Kong when Kai Tak (ah!! the nostalgia) was the joint. The IGS (off-set ILS) was U/S and the favoured approach was a TNDB across HK Harbour AT NIGHT - stirring stuff! Not long after we checked in with HK ATC a United jet called up and when advised of the approach to be flown there was a 'stand-by' followed shortly by a request for vectors to CKS in Taiwan as he "...didn't have that approach in the can."
There was some harrumpphing on my flight deck until it was pointed out that he was probably the most professional pilot in the area that night.
We got in on our TNDB at night OK, but I still wonder...
