Bomber Aris:
I agree. We should be looking for technology to unlock our potential.
I was lucky enough to fly approaches to a hover with Nick several (i.e too many) years ago, and was quite impressed. We have the technology, but not the political will.
My only concern with a decelerating approach to a low vis / ceiling is that we're going to need to have guidance down to the ground, as there will be a point on the approach where even a Category A helicopter will be committed to land if an engine fails. But given the state of Differential GPS, this should not be a difficult thing to do.
The real question is why don't we have it in work now?
Ask the FAA.
Ask HAI.
Ask AHS.
Ask AOPA (well, maybe not them).
Ask the EMS people.
Ask the military (by the way, we've had man portable ILS systems since the early '70s- ever see one in use in the military?)
