Well I am not a pilot type but I would have to say that this machine does present a challenge to go along with it's new capabilities. I wondered about this myself and I thought it might be best as a two pilot machine with one helo type and one fixed wing type driver to cover both regimes.
It is clear that BA has taken the "make an airplane that flies like a helicopter" approach rather than making a helicopter that flies fast like an airplane. This to me is interesting considering Bell is a helicopter manufacturer although they do have roots deep in the airplane world. I wonder if the requirements would be the same if they had gone the other way. I guess we may find out with Sikorsky looking at the coaxial configuration again. Will they have the same crew issues with a high speed rotorcraft?
