The V-22 in helicopter mode flies like a CH-47 or CH-46 tandem. It
hovers, turns, and maneuvers like a helicopter. Fly-by-wire controls
smooth the transition from helo to airplane mode. That said, the
proprotors were cropped to fit Marine amphibious assault ships, so the
V-22 has higher disk loading than an optimized helicopter. That means
it can't carry as much as efficiently as a tandem rotor of the same
size/weight. A V-22 would not be an efficient aircraft for Vertical
Replenishment with lots of hovering. Autorotation capability won't be
as good as a helicopter -- hopefully, you don't have to do it. The
tilt rotor can however cover long distances as an airplane faster and
more efficiently than a helicopter, and that's the payoff.
