slowrotor, you're right about the hover efficiency. Nick's comparison is entirely accurate, and somewhat valid as it compares the V22 to what aircraft it would replace and the roles flown by that aircraft. However, I think most of us understand that the V22 shines when time and distance are critical factors rather than cargo weight, volume, or rate.
I looked at the numbers and set up different scenarios. The V22 did become a clear winner where we would expect it to shine. Of course, for both the -53 and the V22 I had to use glossy brochures to come up with numbers.
I didn't factor cost into it at all. I have no doubt the V22 will come up high on that one. I would like to know what it will cost the US to buy one more airframe, i.e. incremental cost without the developmental costs included.
I'm a bit of a V22 supporter, but then I tend to support new technology especially when it isn't my $$ (or ££) being spent.
Matthew.
