Forget the icing problem, that can be designed / de-iced out.
This is the thing to be more concerned about from the first report:
"In the event of a single engine failure, V-22 flight procedures require the pilot to transition to aircraft mode".
And if this isn't possible, such as on take-off from a restricted area?
Any info published yet on the Performance A / Class 1 requirements?
This aircraft CAN'T replace helicopters because it is specialised / optimised for the higher speed envelope, not the low speed environment where true helicopters will remain superior. It is like asking a greyhound to pull a heavy dog sleigh - it doesn't have the low speed grunt to replace the husky.
