I don't think so, the width of the Wasp class (31.8m) and the America class (32m) are referred to the beam at waterline, therefore the width of the flightdeck (without the elevator) of these three LHD should be relative the same.
Blimey, how stupid of me to jump to conclusions.
Alright, i think its pretty accurate USS wasp flight deck is 118ft(35.9m)
So 075 flight deck is just as wide if not a bit wider than USS Wasp. Still, the largest thing to fly off its deck for atleast a decade would be Z-18,20, not Chinook,Osprey or F35, so space shouldn't be an issue.
