Why not let 2 or more Helis land at the same time? The carrier is 3000 Times the size of the chopper, and the landing strip could accomodate 50 helis at once.

Helis have very limited fuel if you have 8 air vehicles trying to land all the choppers will run out of fuel before the first plane reached the elevator...

I had 2 helis land, it took over 5 minutes...
