I'm sure I've landed that Gazelle on that trolley a few times. There were two
Dark blue ones in Scotland I flew off similar trollies. The one in the image had an ifr panel which obscured the view a bit.
I also used to fly an R44 out of an exposed site that had a trolley and sometimes on return if the wind was strong from an unfavourable direction I had to land on the grass. Shut down to reposition the trolley then start up and put the aircraft on the trolley. So watch out with fixed tracks that you don't get stuffed by a bad wind and try to land out of limits for you and or the helicopter. Must admit I never liked the trollies.
