I reckon the deck landing would be a trifle delicate in a bit of a sea. It was bad enough landing the Gazelle and Scout on the decks in a calm sea!!!!! Would that roof really take the weight of the R22, loaded with fuel and 2 pax????
I refuelled a Robinson R55 many moons ago. First problem, the MK bowser fuel nozzle didn't fit the cabs fuel tank opening. Soloution? The pilot fetched a plastic coffee cup from the cab, smashed a hole in the bottom and jammed it into the hole. The nozzle fitted and the cup worked like a funnel. Second problem, the bottom half of the plastic cup melted with the avtur into the tank! I warned the pilot of the situation but he was adamant it would work it's way through! Don't know the outcome, hopefully nothing!
