I had a BA for 10 years and I don't think there are any real issues with hydraulics ! Yes , things get heavy when you get sub 10 knots and run on is better option if available but zero speed landings are quite possible if no other options . Also the sequence of buttons for hyd off testing are very precise and not too complicated even for me !!
My only issue with the type is the flimsy nature of the cockpit....I would rather hit the ground hard in any other type rather than a 350 ..even Robinsons are safer at that point !!!
