As far as I know B3 is dual hydraulic system, I know the ones I've flown are. The couple the company I work for had were for sure. Made Hyd failure training pretty redundant. When I did my B3 training a few years back we didn't even do Hyd. Failure training. Mind you we have a fleet of B2 and BA and very much emphasis is put on this failure. Fact I did my B2 re currency a couple evenings ago, and knew for sure the horn was going to go off en route from base to the airport. Yep I guessed right. We do lots of training to confined areas, no run on landings for hydraulics off. Run on landings at an airport, not an option some of the places we work.....
