Okay I've checked default PMDG livery plane and I see that hydraulic thing, but not in my ryanair livery provided from you. I am at intro manual but can not find the solution for my problem
Had the same problem, solved!! 1. make an experiment with fsuipc version, 2. but I think helped me installation SB4 on C partition, earlier I installed in FSX folder and that was a fault.
