Hello- one of our aircraft, at #2 prop, I always find atmospheric sump empty that means I don't find any touch of Hyd with Dipstick when SVC propeller. On the other hand pressurized sump remain full. It is very confusing for me. Any one can tell me why this happen? What is other best and easy way to check Hyd level except atmospheric sump? Thanks
