Ok, the Hyd 1 has a subsystem, right? Which can be isolated in case of leaks so the aforementioned can be utilized. The EP keeps the Hyd 2 alive for flight controls and emergency breaks and landing gear in case of pressure below threshold. But what happens if Hyd 2 has a leak? The EP wont be able to keep up and you will lose flight controls. I know that wont happen, but how is it constructed?
