Good to see the banter is still flying around here!
A quick question for you learned gentlement concerning S92 hydraulic's...
In the event of of leak in one of the hydraulic systems the LDI system (with the reservoir at 50%) will close the tail rotor isolation valve. What happens if there is a leak in the other system? I had heard, and I'm happy to be corrected (very happy in fact!), that both systems isolation valves will open and close continually until both hydraulic systems are dry which happens in a very short period of time. So if you had a leak on the tail rotor side of the valves in both systems then you have no way of stopping it dumping the fluid.
Incidentally, one S92 had a RIPS failure halfway across the Scottish Mountains so I can see the argument for a positive temperature band but I'd still rather have RIPS than not.
