Does it have ELS?
I have looked at this thread for a while and as an engineer I am puzzled by one major point, Sikorsky designed Seakings are operated by UK armed forces with ELS fitted to the main gearboxes. This was due to need for aircrew to be able to land the thing if they lost all gearbox oil pressure and it does work, not 1/2 hour fly dry, but good enough for most situations. If the idea that the Seaking could lose all it's gearbox oil is not "remote" or "negligible" ( first hand knowledge!), why is it that, from what I've read here, by some very knowledgable people, the S92 has NO ELS? It seems to be like a car manufacturer inventing the seatbelt and then not fitting it in the latest model! If I missed the answer to my puzzle, I apologise and await your scorn! (newbie flaming)
