The next-generation gearbox will also feature an automatic oil-cooler bypass switch, unipleat oil filter and improved durability with redundant scavenge and an auxiliary/emergency lubrication system. “The aircraft’s gearbox today already has a lot of redundancy,” Elani said. “We’re adding to that to further improve safety.”
Visual and aural warnings of a drop in oil pressure or a failed oil pump indicator will help pilots and crew in the decision-making process.
so an input module problem can cause a loss of oil and oil pressure so that the engine has to be brought to idle, the bypass to the cooler automatically operates leading to both engine input modules overheating??
Wouldn't be fun further out to sea IMC!
How much longer would it have taken to drop the oil pressure enough for them to ditch?
Surely a system with lots of redundancy would allow continued ops on one engine without problems?
Please shout all you like but I struggle to see how this is a well designed MRGB.
