Geoffersincornwall,
Do you update the training for this? Will Leonardo lift the oil cooler noises from the CVR so you can train pilots on an alternative to ditching from That noise combined with high temps? The QRH for high MGB temp is "land as soon as possible", but the general note applied to Transmission System Failure, of which the high temp is one, adds the proviso that "multiple indications" (there were none) or "abnormal noise and/or vibration" (there was that) changes the action to Land Immediately (ditch). Quite a burden on the pilots to differentiate.
Maybe an engineering guru like noooby can fill us in on the technical consequences of this kind of failure.
BTW, the QRH Engine Fire drill says "confirm", but the Rotorsim interpretation for that has always been for the pilots to simply check for the fire lights on the power levers, none of the Puma visual check of the engines with the eyebrow mirrors, or the 92 doing the same with the tail fin camera (or doing a flyby of a convenient rig). Fortunately the Fire Warning system, like the transmission, is quite reliable. Oh, and all types I've flown have some kind of "confirm" written into the engine fire procedure, at least on the operator ECL.
