At the risk of rehashing the run dry debate, what is the "record" for longest run dry time? Asking about real world examples- not bench testing. IIRC the S-92 tragedy took @11 minutes to unfold. Any real 101 examples or others? We have 30-minute requirments that the manufactures have been certified to and they say they can meet. I do recognize that loss of all oil is an immediate emergency, and no-one would push on casually- just trying to hear some real world examples of the system working as advertised.
