Can some of you 135 Pilots tell us what would have been seen on the Caution Panel and other indications as the full level began to decrease towards empty in the Supply Tanks. Isn't there a Warning Horn that sounds at some point and either you disable it for a few minutes with a push of a button or you have to listen to it bleat away? Even if Disabled....doesn't it return over and over again until the aircraft is shutdown?
If I am understanding what I am being told....there are lots of indications that would give One every encouragement to land the Helicopter...including one engine flaming out within (in theory) three to four minutes before the last engine flamed out due to lack of Fuel.
If so....confronted with all of those indications....would not a precautionary landing be one of the proper options?
