Yes, I know, and my post was intended to help them learn.

The title is "Catastrophic Oil Leak Detection," which I interpret as all of the oil leaving in a matter of seconds. Doesn't matter how inaccurate the oil pressure gauge is, as long as it indicates zero if there's no oil pressure.From what I can recall, it was mentioned at the meeting that the oil gauges in older aircraft are often inaccurate, and reliable readings can only be obtained after landing, following a flight.
Don't some engine monitors already do that? Of course, by the time you get the alarm it's too late...What might be of more use is an annunciator, not a second gauge. An audible warning in the headset.

If the engine goes from eight quarts to zero quarts in five seconds, the drop in pressure would be obvious.

Some older jets had remote engine oil level sight glasses in the cockpit to check static levels but some had issues as there were ADs issued to check oil levels at the engine to verify the cockpit level on a regular basis. But as you stated wouldn't help during engine ops.Oil level gauges exist (though I've never seen one on an airplane),
There are standalone warning engine oil warning systems used in some aircraft that would illuminate before oil levels would get to zero depending where the sender was placed. But if the engine is pizzing oil under pressure out I don’t believe any system could warn you soon enough.Don't some engine monitors already do that?
Guy in Kiplanes did the same thing in the '80s with a A65. Don't recall the actual time, but was about 10-20 minutes until the engine started to labor.Still, the Flightchops guy did a video a while back where he drained all the oil out of an engine and ran it at cruise power until it seized. It lasted a surprisingly long titime.
I gather they want a gauge that activates before the BANG! but after the HISS.If the oil departs the engine that rapidly, it will be via a sizable hole in the engine and I suspect the BANG! of one or more pistons making their exit will be a sufficient annunciator.
the punch line is that the software guys say "wait, before we get ahead of ourselves, we need to push the car to the top of the hill, close and reopen the windows, and see if this happens again."
