Squibb....it was an honest question and thank you for your response.
What I get from your answer is there is no way to know with certainty there has been a complete/near complete loss of oil and the only suggestion would be a decrease or loss of pressure which could also be due to other causes or even bogus indications.
Is that a correct assumption?
Way back during this thread I also suggested temperature sensing also relied upon having oil to accurately reflect the actual oil temperature and upon a loss of oil it would be possible to lose reliable temp indications.
As I see it....without knowing there has been a loss of oil, one would not know when to start the 30 minute countdown timer.
Am I missing something in looking at the way the oil quantity can be ascertained in flight by the pilots?
I used to have a valid 92 Checklist but lost it in a hard drive death so I cannot look back on that to refresh my recollection.
