Oil Pressure Behavior
in 912 / 914 Technical Questions
7 years ago
This question is for a 914 installation. I am attempting to put an oil pressure switch on the auxiliary fuel pump circuit so that in the event of a crash, the current to the auxiliary fuel pump will stop when the engine stops. I have been assuming that as soon as the propeller stops turning, the oil pressure will drop to zero. But now I seem to recall that I have read on this forum that simply turning the prop by hand is enough to see a pressure reading on the oil pressure gauge.
So my question is, when the engine stops turning, does the oil pressure immediately drop to zero throughout the system, or does it behave differently than that?
