Question, is it normal for the oil pressure to drop to yellow arc when flying inverted? For how many seconds should one expect the oil pressure to be yellow if it is a transient thing?
It is different. This is a wet sump as the oil is still contained in the oil pan and then pumped through the engine. But in its inverted mode it is somewhat like a dry sump as the oil has to be fed to the oil pump. Check out engineering explained’s video on the topic- th-cam.com/video/I0lfdUXqV2g/w-d-xo.html
It's difficult to find videos from GA aircraft mechanics so thanks for this!

Is this different from Dry sump lubrication system?
