How the Christen inverted oil system system works on a Super Decathlon

Thanks for explaining. I've wanted to know this for a long time👍🏻😎

It's difficult to find videos from GA aircraft mechanics so thanks for this!

[@ZhihengCao]

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?

[@TTURBOVOLVO]

Thanks!

Is this different from Dry sump lubrication system?

[@kycsip3066]

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- kzbin.info/www/bejne/f2HPl5eLjdaJaMk
