A/C general exam (oil by-pass question??)
Hi
Been working through the confuser again for my A/C general exam and come across a question which I'm not 100% sure about. The question is: "The valve which allows oil to either flow through or bye-pass a serviceable engine oil cooler is":
A - pressure activated
B - manually activated
C - pneumatically activated
D - temperature activated
I intially thought it was A (pressure activated) but apparently it is D (temperature activated)? I also seem to remember reading somewhere about this very same answer in the PPL confuser being wrong? Would appreciate your views on this as I have an impending exam!
Thanks!
