Recently had this come up. As per the approved MEL on fleet, the left engine bleed was inop. The O item specifies that with the LEFT bleed inop; Operations (O) 3.B.2: Operate the left pack using the right engine bleed, the right
pack OFF and isolation valve OPEN.
My question is, why run the left pack across the iso valve thru the manifold from the right engine bleed, instead of running the right pack from the right bleed valve with the iso valve closed? What am I missing in the system here? :ugh:
