0 KIAS for Hyd systems 2 and 3 -- they are backed up by electrically-driven demand pumps
Sorry not so, electric demand pumps are optional, we have Air Driven demand pumps on 2 and 3 hyd. Some also have 1 & 4 electric aux pumps, but not all, if it's an option that you pay for then we don't take it!
As stated it's irrelivant anyway, just for info.
