Ok so in fact the crossfeed manifold is not pressurized during takeoff in this scenario...
Thanks for the advice guys
; having been on glass before (albeit scarebus), I understand the importance of accepting it is an FMC/EICAS driven machine and that with a firm understanding of the "magic", all else will follow.
Having said that, I am still in a course-preparation phase, and was first going through the traditional systems to pick up similarities/ differences with the old lady before delving into Boeing's equivalent of FMS/ECAM!
So here's another system tech question... (but believe me when I start to study the FMC/FMA/EICAS I will have many more!)
If in flight with A/P R engaged I get an EICAS advisory >STAB TRIM 2, must I disengage the A/P (as you would have done on the 200)? By looking at the wiring diagrams, it would appear that in single-channel engagement A/P R can only utilize stab trim 2 (and similarly A/P L stab trim 3), but if this is the case why does our non-normal checklist not call for autopilot disengagement?
