Few things up front, got to have HF radios (dual?) and two FMCs. Also have to have two cross feed valves. For the most part its just adding extra redundancy.Kev3188 said:Ok cool, and thank you.
No structural or performance differences at all (besides the differing cabin layout/capacity)?
Then after that it is mostly extra checks that have to be done. Cold start of the APU, can only have so many IFS per year and only so much oil consumption and stuff like that.
as Mechanics we have to be ETOPS certified to work on those aircraft also.
