737 Max Solution, Please Explain
As Boeing always offered a triplex alpha sensor array why do they not simply make that the standard?
Why, given the opprobrium and distrust they've generated over the origingal system, have they decided on a duplex system that at first glance looks like a cheapskate half- measure to be followed by an artifcial third electronic comparator, but not yet.
What is the additional cost of a triplex system over the simplex one? Surely not a deal-breaker on a $60m aircraft? I'd haave thought the development work on the new solution would far outweigh simply reverting to triplex and wrapping the problem up.
Anyone able to explain the reality?
