Gums, I'm not a fan of FBW, but I concede that it has some advantages. If I learned to fly one, I might even like it. The problem here is that you can't do FBW in a half-assed fashion. One air data computer, or two...using one every other flight, isn't going to cut it. One AOA input at a time, not going to work, either. Boeing tried to sneak some FBW bits into a manual reversion airplane, with deadly results. We haven't even heard the beginnings of a discussion of FBW spoilers to assist with a delicate landing attitude, due to the lengthened nose strut...with one AOA input. No doubt, one COULD go whole hog on a FBW 737, but then it wouldn't be a 737. But I am seeing piecemeal fixes to a piecemealed FBW application...and I am not happy with it.
Salute!
