Fuel #'s may be great, but from a pilots standpoint, we have complaints. VNAV is a mess. It cannot hold the PATH with out speed brakes on every single descent. (Think if we get the -8i for PAX...
Hand mic placement was an afterthought. No place to put flight plan, jepps, docs, etc.
Hand flying is no pleasure, it hunts and fishes in pitch.
Until this thing gets tweeked, I'll take the -400 any day.
