give me a 737 any day. The E-jet FMS is utter rubbish, altitude and time preditions are woeful to say the least. Overhead panel automation is very good.
The autothrottle is terrible, the 170 is a dog (very rarely get above Fl350)
The 190 is not too bad to fly but I hate the 170. The screens are small and cluttered (unlike the nice dispalys in the 737/777), the FMS still has so many bugs in it, far to many to list.
Some really good systems, pitch compensation for thrust/gear/spead brake/flap etc. 3 deg descent makes track shortening a breeze, speed brakes that actually work inflight., carbon brakes....mmmm carbon brakes.
Heading up display ...why?
Even though the 737 ng was out of date before it was even built, the over head panel is a disgrace and it does not fly anywhere near a nice as the classic, I still this it to be far better than the E-jet.
So many electrical issues. Power down reset a very common thing. It takes a lot more time to set up or turn around than the 737.
having said that 90% of the guys who fly it, love it.
