Boeing's aren't that tough if you get automation confusion. You can hand fly it very easily and very quickly. If you desire to get back onto automation it is also easily accomplished no matter how screwed up the level of automation(FMA displays) is -
click, click = A/P OFF, A/T's OFF.
FD's - both OFF
FD's - both ON
You're in basic automation level. If you can't figure THIS situation out you have no business being in the cockpit -
Select roll and pitch mode as desired. Since you've been screwed up maybe
HDG - select
and
V/S - 1000' would be simplest.
A/T's - Speed
Obviously verifying the FMA's to see that the automation is actually delivering the desired thrust/roll/pitch mode.
