Also...I wouldn't use autothrottles even if they were available on everything...because I'm eventually gunning for a couple of ACMI jobs on some old old freighters, and those things require a pretty good feel for how a turbine responds to power inputs...I can't imagine starting out a career in a E170, and never having to become fully in touch with the relationship between throttle inputs and engine response. I guess it's not that huge of a deal, but still, the plane navigates itself, the least you can do is get a feel for how to manage your thrust.
