Hello,
From my many, many hours spent in the 1-11 200 on my recent project planning, I've found that although there isn't an autothrottle system, it's nice and easy to control the speed to give you what you want.
Maintain 94% in the climb, (you'll need to keep advancing the throttles as you gain height) and then just set the cruise speed when you level off, it's not that fiddley to get set.
On descent, I find that descending at idle and 2000fpm holds about 280kts, and when you get to FL130, reduce the rate of descent to 1500fpm, maintain idle and you'll slow to 250 in time for FL100.
The only bit that takes a lot of getting used to is the amount of power needed to maintain approach speed with everything down; so give it plenty and you'll be fine.
Hope this helps,
Paul C
