Lots of good (and some really bad) info for you
bunk22 in this thread. And congrats on choosing AWAC as I think you'll have a good time over there. It's a damn shame my company didn't get off their ass and get you in a class.
First off, I'm not sure how much experience you have with glass, but if you don't, the two things that will make the transition easier for you are the sky pointer (it sits at the very top of the ADI display and ALWAYS points straight up) and the speed trend vector (it's the little pink worm that shows where your speed will be in 3 or 5 seconds depending on the software). If you just try to "squish the worm" by using thrust lever input, you'll have a pretty easy job of staying on speed, even if you don't know the pitch/power settings of the plane.
Moving on beyond that, another big change will be switching from a training/fighter/only guy in the plane mindset to a SMOOTH control input mindset. I've seen SO many new hires who only were students, instructors and then survey/freight/whatever pilots not have the concept that you have to be VERY gently with the plane with people in the back. I have a funny (over beers some time sort of) story about the first time I flew a charter in a Seneca with passengers in the back.
As far as what has been discussed in this thread so far...
The gear is very forgiving, but if you aren't tracking straight when you touch down it can be a pretty violent landing. Learn to kick the rudder early and often on touch down.
The plane lands VERY nose low. It's not unusual for a FedEx guy (who's never ridden up front on a 200 before) to let out a girlish scream during the flare due to the sight picture of pretty much plowing the nose into the ground. The plane *almost* lands three pointed. I pull 1/3 the power at 100 feet and the rest at 50, "flare" at about 10 feet to 1 degree up and leave it there and let the plane settle to the ground. It's almost impossible to have a GREAT landing in the 200 (unlike the 700/900) but it's rare to have a REALLY bad landing (again, unlike the 700/900).
The flaps had lots of issues. Most airlines have reduced their flap extension speeds from 230 down to 200 (for 8 and 20 degrees of flaps) and over here at least, our flap fail numbers have gone down by about 80%. They still do break (especially when you get frozen water in the system) but it's not as bad as people make it out to be. I've done about 5 flapless landings in 6000 hours in the jet. One side benefit of landing flapless is that due to the high speed (it can be above 170 knots) you come in nose high and it feels like you are flying a real plane.
The engines are weak. Airspeed management is the name of the game. Even at ISA+10 it is possible to get a fully loaded 200 up to 34,000 feet. It just takes a while and you don't move forward very much while you do it. That said, a light airplane in the winter will have no problem holding at least 800fpm all the way up. Just be aware of getting on the back side of the power curve and that there are times when the altitude you are filed for is not one that you can actually fly at.
A related thing to this is that the thrust levers don't sync in any way. If you don't watch the N1 gauges you will constantly be out of sync. Depending on what type of headset you use (side suggestion: Spend the money on a Telex 850 or other noise canceling model... the 750s are cheap and do work, but you will get some really loud planes and the fans inside can be pretty loud too. lots of guys use DCs, but personally I get a headache after 5 minutes with those), you may not be able to hear it, but everybody else will. Do everybody a favor and sync up the damn N1s..
Anti Ice (wings especially) will kill your climb performance. Just how it is. Descending in icing conditions requires the thrust levers up a bit to keep enough air coming off the engines. It is considered normal practice to descend in icing with the spoilers out a bit and the thrust up. Silly (especially for a Canadian airplane) but just another thing to do. Also, the spoilers are mostly noise makers in this plane. They do some speed reduction, but not much. If you really need to come down, get the gear out and the flaps to at least 20 or even better 30.
Learn the FMS inside and out when you can. Despite the lack of automation attached to it, there is a ton of useful information embedded in there. Also, the radar is a bit of a black box. You will figure it out as you go.
You will start to get a handle on the tricks of operating the 200 as you go. Things like having to pull the power back slightly when transferring the bleeds when single pack. Things like ignoring an EFIS COMP MON message when departing LGA (or pulling in to any jetway). Things like not asking "what the hell George doing now" and just clicking off the autopilot and hand flying for a bit.
Despite all its flaws, it's a pretty damn good airplane. I hope you enjoy flying it.
