IMO Best plane around, complicated sometimes, but a lot more challenging and fun than an RJ, nothing on everyone that flies the jet but you'll work a lot harder flying this ol' pig than a jet.

I'm just finishing up Piedmont's training, start the IOE/SOE portion tomorrow. I dunno if you're on the 100/200/300/400. The 100 is probably the most complicated the 200/300 are pretty much the same plane with a bigger engine and the 400 is basically an RJ.

The hydraulic systems, 3000PSI normal 9 gallon/minute, two standby pumps at 2925PSI and 1.5 gal/min, are pretty straight forward as well as the electrical. Start reading about 115 Volt fixed and variable frequency AC power as well as your standard 28 volt dc systems.

"Dundem" is pretty much spot on. Your best friend would be someone thats in a class in front of you at your airline, chances are they'll have a good idea of whatever written tests cover.

Long story short, you might try and hunt down some material. i know british airways has some stuff out there.
