Brad be cafeful what you study as far as additional info with regard to the airplane. Some things are not standard across every operator.. for example the gear limitation from bombardier is 250 but PSA uses 220 to keep things as common between the 200 and 700 as possible... also some operators allow the use of the autopilot to 80 ft per bombardier but PSA restricts it to 100 ft on an ILS... not big differences granted...but don't memorize numbers that might change... If you want to get a little ahead get the cockpit posters and the buttons book...that seemed to help a lot of people..though honestly I didn't think systems was that hard...
