Our friends at simFlight.nl catched an helpful website to use for free and online interactive check-lists of many aircraft of many kinds (airliners, single or twin engine, propeller, military..). OK it’s not an exhaustive aviation catalog but it’s very practical if you have a second monitor or network computer to display, check the items one after the other. Visit checkplane.com.
Another solution can be within your simulator (FSX / FS2004) if you have one monitor setup. FSPS sells Ultimate Check-lists with a check-lists editor to support more aircraft of your choice if they are not in the original data base.
