I downloaded Matthias Hoheisel's PMDG737 Operating Procedures and it includes a detailed check list, among other things. The first entry on the checklist is "Check Airplane Registration." Doh, in all the checklists I've seen that's the first time I've seen that. But it makes sense--be a bummer to fly off in the wrong airplane, lol.billg

Very funny Billg,However that is not the case, when you are told to "Check Airplane Registration" it is so you know what to say to ATC.Hope this clears that one up for you,Jason.I
