Hi again;If I remember correctly, a while back there use to be a stand alone FMC unit put out, I think, by PMDG so that one can check out this advance feature and practice entries. If I am incorrect in this recollection, forgive me. On the other hand, if there is anyone out there that knows of a place where I can download this practice FMC, would you give a web location, that is, of course if the stand alone FMC/CDU exist. Note: I would love to practice on my work computer--ONLY DURING MY LUNCH HOUR, OK.

Dear Mr OK.You need to sign your name or you'll be in trouble.try the Project Magenta website - you can download both a Boeing and an Airbus FMC to fiddle with.

AS I recall the old Dream-fleet B737-400 had an FMC that you could load up independantly of FS allowing you to twiddle with it to your hearts content! Hope that helpsKris

Might not be exactly what you are looking for but I think it is worth a look. http://www.meriweather.com/747/ped/cdu.htmlWhile you are there look at the other pages.
