hi guysA big factor of why I love PMDG a/c is the fully working FMC (hey I like my procedures ok? :)). anyway, would it be possible for say PMDG to sell (as a separate download) a customized or generic FMC to work with other payware a/c that don't have it? eg. the captsim B707 (yes its old, but every time I watch a 707 cockpit vid...there's always a shiny FMC there), CLS B747 classics, etc?? or is it too 'linked in' to the actual product? I know another software company sells panels .... maybe just a thought.*edit* corrected spelling - doh!

Since a huge portion of the FMCs functionality involves fuel planning, altitude planning etc, it would have to be build from the ground up for a specific aircraft. Otherwise all it is is a GPS.

hmmm...thats a bugger.

Is there not a free fmc called vasFMC, never used it myself but I heard it was pretty good.

Have a look at Ernie Alsoton's ISG1 package, it comes with 3 types a Smiths, GNSXLS and an MCU (which I am not familiar with).Here is some info for the Smiths unit:Smiths style FMSFlight Management system based on the look nd feel of the Smiths FMS system used in Boeing aircraft.· Create new flight plans· Direct To a Navaid/Fix· Load Stored Flight Plans· Load FP's created by FS9 or FSX planner· Save created Flight Plans· Create user defined waypoinmts· Create Offset waypoints (via wpt/radial/dist)· Define and execute multiple (up to 5) holding patterns· Insert Sid/Star into flight plan· Insert Airway segment into flight plan· Progress page /w fuel predictions· VNAV waypoint speed, and altitude restrictions· Define reference Navdata points· Define climb and descent speed restrictionshttp://secure.simmarket.com/ernie-alston-integrated-simavionics-group-1-(isg1).phtml

As Noah said, performance libraries are the biggest problem - you can't just drop an FMC into an aircraft and have it be able to properly predict fuel burn, climb/descent performance, actual VNAV path calculation etc - that all requires knowlege of the aircraft's performance envelope, which we specifically build into each FMC we've done in our products...
