I've got "FSX" Gold Acceleration edition, I've got some Decent Boeings and Airbuses & Lockheed Commercial passenger aircraft / Jetliners.  I'd like to know, what is the difference between "FMC"  and "FMA" or are they the same things ??? I found on this web site (Simivation), a FREEWARE program called "FMA", so I downloaded it, and followed the instructions exactly, and Edited the Panel CFG file according to the instructions and put the FMA File in the aircrafts Panel folder as instructed.  Has anybody on here ever used this program  ------} ( http://simviation.com/1/search?submit=1&keywords=fma&x=0&y=0), will it work with default FSX Aircraft like it says ?? I'm going thru YOU TUBE Videos watching tutorials on FMA & FMC setting up and how to use.  Was curious if any of you out here have ever used that Freeware FMA Program thats on here and does it really work as it claims ??  Thanks , Jetranger  ( http://simviation.com/1/search?submit=1&keywords=fma&x=0&y=0  also see this ( http://www.youtube.com/watch?v=DSM60rwr-Ac&feature=related)
