I asked the same question 3 weeks ago , I wanted to learn how to use a FMC or get a better idea.
PSS 1.3 costs around 300$ and you need 40 G hard drive (not for a laptop),instead I found a software for around 50$which is an additional software for FS2002.(planes sold with the fs2002 pro really suck)
after 4 days, woooow, I learned so much that if I have been in a school to learn what I know now, it would have cost me a fortune.
Now I know how to use the FMS, flight plan, index cost, entrypoint, TOD,TOC, speed restriction, CAT1/2 app,fuel managment..., SID/STAR through the FMS, open climb, eco descent, flight cruise,APU...
it s not like a real plane, but when I "was" in the cockpit, this software showed me what a big airliner is.this software is really good.it worths my 50$.
if you wish to know the name of this software, please write me.
