Ok, guys, now that we're off topic I'd like to report that, after using my Civa planes for numerous flights, I jumped in one of the FMC driven ones again, just to catch the difference.
Wow, that was like replacing a Windows PC with a NES. Just put in the cartridge and start the game.

Speed bug settings? FMC driven. Tuning the right VORs for flying the Departure procedure? FMC driven. Following altitude constraints by doing some maths? FMC driven. Updating your nav sources to stay accurate? You name it.
Coming from the steam gauged 727/707 things and entering a modern plane means that you enable power and press "go!".  ;D
What a difference! Boring, but relaxing on the first try (after some time of absence), I must admit.  :P
