Good evening,
Interesting....
Ok so the center of gravity is the point at which the entire weight of the plane may be considered as concentrated so that if supported at this point the plane would remain in equilibrium in any position.
1) So does this point keep changing during the flight? Where is that point generally located?
Ok, so let me take all the computers on your picture:
FMGEC = Flight management, guidance and envelope computer
FCMC = Fuel Control and Monitoring Computer
FWC = Flight warning computer
FCPC = Flight Control Primary computer
2) Ok, as I don't know all of these computers, I just would like to compare with the A320:
a) I have heard about the FMGS/FMGC about the A320, but never about the FMGEC. Has the A320 a FE?? If not, who controls GW and C.G?
b) Can we say that FCMC = FQI + FLSCU?
c) Does an A320 have a FWC? So each time a computer detects a problem, it sends it to the FWC (and the FMGEC maybe, no?)
d) FCPC...hmm... can we say that FCPC is kind of ELAC on Airbus? ELAC + SEC? ELAC + FAC? FAC + SEC?
3) Ok, so the FCMC is controlling the gross weight and the center of gravity. But is it calculating the fuel's GW? Is it calculating the plane's C.G?
4) So you have a AFT CG Monitor inside the FE.
The FWD CG is calculated by getting the CG calculated by FCMC?
CG calculated by FCMC - AFT CG calculated by FE = FWD CG?
It's all for now! Thanks a lot A33Zab, BuzzBox, FCeng84, titaniumwings, Uplinker, vilas and everyone else!
