The Flight Operations Versatile Environment (FOVE) is a separate software system used with Airbus aircraft by dispatchers to determine performance data to enter into the FMS. There seems to be little info on the interwebs about it.
Since the FMS takes the parameters and makes its own calculations, I'm not sure why a separate system is needed. A U.K. CAA bulletin says:
"As [FOVE] gives more accurate performance figures it is generally used on occasions where takeoff performance is more limiting."
In what way does it produce more accurate figures than the aircraft's own FMS? Is FOVE created by Airbus or a third party? If it's third party, has Airbus approved it?
How does FOVE work with the FMS? Do they just override the FMS calculations, or does it give them alternate data to enter into the FMS to create the required parameters?
