Hello MD83FO
Here´s wht you find in the AI FCTM :
ERRONEOUS ZFWCG ENTERED
The CG computed by the FCMC is erroneous. This induces the following
consequences:
· Incorrect CG is displayed on ECAM SD and on MCDU FUEL PRED page
· CG regulation is affected but “EXCESS AFT CG” warning remains
reliable.
· Minor impact on FM predictions.
· Additionally, VLS and Vapp speeds on MCDU PERF APPR page are
impacted (A340-500/600 only).
· At take-off, the pitch trim setting might be erroneous. This is minor since
take-off has been certified in full forward CG with full aft trim and vice
versa.
· In flight, the PRIM operate with CG=30% which has minor consequence
on the aircraft handling
· AP/FD control laws are slightly affected
· VLS displayed on PFD is impacted (A340-500/600 only)
Vaprot, Vamax, Vsw are not affected since based on aerodynamic data.

ERRONEOUS ZFW ENTERED
GW and, to a lesser degree, CG computed by FCMC are erroneous. This induces
the following consequences:
· Incorrect GW and CG displayed on ECAM and on MCDU FUEL PRED
page
· CG regulation is slightly affected since the aft target CG depends on the
weight but “EXCESS AFT CG” warning remains reliable.
· The SRS mode guidance may be affected (If VLS > V2 inserted on
MCDU PERF TO page).
· FM predictions and speeds are affected
· The FG and PRIM control laws are slightly affected
· The characteristic speeds displayed on PFD are affected.
Vaprot, Vamax, Vsw are not affected since based on aerodynamic data.
