This is the reason why the wing tanks are the first tanks to be filled and the last ones to be emptied and this no matter the aircraft type. Moreover, as the wing tanks are generally divided into outer and inner wing tanks (except on
A321), the outer tank is filled first in order to bring the mfuelg vector further out. However, it is worth pointing out that this rule is only applicable to a certain extent : too much weight in the outer tanks creates some structural strain on the wings on ground (ie when not balanced by the lift).
On top of this general considerations, each aircraft family (ie. A318/A319/A320/A321, A330/A340 and A300-600/A310) has its own characteristics. That is why this part presents the following aspects for each aircraft family separately:
. Fuel tanks: location and capacities
. Fuel systems: engine feed system, control and indication
. CG travel during refueling: refueling sequence and resulting fuel vector
. In-flight CG travel: defueling sequence, in-flight fuel transfers
. CG control system (when applicable)

2. THE SINGLE-AISLE FAMILY
(A318/A319/A320/A321)
2.1. Tanks and capacities
Compared with A318/A319/A320, A321 wings have been modified in order to support higher weights. As a consequence, contrary to all the other Airbus aircraft, there is no separation between outer and inner tanks on A321.

2.1.2. A319 Corporate Jet
The A319 CJ can be fitted with up to six additional center tanks. Due to specific issues raised by this configuration, applicable information will be presented separately from other A319 aircraft.
