The Additional Center Tanks (ACT) provide airlines with the opportunity to increase their aircraft total fuel capacity. It gives additional operational flexibility. An airline can extend the aircraft range at both average and low payload conditions or they can increase their aircraft payload significantly at fuel-limiting ranges.
To enable airlines to efficiently use the MTOW capabilities of the aircraft, the A320 family aircraft have options to install additional fuel storage installed in the aft cargo hold.
The options are split into four packages:
- Full provisions for installation of one Additional Center Tank (ACT) in the aft cargo hold.
- Full provisions for installation of two Additional Center Tanks (ACTs) in the aft cargo hold.
- Installation of one Additional Center Tank (ACT) in the aft cargo hold.
- Installation of two Additional Center Tanks (ACTs) in the aft cargo hold
The ACT is constructed as a light alloy external shell with an internal flexible bladder holding the fuel.
The ACT solution is available on A319, A320 and A321. With the provision already installed on the aircraft, an ACT can be fitted over one eight hour shift. The ACTs can also be removed and the aircraft configuration restored to normal over an eight hour shift. The ACT provisions remain in the aircraft.
