Fuel is jettisoned from the inner and centre tanks at about 1 ton per minute.
The jettison system:
- opens all crossfeed valves
- starts all main and standby fuel pumps
- starts an automatic forward transfer to the centre tank
Jettisoning stops when:
- stopped by the crew
- low level is sensed on one side
- combined inner tank quantity is < 10,000 kg
- the FCMS [Fuel Control and Monitoring System] stops at the level preset on the MCDU [Multipurpose Control and Display Unit]
