Airbus has set a second-quarter 2014 target date to raise A330 production to 11 per month.
But the airframer's parent, EADS, cautions that this increase will depend on avoiding political fall-out from Europe's controversial emission-trading scheme.
Airbus has previously indicated its intent to increase A330/340 production this level, but backed away when uncertainty began to overshadow the air transport market in 2008.
The airframer has since opted to terminate A340 production.
But during the disclosure of EADS's full-year results for 2011 in Paris, the parent company said that the A330 rate would be raised owing to "positive order momentum".
EADS says this will take effect from the second quarter of 2014 but adds, however, that this will occur "provided the emission-trading scheme issue does not harm aircraft orders".
Production rate increases for the Airbus A320 family are "well underway", it says, "despite the ramp-up challenges".
