Europe's air transport safety regulator has certified a higher-weight version of the Airbus A350-1000.
The -1000 secured certification at its basic 308t maximum take-off weight on 21 November.
But the European Aviation Safety Agency has since updated the certification document to include a 311t version of the Rolls-Royce Trent XWB-powered twinjet.
The higher-performance aircraft, weight variant 001, has a maximum landing weight of 236t and maximum zero-fuel weight of 223t.
Airbus had disclosed last year that it was offering a 311t version of the A350-1000, but its own documentation on the aircraft had also briefly hinted at a possible 316t version.
Qatar Airways is due to take delivery of the first A350-1000 but the handover, originally intended before the end of last year, has been postponed.
