Airbus insists it is not changing the door configuration on the A350-1000 despite the prominent display of a model featuring a fifth pair of exits during a global technical briefing.
The additional exits, a pair of smaller doors between the two pairs of main doors aft of the wing, had appeared on a rendition of the Cathay Pacific A350-1000 when the carrier ordered the type during the Farnborough air show last year.
Airbus subsequently claimed that the illustration - which featured in a video of the aircraft in Cathay's livery - had been erroneous.
But the extra doors also featured on a large model of the A350-1000 positioned on the stage during a broad Airbus briefing on 5 June - a model which had been updated to include the characteristic black cockpit window frames on the type.
A350 programme chief Didier Evrard tells Flightglobal that the doors were considered as an option for customers wanting higher-density seating arrangements with a 10-abreast cabin.
But he says that Airbus has since backed away from the concept. "The A350-1000 will only have four [pairs of] doors," he says, stressing that these will be sufficient for evacuation.
While Airbus had toyed with the extra exits, Evrard insists their continued inclusion in publicity material is a "mistake".
The 370-seat Boeing 777-300ER, against which Airbus is pitching the 350-seat A350-1000, is fitted with five pairs of doors.
Airbus's illustrations of the -1000 have typically shown the aircraft with four pairs of exits, two forward and two aft of the wing.
