Airbus's A350-900 prototype, MSN1, has overflown the Paris air show, during an attendance by French president Francois Hollande.
The aircraft made a single pass at about 13:25 along Le Bourget's runway 21 at a height of 600ft before executing a climbing right turn and heading south-west.
It had departed Toulouse at 10:50 to conduct a test flight in the southeast of France, flying over the Mediterranean coast and in the vicinity of Montpellier and Lyon.
The aircraft then turned north before descending towards Le Bourget, flying in from the east and turning to perform the pass.
Airbus had carried out the maiden flight of the A350 a week before and opened the aerodynamic envelope of the aircraft completely during a second test flight on 19 June.
