Airbus Begins A350-1000ULR Flight Testing to Support Qantas 'Project Sunrise' Ultra-Long-Haul Routes

Airbus has officially launched a flight test program for the A350-1000ULR (Ultra Long Range) variant, conducting systematic validation of the critical technologies required for Qantas' 'Project Sunrise' non-stop ultra-long-haul operations.

Three Core Technology Areas Under Evaluation

The flight test campaign covers the following key areas:

• New Fuel Systems: Optimization and validation of fuel storage and management systems designed for extreme-range operations
• Cooling Technology: Assessment of onboard thermal management capabilities under sustained long-duration flight conditions
• Airworthiness Certification: Ensuring all modifications comply with airworthiness standards set by civil aviation authorities across relevant jurisdictions

Background: Qantas 'Project Sunrise'

'Project Sunrise' is Qantas' ambitious ultra-long-haul route program, aiming to operate non-stop commercial flights from Sydney to cities including London and New York. The routes span approximately 17,000 to 20,000 kilometres, with projected flight times of 19 to 22 hours — which would set new records for the longest non-stop commercial flights in aviation history.

Technical Challenges of the A350-1000ULR

The A350-1000ULR is a specially modified derivative of the existing A350-1000, enhanced for ultra-long-range missions through increased fuel capacity and optimized flight systems. The current flight test campaign represents an essential milestone before the aircraft can enter commercial service.

Airbus is steadily progressing through the various test phases, and the pace of certification will directly determine the commercial launch timeline for Qantas' 'Project Sunrise'.
