Maiden Flight: The Airbus A350-1000ULR Takes Wing

Toulouse, France — June 2, 2026

Airbus has officially launched the flight testing phase for the MSN 707, the inaugural aircraft of a 12-plane order placed by Qantas. This specific model, the A350-1000ULR, represents a leap in aviation endurance.

✈️ Flight Mission Overview

The first flight lasted exactly 3 hours and 43 minutes, with the aircraft climbing to an altitude slightly exceeding 41,000 ft41,000\text{ ft}41,000 ft. The mission was executed by a specialized Airbus Flight Test team to validate the airframe's performance.

"The A350-1000ULR is designed to conquer the final frontiers of non-stop travel, bridging the gap between Australia and the world's major hubs."

Technical Enhancements

The primary catalyst for this aircraft's extreme endurance is the integration of a Rear Center Tank (RCT).

  • Fuel Capacity Increase: ≈20,000 liters\approx 20,000\text{ liters}≈20,000 liters
  • Range Extension: +1,000 nautical miles (NM)+1,000\text{ nautical miles (NM)}+1,000 nautical miles (NM)
  • Target Distance: ≈10,000 NM\approx 10,000\text{ NM}≈10,000 NM
  • Max Flight Duration: ≈22 hours\approx 22\text{ hours}≈22 hours

🛠️ Certification & Testing Roadmap

The MSN 707 is currently entering a two-month flight test campaign. The goals are not limited to fuel; the crew is also certifying a new galley air cooling system featuring lighter and more efficient refrigeration units.

Certification Checklist:

  • General aircraft performance checks
  • New fuel system architecture validation
  • Galley air cooling system certification
  • Cabin ventilation and temperature control testing

Once these tests are finalized, the aircraft will be retrofitted to meet the specific commercial requirements of Qantas.
