In a recent flight-test campaign, Airbus’ A330-900, designated MSN1795 / F-WTTN, took to the skies above Toluca, Mexico, and La Paz, Bolivia to demonstrate its performance capabilities under challenging high-altitude conditions. Over a two-week period, the aircraft was subjected to rigorous testing in warm, humid, and elevated airport environments.
The tests were held at Toluca Airport, situated at an altitude of 9,186 feet (2,800 meters), and La Paz Airport, located at 13,300 feet (4,054 meters). This marks a significant milestone for the A330neo, which had not previously operated from such high-altitude airports.
Extending Operational Capabilities
This campaign is part of Airbus’ strategy to gradually expand the operational envelope of the A330neo. With a current certification up to 8,000 feet, the aircraft is poised for an upgrade. Upon receiving certification approval, anticipated in the first quarter of 2025, the A330neo will be equipped to operate from airports at elevations up to 12,500 feet. This adjustment will cater to a broader range of global destinations, including challenging locations in China, Tibet, Central and South America, and Africa.
Comprehensive Testing Regimen
The focus of the testing extended beyond basic performance assessments to include a series of specific evaluations such as take-off and landing efficiency, engine thrust levels at altitude, climb and approach metrics, and multiple engine starts under varied conditions. The campaign also scrutinized system behavior, conducted low-speed taxi tests, and executed rejected take-offs.
Expert Team On-Site
Approximately 40 Airbus specialists were involved in the campaign from March 18th to March 30th, handling planning, logistics, maintenance, and coordination with local authorities. Their efforts culminated in positive early results, showcasing the effective performance of both the aircraft and its Trent 7000 engines.
Capt. Franck Busnel, the mission leader and one of the test pilots, emphasized the significance of the tests: “By extending the envelope of operation of the A330neo, which was successful, we can show to the operators, the current one or the new ones, that the aircraft reaches the same capability of the A330ceo in term of high-altitude operations – and with the advantage that the A330neo is much more fuel efficient.”
These tests not only demonstrate the aircraft’s robust capabilities under extreme conditions but also align with Airbus’ commitment to enhancing the operational flexibility and environmental efficiency of its fleet.
