Airbus\u2019 A330-900 <\/strong>flight-test aircraft \u2013 MSN1795 \/ F-WTTN \u2013 recently flew to Toluca in Mexico, and then to La Paz in Bolivia. There it conducted a fortnight long \u2018Hot and High\u2019 flight test campaign to prove aircraft and engine performance in high-altitude, warm and humid airport environments.<\/p>\n\n\n\n

Toluca airport lies at an altitude of 9,186ft (2,800m), while La Paz airport is at 13,300ft (4,054m).<\/p>\n\n\n\n

This is not the first time that Bolivia is selected by Airbus to test its aircraft. The country\u2019s extreme hot climate and high altitude are ideal for testing the design limits of its aircraft under such operational conditions.<\/p>\n\n\n\n

Extending the A330neo\u2019s operation envelope<\/h2>\n\n\n\n

This is the first time that this particular aircraft \u2013 the A330neo \u2013 had operated from airports at such high altitude, and this is part of Airbus\u2019 incremental envelope extensions for the aircraft. This will be especially beneficial for airline customers whose networks require such operations.<\/p>\n\n\n\n

Overall, the main objective of this certification exercise is to expand and certify the wide range of airports from where the A330neo can operate. Up to now, the A330neo has been certified to operate at airports that are up to 8,000ft elevation. However, following certification approval, which is expected in Q1 2025, the aircraft will be able to serve airports that are up to 12,500ft in elevation. Such locations include: China and Tibet (eg. Lhasa); Central and South America (eg. Bogota, Toluca, Quito and Mexico) and in Africa (eg. Addis Ababa).<\/p>\n\n\n\n

Wide range of tests<\/h2>\n\n\n\n

While the primary focus of the tests conducted is to evaluate take-off and landing performance \u2013 especially since the increased altitude reduces engine thrust levels, the aircraft also conducted local flights to evaluate climb and approach performance. Other tests included multiple engine starts, system behaviour verification, low-speed taxi and rejected take-offs. In the case of the engine starts \u2013 a crucial part of the campaign \u2013 the tests included special instrumentation to measure the starter air pressure, which would be affected by the high airport altitude.<\/p>\n\n\n\n

During the campaign \u2013 which took place between 18th and 30th March \u2013 a team comprising around 40 Airbus experts participated in the planning, logistics, maintenance, local liaison (airports, ATC, authorisations, permits etc), tests-support, execution, analysis activities \u2013 and flying of course. The early test results already reflect the good performance and behaviour of both the aircraft and its Trent 7000 engines.<\/p>\n\n\n\n

Capt. Franck Busnel, the mission leader as well as being one of the test pilots, sums-up the campaign: \u201cBy 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 \u2013 and with the advantage that the A330neo is much more fuel efficient.\u201d<\/p>\n\n\n\n
