An Airbus A350 being tested from +45°C to −40°C inside the McKinley Climatic Laboratory.
The aircraft was exposed to extreme temperatures and humidity while engineers checked its systems and cabin installations.
The engines were also operated during the tests, with the aircraft securely restrained.
Air conditioning, galleys, water and waste systems, and other aircraft systems were checked to verify they could operate after prolonged hot and cold exposure.
The controlled environment allows engineers to test conditions that would be difficult to reproduce consistently in normal flight testing.
The A350 spent about 2.5 weeks undergoing climatic testing.
A Cruz Sagrada seja a minha luz,
não seja o dragão o meu guia.
Retira-te, satanás! Nunca me
aconselhes coisas vãs.
É mal o que tu me ofereces.
Bebe tu mesmo os teus venenos!
