Boeing’s third test 787 has entered a two-week phase of extreme weather tests at McKinley Climatic Laboratory at Eglin Air Force Base, Florida, as part of the aircraft’s type certification effort.
The company has posted a very cool (sorry about that - couldn't resist) video of the tests on its website which takes you inside the facility, and inside the aircraft itself.
The testing will expose the aircraft to heat as high as 115 degrees Fahrenheit (46 Celsius) and as low as minus 45 degrees Fahrenheit (minus 43 Celsius). Boeing says once the aircraft, ZA003, is stabilized at either the hot or cold temperatures, flight test technicians will follow the 787 maintenance manual to prepare it for flight release and operate under these conditions. “Sensors and monitors will allow the test team to determine if all systems hardware and software operate as expected,” adds the manufacturer.
Cold-weather testing is being conducted first, with preliminary hot-weather testing to follow. Additional extreme-weather testing will be conducted later in the flight test program, says Boeing.
