The Falcon 6X has completed cold weather
testing, passing another major milestone towards certification,
expected later this year.
The test team of engineers consisting of
technicians and pilots from Dassault Aviation and engine
manufacturer Pratt & Whitney Canada endured temperatures as low as
-37°C (-35°F) during the long trial runs in Iqaluit, a tundra town
in the far north of Canada.
During the arctic
ground test campaign, the aircraft was cold soaked for three
successive nights and subjected to different start sequences each
morning. Teams then powered up the aircraft and conducted engine
ground runs and high-speed taxi tests.

Ground tests were followed
by a test flight during which anti-icing systems and handling
qualities were checked and the stability of fuel and hydraulic
fluid temperatures verified while the aircraft remained in a
holding pattern flown at 10,000 feet.
The tests, which
were completed at the end February, followed an initial series of
cold weather tests in Iqaluit in December, when temperatures dipped as low as -25°C (-13°F).
“The Falcon 6X continues to impress us with its
performance and reliability as we move through the certification
process,” said Carlos Brana, Dassault Aviation’s Executive Vice
President of Civil Aircraft. “The aircraft operated flawlessly at
the extreme temperatures an aircraft can be subjected to in the
severest climate conditions. That includes engines, systems and
low-temperature maintainability requirements.”
The 6X endured a total of 50 hours
of Arctic cold tests and has now accumulated some 650 flight
hours, and completed over 220 flights.
