Bombardier Commercial Aircraft announced today that its CRJ700 and CRJ900 Aircraft are now certified to operate at a higher temperature. The CRJ Series obtained a new International Standard Atmosphere certification (ISA + 40 degrees Celsius) from Transport Canada (TC) and the Federal Aviation Agency (FAA) in May 2018.

The certification process required studying the effect on engines, auxiliary power unit, environmental control system, Firex system, avionics, landing gears, flight control, hydraulics and electrical systems and aircraft performance.
The ISA+40°C certification upgrade on the CRJ aircraft is available as an optional feature, both for new production and retrofit. American Airlines is the first operator to take advantage of this upgrade.
