The Williams FJ33-5A-12 is a medium-bypass turbofan capable of producing up to 1,900 pounds of takeoff thrust at its full rating, but will be de-rated for installation on Canada to just under 1,200 pounds.
The FJ33 was originally certified in 2004, with the FJ33-5A variant certified in 2016.
FJ33-5A-12 will allow the aircraft to exceed the performance goals established for the project, company officials said.
Canada will now have a max cruise speed range in excess of 1,470 nm, with NBAA 100-nm reserves, and will be able to climb direct to its maximum operating altitude of 43,000 feet, even on hot days, company officials report.
