ProLine Fusion Upgrade By Constant Aviation Certified By Transport Canada A major development for Constant Aviation with regards to their efforts to upgrade Bombardier Challenger 604 flight decks has come through thanks to certification by Transport Canada. Constant Aviation has done these upgrades to Challenger 604s already but in the United States to N-registered aircraft. The new STC validation now gives them more scope to include Canadian-registered 604s. "Transport Canada validation opens up an important market for the Challenger 604 Pro Line Fusion upgrade," said David Davies, Constant Aviation CEO. "There are more than 20 Challenger 604 aircraft registered in Canada, and their operators now have access to an unmatched avionics solution that modernizes these aircraft for many more years of use. Based on the response we have seen since launching this program in the United States, we expect Canadian-based operators will move quickly to install the Pro Line Fusion package on their Challenger 604 aircraft."
