During a recent west coast tour of Tamarack’s Active Winglet equipped CJ, Pia Bergqvist, Flying magazine’s Executive Editor, joined Tamarack’s founder, Nick Guida, for a demo flight. Their flight began with a ground temperature of 28 degrees C. For a flight in those conditions, and a takeoff weight of 10,600lb, CPCalc (Cessna’s performance software) predicted it would take the jet 1 hour and 54 minutes to reach FL 410. The experimental CJ, with a brief hold at FL 230, got to FL 410 in 34 minutes. The 2 hour flight burned a total of just 1,200 pounds.
Writing in the December, 2016 issue of Flying, Pia said, “We had a chance to test out the (Active Winglet) system on the Citation CJ that has been used for the certification effort. The performance improvements are simply mind-blowing.”
Tamarack’s Active Winglet system for the CJ, CJ1, CJ1+ and M2 has been certified by the European Aviation Safety Agency, EASA. FAA validation of the system is expected at any moment.
