Active Winglets extends CJ3 range by more than 250nm
(Sandpoint, Idaho, May 20th 2017) - Tamarack® Aerospace Group, Inc. completed a one-stop Paris, Texas (KPRX) to Paris, France (LFPB) flight in the company’s Active Winglet equipped Cessna Citation CJ3. The aircraft (N52ET) is currently undergoing flight testing in order to achieve FAA and EASA Supplemental Type Certification for the Active Winglets on the CJ3. Certification is expected in the last quarter of this year.
Carrying two pilots, one passenger and loaded to max take-off weight, the jet departed Paris, Texas flying 2,104 nautical miles to St. John’s, Newfoundland (CYYT). The flight had a 4 knot tailwind and flew at 376 knots true airspeed for 5 hours and 32 minutes. The total fuel burn for the first leg equaled 3960 pounds (107 gallons per hour block fuel burn). The St. John’s, to Paris–Le Bourget Airport (LFPB) flight, a distance of 2244 nautical miles, took 5 hours and 45 minutes flying at 373 knots true airspeed with a 17 knot tailwind. The total fuel burn for the trans-Atlantic leg was 4210lb (108 gallons per hour block fuel burn).
These flights would not have been possible in a CJ3 without the significant performance improvements delivered by the Tamarack Active Winglet system. Tamarack’s unique Active Winglet system is comprised of a wing extension with a load alleviation device, and a highly-tuned winglet. The load alleviation system actively reduces loads during gusts and maneuvering, negating the need for wing reinforcement. This combination of elements amplifies the aerodynamic efficiency of the modification, significantly improving the performance of the CJ3. Extensive company flight testing has shown that fuel burn at maximum Mach number at Flight Level 450 has typically dropped from around 800lb/hr to 700lb/hr. Combined with a faster time to climb and much quicker acceleration when leveling at cruise altitude, the fuel savings significantly extend the range of the CJ3.
The jet was flown by owner, shareholder and business man Gary Heavin who had this to say; “I’ve flown my CJ3 from Texas to Europe many times but have always need to stop two or three times to refuel. The performance of the aircraft was fantastic throughout the trip. With a full load, the aircraft climbed directly to FL450 in 25 minutes, accelerated to cruise Mach in less than 5 minutes and cruise fuel burn was about 100 pounds per hour lower. The ride in turbulence was noticeably smoother, too. The addition of Active Winglets truly puts the CJ3 in a category all its own.”
Tamarack founder and CEO Nick Guida flying right seat noted: “Climbing out of St John, I was particularly pleased with the climb performance enabled by the Tamarack Active Winglets. As anyone who has flown the North Atlantic knows, the atmospheric conditions are often very warm (ISA plus) making many aircraft struggle to climb to the desired cruising altitude. Step climbs are typically required and can be a challenge to coordinate. We encountered up to ISA +12 on the climb yet were at altitude in 25 minutes. When Gander Control asked if we could make Flight Level 450 before the entry point of our high altitude track, it was great to answer emphatically, “Yes!” Active Winglets makes the CJ3 stand out in the market and demonstrates the ability of our Active Winglets to transform the performance of almost any aircraft type in a cost effective, straight forward retrofit. This CJ3 trans-Atlantic flight builds upon our previous record breaking flight of our Active Winglet equipped CJ where we flew a distance of 1853nm.”

Active Winglets are FAA and EASA certified on the Cessna Citation CJ, CJ1, CJ1+ & M2. Certification of the CJ3 is expected by the end of 2017.
