Tamarack Aerospace is in the final stages of FAA certification for the first commercially viable installation of its Active Technology Load Alleviation System (ATLAS), which allows wingtip extensions with winglets to be installed without increasing the load on the wing. The installation includes Tamarack Active Camber Surfaces (TACS) on the outboard portions of the trailing edges of the wings. The TACS automatically activate when additional load is put on the wing, such as during turbulence or maneuvers that increase G-load. The first STC for the system will go to the Cessna Citation 525 series: the CJ, CJ1, CJ1+ and M2. The system is already certified in Europe and is available for installation there.
We Fly: Tamarack’s Active Winglets
Key Takeaways:
- Tamarack Aerospace is nearing FAA certification for its Active Technology Load Alleviation System (ATLAS) for Cessna Citation 525 series aircraft, allowing wingtip extensions and winglets to be installed without increasing wing load.
- The ATLAS system dramatically improves climb rates (e.g., reaching FL 410 in 34 minutes) and reduces fuel burn by 15 to 25 percent.
- Further benefits include increased payload capabilities, extended airframe service life due to reduced stress, and enhanced lateral stability at high altitudes.
