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, which uses Active Camber Surfaces (TACS) to allow wingtip extensions without increasing wing load.
- The ATLAS system dramatically improves performance, enabling significantly faster climbs (e.g., reaching FL 410 in 34 minutes compared to nearly two hours) and a 15-25% reduction in fuel burn.
- Additional benefits include increased payload capabilities, extended aircraft service life due to reduced airframe stress, improved high-altitude lateral stability, with an initial installation cost of $239,900.
