For Immediate Release
Sandpoint, Idaho, 10th October 2016 Tamarack Aerospace announces its recently certified Active Winglet Technology far exceeds the newly adopted ICAO standards in three significant ways. Firstly aircraft fitted with Tamarack Active Winglets can expect a significant 15-25% reduction in fuel burn. Secondly Active Winglets can be retrofitted to any aircraft type, which means existing fleets can be made significantly more efficient. Lastly, the Active Winglet technology exists today and can be applied well in advance of the mandatory implementation dates.
This month ICAO introduced two landmark global initiatives aimed at tackling aviation’s contribution to climate change. The first is a carbon offset, or trading scheme, to help manage aviation’s carbon footprint. The second is a carbon dioxide efficiency standard aimed at encouraging the integration of fuel efficient technologies.
The CO2 standard applies to all new aircraft type-certificated after January 1, 2020, and to aircraft currently in production from 2023, but only if those designs are modified in a way that requires re-certification. All remaining aircraft in production will have to comply by 2028. The standards do not apply to existing aircraft and do not require retrofit.
Tamarack’s revolutionary Active Winglets system consist of 3 components and require absolutely no wing reinforcement. The system is comprised of; a wing tip extension; a load alleviation device; and a highly tuned winglet. This combination significantly increases the aspect ratio and hence efficiency of the wing. Key to the design is the patented load alleviation technology. Tamarack’s revolutionary technology detects gust and maneuver loads that could exceed the aircraft’s design loads and counteracts them almost instantaneously.
Tamarack founder and Active Winglet inventor, Nick Guida states: “Climate change is something that affects us all, and the ICAO initiative is a step in the right direction. However, the aviation industry could make significantly more progress today, by adopting Tamarack’s Active Winglet technology. Waiting decades for inefficient aircraft to be replaced with more efficient models makes no sense when a solution is currently available for retrofit. To that end, we are actively engaging with; airlines, airframe manufactures, private jet owners and the military sector to share this game changing technology.”
Tamarack has accumulated more than 400 hours of flight test data on an Active Winglet equipped Cessna Citation 525. Those flight tests have proven a 25% reduction in fuel burn. Newer aircraft, such as the Cessna CJ1+, see a reduction in fuel burn of up to 12 percent.
Computer modelling, and flight analytic models show a mid-sized jet such as the 737 (even those already fitted with ‘passive’ winglets) fitted with Active Winglets can expect a 15% overall reduction in fuel burn.
New aircraft designs would also benefit by incorporating Tamarack’s Active Winglet technology. New wings could be designed from the outset without the heavy additional structure passive winglets require, while gaining all of the aerodynamic and fuel efficiencies of a winglet.
Tamarack COO Brian Cox states: “ICAO set standards are based on what the industry might technologically and economically achieve at a future date – but the future is now. Tamarack’s Active Winglets match improvements equivalent to retrofitting aircraft with the latest generation of efficient engines, and at a fraction of that cost. Tamarack Active Winglets for commercial aircraft will pay for themselves in fuel savings in less time than passive winglets by saving 3 to 4 times more fuel on every flight.”
Active Winglets have been certified by EASA for the Cessna Citation CJ, CJ1, CJ1+ & M2. FAA approval is expected towards the end of 2016.

Tamarack Aerospace has certified the next generation of winglets, which are three to four times more efficient than previous types. The patented design, ‘Active Technology Load Alleviation System’ or ATLAS™, is made up of a wing tip extension, a highly tuned winglet, and a load alleviation system that counteracts the additional loads induced by the winglet in rare peak-loading events such as a gust or manoeuvre. This means that heavy wing reinforcement is not required, thus increasing efficiency and significantly reducing retrofit times. ATLAS Active Winglets are scalable and can be installed on any aircraft type.
In 2013, Tamarack flew 1853nm (with only a 26 kt tailwind) in a Cessna CJ using ATLAS Active Winglets – an (unofficial) world record for distance flown in this category of aircraft.
