Tamarack Winglet Data Gets International Nods
The new aircraft flight manual supplement covers max weight increases, improved climb gradients, fatigue lie and maintenance, among other areas.

Tamarack Aerospace Group secured U.S. FAA, Brazilian ANAC and European Aviation Safety Agency approvals for a new aircraft flight manual supplement (AFMS) that outlines benefits for Cessna Citation 525-series aircraft equipped with Tamarack's Atlas active winglets. 


The AMFS and maintenance manual changes apply to Citation CJ, CJ1, CJ1+ and M2 business jets, and include a maximum zero fuel weight increase of 400 pounds; 8 to 15 percent increased climb gradient; a 600-pound higher mtow, on average, across hot/high tables; steep approach capability for authorized operators; wing fatigue life matching that of an unmodified aircraft; “on condition” maintenance of key Atlas components; and no altitude restriction for an inoperative yaw damper.


“Regulatory approval of this new performance data proves what our existing owners have known since their installs,” said Tamarack Aerospace founder and CEO Nick Guida. “Active winglets on the C525 dramatically enhance the performance of the aircraft. With Atlas you can climb faster, fly farther and burn less fuel.”


Tamarack is working with flight planning vendors to get updated data into flight planning tools, added Tamarack Aerospace president Justin Ryan. “Beyond range and time-to-climb, owners will also see the other benefits of Tamarack’s active winglets, such as stability and improved hot/high performance, aesthetics and value retention,” Ryan said. “This approved AFMS will now also allow commercial CJ operators to get the full benefits of their active winglets on a day-to-day operational basis, and additionally will be supplemented by cruise performance tables, which clearly show the performance advantages.”
