Tamarack Aerospace Group, a company founded in 2010 by aerospace structural engineer Nicholas Guida, has patented an Active Technology Load Alleviation System (ATLAS), a modified version of a wingtip device.<ref name=":1">{{Cite web|last=Gerzanics|first=Mike|date=October 23, 2019|title=ANALYSIS: ATLAS Citation separates winglet from 'blinglet'|url=https://www.flightglobal.com/analysis/analysis-atlas-citation-separates-winglet-from-blinglet/134703.article|access-date=2020-09-09|website=Flight Global}}</ref> The system uses Tamarack Active Camber Surfaces (TACS) to aerodynamically "switch off" the effects of the wingtip device when the aircraft is experiencing high-g events such as large gusts or severe pull-ups. TACS are movable panels, similar to [[Flap (aeronautics)|flaps]] or [[aileron]]s, on the trailing edge of the wing extension.<ref name=":1" /><ref name=":2">{{Cite patent|country=US|number=7900877B1|title=Active winglet|status=patent|pubdate=2011-03-08|gdate=2010-09-24|invent1=Guida|inventor1-first=Nicholas R.|url=https://patents.google.com/patent/US7900877B1/en}}</ref> The system is controlled by the aircraft's electrical system and a high-speed [[Servomotor|servo]] which is activated when the aircraft senses an oncoming stress event, essentially simulating an actuating wingtip. However, the wingtip itself is fixed and the TACS are the only moving part of the wingtip system. Tamarack first introduced ATLAS for the [[Cessna Citation family]] aircraft,<ref name=":1" /><ref name=":2" /> and it has been certified for use by the [[Federal Aviation Administration]] and [[European Union Aviation Safety Agency]].<ref>{{Cite web|last=Bergqvist|first=Pia|date=February 6, 2018|title=Tamarack Active Winglets Certified for Citation 525 Series|url=http://www.flyingmag.com/tamarack-active-winglets-certified-for-citation-525-series/|access-date=2020-09-09|website=Flying}}</ref><ref>{{Cite web|last=Finfrock|first=Rob|date=July 8, 2019|title=EASA Approves Tamarack Fixes To Lift Atlas Emergency AD|url=https://www.ainonline.com/aviation-news/business-aviation/2019-07-08/easa-approves-tamarack-fixes-lift-atlas-emergency-ad|access-date=2020-09-09|website=Aviation International News}}</ref>
