The wing is widely used on Aeros trikes as well as by other [[ultralight aircraft]] manufacturers.<ref name="WDLA11">Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 198. WDLA UK, Lancaster UK, 2011. ISSN 1368-485X</ref>
==Design and development== The base model Profi wing is a [[Flying wires|cable-braced]], [[king post]]-equipped [[hang glider]]-style wing for two-place trikes, while the Profi TL is a "topless" design, lacking the king post and using streamlined lower [[lift strut]]s instead of wires. The topless design lowers the overall height of the wing and allows storage in lower-roofed hangars. A [[carbon fibre]] [[leading edge]] insert is optional, while [[winglets]] are standard on the TL model.<ref name="WDLA11" /><ref name="ProfiTL">{{cite web|url = http://www.aeros.com.ua/structure/trike/prfTL_en.php|title = The Aeros PROFI TL - another step forward! |accessdate = 19 February 2013|last = [[Aeros]]|year = 2005}}</ref>
The wing is made from bolted-together [[aluminium]] tubing, with its double surface wing covered in [[Dacron]] sailcloth. Its {{convert|10|m|ft|1|abbr=on}} span wing has an area of {{convert|14.5|m2|sqft|abbr=on}}, a nose angle of 128° and uses an "A" frame weight-shift control bar. An electro-mechanical trim is optional.<ref name="WDLA11" /><ref name="ProfiTLSpecs">{{cite web|url = http://www.aeros.com.ua/structure/trike/tkprfTL_en.php|title = Profi TL Performance|accessdate = 19 February 2013|last = [[Aeros]]|year = 2005}}</ref><ref name="ProfiSpecs">{{cite web|url = http://www.aeros.com.ua/structure/trike/tkprf_en.php|title = Profi Performance|accessdate = 19 February 2013|last = [[Aeros]]|year = 2005}}</ref>
