==Design and development==
The Atis was designed as a beginner to intermediate glider.<ref name="WDLA04" />

The design has progressed through four generations of models, the Atis, Atis 2, 3 and 4, each improving on the last. The models are each named for their relative size.<ref name="WDLA04"/><ref name="sky-cz.com">{{cite web|url=http://www.sky-cz.com/vyrobky/padakove-kluzaky/atis-4-sng/atis-4.html|title=ATIS 4|author=Sky Paragliders|work=sky-cz.com|accessdate=11 November 2016}}</ref>
