The '''Stratus''' is a [[Germany|German]] single-place [[paraglider]] that was designed and produced by [[Swing Flugsportgeräte]] of [[Landsberied]]. It is now out of production.<ref name="WDLA04">Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 32. Pagefast Ltd, Lancaster OK, 2003. {{ISSN|1368-485X}}</ref>
==Design and development==
The Stratus was designed as a competition and cross country glider.<ref name="WDLA04"/>
The design progressed through eight generations of models, plus the Core and WRC, each improving on the last. The models are each named for their approximate projected wing area in square metres.<ref name="WDLA04"/>
==Operational history==
Reviewer Noel Bertrand noted the Status in a 2003 review for its high top speed.<ref name="WDLA04"/>
