The most visible component of this paraglider, the sail, has been retained but certain aspects and mechanics of piloting this sail have been changed. La Cage has no brakes, accelerator or trims... 
 From the deltawing (Hang Glider) the Cage inherits the principle of   piloting by direct control of the attitude of the wing, in Pitch as well as in Roll; but only the principle, since the sail is not attached rigidly to a control bar.
 From those two ideas, the inventor, Jean Louis Darlet, create an original aircraft (which is not a hang-glider or a para-glider and thus requires a  specific training) which  both a very fine control of the attitude of his wing, and thus the benefit of exceptional flight characteristics, and an active security.
