SRS® is responsible for the wings ability to fly and launch at amazingly low speed despite its high wing loading, preventing the wing and pilot from stalling at critical angle of attack.
SRS® is the most effective tool in aiding automatic wing recovery in case of a stall (exclusive APCO invention - pat. pend.)
The principle of its function is based on change in C of G (Center of Gravity) when wing is stalled, creating an automatic mechanism for reduction in angle of attack for immediate recovery from stall - see sketch
SRS® is designed to be an important safety feature, but above all, it is a great help in improving launch characteristics on gliders when hesistating to come up over head.
