The title of this paper was chosen some time ago. In view of events experienced over the past three years on some modern civil jet transports, I propose to devote the time available to the subject of stall characteristics, together with some of the associated problems and with the methods of solution. Before anyone else raises the point, I wish to point out that the term “Super Stall” is nothing more than popular jargon and is equally as objectionable to the purists as “Deep Stall” or “Stable Stall”. It will, I hope, become clearer later as to what particular characteristics these terms apply.
