Super-critical and Critical wing
Appreciate your answers. I heard the critical wing jargon being directed and assosiated with the Airbus aircraft. In a way it was due to the fact that the B767 / B777 does not have winglets and that most Airbus aircraft do. Thought it had to be because one was called a Super-Critical wing and the other a Critical. There may be incorect use of the wording or jargon due to what I have heard from other people. What makes a Airbus wing then need winglets and a B777 not ?
