The delta wing on Concorde uses elevon as its control surface. Is the elevon considered as all-moving control surface?
An All-Moving control surface is a surface where the complete structure acts as a stabilizer. For example, in case of a horizontal tailplane which can completely moved to work as Elevator (instead of just the trailing edge of the horizontal tailplane moving to work as a control surface). In such cases, it is called a Stabilator (Stabilizer + Elevator). Elevon is a control surface which is separate from the main wing and only the trailing edge of the wing is moved to get Yaw and Roll control. This makes Elevon a normal control surface and Not an all moving surface.
