Tech Education 2 – Elevons.

On a conventional aircraft pitch is controlled by Elevators moving up or down to rotate the aircraft about it’s lateral axis, while the ailerons rotate it about the Longitudinal axis. Delta winged aircraft don’t have a tailplane, so on the trailing edge of the mainplane flying controls surfaces called ELEVONS (ELEVator+AilerONs)are fitted, these move together to provide pitch control, and in opposite directions to provide roll control. The cockpit controls are exactly the same, movement of the stick fore and aft controls pitch, and left to right controls roll.
