Levons
Levons, often written elevons, are aircraft control surfaces that combine the functions of an elevator (pitch control) and an aileron (roll control) into a single trailing-edge surface. They are primarily used on tailless aircraft and flying-wing configurations where there is no separate horizontal stabilizer.
In operation, elevons are located along the trailing edge of the wing and deflect in coordinated ways
Historically, the concept emerged with tailless and flying-wing designs in the mid-20th century. Elevons became a
Terminology can vary, and while elevon is the widely accepted term, levon is sometimes encountered as an
