tailerons

tailerons

taileronsElevons mounted on the tail. These are aircraft control surfaces combining the effects of ailerons and elevators. Normally, these are used on delta and swept-back wing platforms and are located near the wing tips. The fore-and-aft movement of the control column causes the tailerons to operate together, which in turn rotates the aircraft about its lateral, or pitch, axis. If the control column is moved sideways, the tailerons move differentially—with one taileron going up while the other is going down—causing the aircraft to rotate about its longitudinal, or roll, axis.
