Spoileron

A raised spoileron increases the drag on the down-going wing where it is deployed, causing the aircraft to yaw in the direction of the turn.

The Mitsubishi MU-2 has double-slotted flaps that take-up the full length of the wing, to achieve good STOL performance.

The spoilers, situated inboard and forward of the trailing edge, are used for lateral control at high speeds to prevent excessive wing twist.

They double as spoilerons that assist the ailerons when the pilot commands a high roll rate.
