Control surface, английский
Any moveable surface on an aircraft which controls its motion about one of the three principal axes. ailerons, elevators, and the rudder are examples of control surfaces. in addition, other type of roll control surfaces are roll spoilers that dump lift on one wing or another (as opposed to ailerons), spoilerons (combined spoiler and aileron), and flaperon (combined flap and aileron). other combined controls include the ruddervator (combined elevator and rudder as on the «v» tailed beech model 35), elevons combining elevator and ailerons and flailavators which control pitch & roll as well as flaps in wing trailing edge control surfaces. other subsidiary controls are pitch, roll, and rudder trim tabs and the adjustable pitch tailplane (the whole tailplane moves to trim the pitch axis).
