A control horn is a section of control surface which projects ahead of the pivot point.  It generates a force which tends to increase the surface's deflection thus reducing the control pressure experienced by the pilot. Control horns may also incorporate a [[counterweight]] which helps to balance the control and prevent it from [[Aeroelasticity#Flutter|fluttering]] in the airstream. Some designs feature separate anti-flutter weights.

(In radio controlled model aircraft, the term "control horn" has a different meaning)<ref>{{Cite web |url=http://www.pc-control.co.uk/servo_control.htm |title="Servo Control" |access-date=2012-10-23 |archive-date=2017-09-16 |archive-url=https://web.archive.org/web/20170916201805/http://www.pc-control.co.uk/servo_control.htm |url-status=dead }}</ref><ref>[http://www.modelaircraft.org/mag/FAQ/answers/faq-q28.htm Model Aircraft: control horn FAQ] {{Webarchive|url=https://web.archive.org/web/20130513083300/http://www.modelaircraft.org/mag/FAQ/answers/faq-q28.htm |date=2013-05-13 }}</ref>
