A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium (usually air or water). On an airplane, the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn
balance rudder Not usually a single rudder, but a set of three or four rudders operating together to maneuver a sternwheel steamboat. Placed just forward of the paddlewheels, the effectiveness of the balance rudder is increased by the flow of water generated by the paddles, giving such steamboats a high degree of maneuverability.

The rudder is a fundamental control surface which is typically controlled by pedals rather than at the stick. It is the primary means of controlling yaw—the rotation of an airplane about its vertical axis. The rudder may also be called upon to counter-act the adverse yaw produced by the roll-control surfaces.
An inboard rudder has a stock which passes through a gland in the hull, with the structure of the hull continuing towards the stern above the rudder. A spade rudder is hinged solely on the stock and has no lower bearing to help take the loads. Other rudder types may be hinged on an extension of the keel or on a skeg. Rudders may be balanced, by ...
A rudder command dictates changing the angle of the rudder, which is a single-event action, whereas steering a heading is a comparatively long event and will require ongoing or continuous rudder adjustments. The following are helm orders used in the United States Navy and United States Coast Guard: [2] Rudder. Midships (Bring rudder angle to 0 ...
WASHINGTON (Reuters) -The Federal Aviation Administration said on Tuesday it issued a safety alert to airlines warning of the potential for limited or jammed rudder movement on certain Boeing 737 ...
Together with the rest of the steering mechanism, it forms part of the helm (the term helm can mean the wheel alone, or the entire mechanism by which the rudder is controlled [1]). It is connected to a mechanical, electric servo, or hydraulic system which alters the horizontal angle of the vessel's rudder relative to its hull. In some modern ...
