The control surfaces, rudder, elevators and ailerons.
The rudder
A lever used to turn a rudder is typically called a tiller. It is a long handle attached to the top of the rudder post and is used to control the direction of the boat by moving the rudder.
Small boats use a bar attached to the rudder to steer. Larger boats and ships will use a wheel and rope or chain system to control the rudder.
No, the rudder does not control the pitch of an aircraft. The rudder is primarily used for controlling yaw, which is the side-to-side movement of the aircraft's nose. Pitch is controlled by the elevator, which is located on the tail of the aircraft and adjusts the angle of the plane's nose up or down.
There is no horizontal rudder. The horizontal control surface is the elevator. The rudder steers, elevator makes the plane go up and down
Rudder handles are commonly referred to as "tiller" or "tiller handles." In nautical terms, a tiller is a lever used to steer a boat by controlling the rudder's position. In some contexts, particularly in aviation, they may also be called "rudder pedals" or "rudder control sticks," depending on the specific mechanism used for controlling the rudder.
The main control stick and rudder pedals are used to move the control surfaces.

A rudder typically consists of several key parts: the blade, which is the vertical surface that directs water flow; the stock, a vertical rod that connects the blade to the steering mechanism; and the gudgeon and pintle, which are hardware components that allow the rudder to pivot. Additionally, there may be a rudder post that reinforces the structure and a control system, such as a wheel or tiller, used to maneuver the rudder. These components work together to provide directional control for boats and ships.
to be able to steer a ship with complete control. without ship rudder many people would tip over when there on a boat.
