The navigation bridge of the Titanic. On the Titanic, the navigation bridge (or command bridge) was a superstructure where the ship's command was exercised.From this location, the officer on watch determined the ship's geographical position, gave all orders regarding navigation and speed, and received information about everything happening on board.
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 ships the wheel is replaced with a simple toggle that remotely controls an electro-mechanical or electro-hydraulic drive for the rudder, with a rudder position indicator presenting ...
[10] [2] Shortly after the orders for "LEFT, 20°" were given, a mate analyzed the rudder angle indicator and saw that the rudder was actually positioned at 10° to the right and was drifting further towards the right bank of the Brunswick River.

A professional helmsman maintains a steady course, properly executes all rudder orders, and communicates to the officer on the bridge using navigational terms relating to ship's heading and steering. A helmsman relies upon visual references, a magnetic and gyrocompass, and a rudder angle indicator to steer a steady course. The mate or other ...
The yaw string and slip-skid indicator ball show a slight slip with a positive sideslip angle. The pilot should apply right rudder pressure to correct. RIGHT TOP: Left turn slip should be corrected with left rudder pressure. RIGHT BOTTOM: Left turn skid should be corrected with right rudder pressure.
Typical trim tabs on aileron, rudder and elevator. Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force.
