Steering Wheels and Control Columns

Steering Wheels and Control Columns

 

control devices connected by linkage with the rudder of a ship, the elevator and ailerons of an airplane, or the road wheels of a machine such as a motor vehicle or a tractor.

The steering wheel of a ship is located in the pilothouse, and the control column of an airplane, in the cockpit. The steering wheel of a transport vehicle such as a motor vehicle is in the cab. Small ships have steering wheels that are operated manually, as are the control columns in light aircraft. Larger craft are equipped with auxiliary steering mechanisms, or boosters, which reduce to acceptable levels the force needed to turn the wheel or to operate the controls. The operation of the steering wheel on modern ships is fully automated and is facilitated by what is called aservomechanism.
