What are the 4 scales that are found on a course recorder paper?
This zone consists of four columns, each column corresponding to one quadrants 0-90, 90-180, 180-270 & 270-360.
What is Gyro Compass in ship?
A Gyro compass is a form of gyroscope, used widely on ships employing an electrically powered, fast-spinning gyroscope wheel and frictional forces among other factors utilising the basic physical laws, influences of gravity and the Earth’s rotation to find the true north.
What do you understand about non follow up?
A non-follow-up (NFU) lever has three distinct control positions. Centered, there is no rudder movement. Hold the lever to the left, and the rudder starts moving to the left. So rather than commanding a rudder position as you do with a FU control, you are commanding rudder movement with a NFU control.

A simple operation which can be done any time by putting the switch form ‘Auto’ to ‘Manual’. The steering must be changed from ‘Auto’ to ‘Manual’ once every watch and ship hand steered for some time before retuning to ‘Auto’.
What is course recorder on ship?
Course Recorder: This is a graphic record keeping device which can record all gyro courses steered by the ship throughout the voyage. It has a built-in clock which keeps time accurately (on older ships this clock is a winding type but on modern ships it is usually electrical or quartz).
Which of the following is marked by course recorder?
Course recorder is navigational equipment for automatically recording the course of vessel over period of time. The record is done on continuous paper belt. The recorder is operated from a gyro compass or a remote magnetic compass. Features of course recorder are as follow.
What are the advantages of magnetic compass?
Explanation: They have two main advantages over magnetic compasses: they find true north, i.e., the direction of Earth’s rotational axis, as opposed to magnetic north, they are not affected by ferromagnetic metal (including iron, steel, cobalt, nickel, and various alloys) in a ship’s hull.
What is the working principle of gyro compass?
Gyrocompass, navigational instrument which makes use of a continuously driven gyroscope to accurately seek the direction of true (geographic) north. It operates by seeking an equilibrium direction under the combined effects of the force of gravity and the daily rotation of Earth.
