Overall Course Objectives
This course covers the magnetic compass, gyroscopic compass, fluxgate compass, automatic pilot, rate of turn indicator and speed &distance log instruments. That course provide the candidate the understanding of the theory of operation and how to use all indicated instruments for safe and efficient navigation. In the aspect of getting the candidate well familiar with different methods of calculating the errors which can be obtained from the compasses and comparing between the readings of them, and also will be familiar with the theory of operation of the gyroscopic compass and how it work in addition it will help him to understand the theory of operation of the rate of turn indicator ,fluxgate compass ,speed & distance log instruments and the different methods of using Auto Pilot for steering and control the ship in order to deal with a potentially hazardous situation. It does this by giving information on the understanding and safe use of such instruments.
On completion of this courses the student will be able to :
• Use the magnetic compass, gyroscopic compass, fluxgate compass, automatic pilot, the rate of turn indicator and speed &distance log instruments in the proper way to have a safe and efficient navigation.
• Calculating the errors which can be obtained from the compasses.
• Make frequently adjustment, checking and routine maintenance of these instruments.
• Understand how the ship's compasses are calibrated and treated.
Knowledge and Understanding
At the end of the course, students should be able to:
• Understand the basic theory and use of the magnetic compass, gyroscopic compass, fluxgate compass, automatic pilot, rate of turn indicator and speed &distance log instruments.
• Understand the operation procedure of the gyroscopic compass, fluxgate compass, automatic pilot, rate of turn indicator and speed & distance log instruments.
