Study Notes
Course Recorder Overview
- Installed on the bridge to record gyro courses during the voyage.
- Utilizes a built-in timer, typically a winding clock, to timestamp records accurately.
- Essential for providing evidence in accident or collision cases.
- Must be correctly set prior to departure and ensure proper recording.
Inputs to the Course Recorder
- Gyro Compass Connection: One repeater linked to the course recorder manages signals for the spiral grooved drum, controlling the movement of the course stylus.
- Clock Functionality: Connected to the paper feed roller, this clock regulates the speed at which paper moves under the stylus, ensuring alignment with time graduations.
Stylus and Recording Paper
-
Stylus Types:
- Older models use ink pens requiring weekly refilling with slow-drying ink.
- Modern course recorders like Anschutz utilize conductive wires that mark the paper directly upon contact with the metal plate.
- Paper Specifications: Supplied in rolls, installed following manufacturer’s guidelines, and typically feeds vertically from top to bottom.
-
Graph Paper Design:
- Time Scale: Located on the left side, permits setting correct GMT (though practices may vary).
- Course Section: Positioned centrally, marked in quadrants for detailed course reading, allows measurement to the nearest degree.
- Zone Section: Found on the right side, consists of four columns to clarify quadrant identification, helping to prevent ambiguity in course recording.
