OICNW-A1.07 Compass – magnetic and gyro

Ability to determine errors of the magnetic and gyro-compasses, using celestial and terrestrial means, and to allow for such errors
Condition Behavior Standard

On a vessel underway using a standard azimuth circle,

the candidate reads the gyro-compass bearing of the sun and determines gyro- compass error. Electronic nautical almanac and celestial navigation calculation software may be used.

The candidate:

  1. Reads the azimuth of the sun when the repeater is level;

  2. Notes the time of the reading;

  3. Determines the true azimuth of the sun for the time of the reading;

  4. Compares the gyro-compass to the true azimuth and determines gyro error; and

  5. Determines gyro-compass error to within ± 1.0° of the assessor’s solution.
