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 or on a simulator equipped with both a magnetic and gyro- compass, and given a deviation table, and a chart with a scale of no more than 1:150,000,

the candidate correctly applies the compass error to the compass bearings by magnetic compass of at least two charted objects and plots them on the chart in use.

The candidate:

  1. Correctly applies compass error to the magnetic compass bearings; and

  2. Determines the objects’ position to within ± 1.0° of the assessor’s solution.
