|Control Sheet#||Task||Assessment Method:|
|OICNW-1-1A||Adjust a sextant: Remove Perpendicularity; Side Error; Parallelism; and Collimation Error.||Practical demonstration|
|OICNW-1-1B||Measure the altitude of the Sun and accurately record the time of the observation.||Practical demonstration|
|OICNW-1-1C*||Measure the altitude of any combination of three stars, planets and/or moon and accurately record the time of the observations.||Practical demonstration|
|OICNW-1-1D||Measure the altitude of the Sun at meridian passage (local apparent noon) and accurately record the time of the observation.||Practical demonstration|
|OICNW-1-1E||Celestial running fix: Plot at least 3 celestial lines of position (LOPs), advance them to a common time and determine the position.||Examination problem|
|OICNW-1-1F||Star fix: Plot at least 3 celestial lines of position (LOPs), advance them to a common time and determine the position.||Examination Problem|
The Practical demonstration period for OICNW-1-1C is conducted during a time frame outside of the normal course schedule hours at either morning or evening twilight (star time), times are at the instructor/assessor discretion. Those that complete this course need not present completed “Control Sheets” for these assessments in application for STCW certification.
