Inserting a legend onto an ADMIRALTY Standard Nautical Chart
Summary
TLDRThis instructional video script outlines the process of inserting a legend on a chart. It instructs viewers to use a grid box for positioning, mark the legend's text lines with a 7H pencil, and then trace over with a 2B pencil and ruler for guidelines. The legend text should be written with a magenta 1 18 pen, ensuring clear distinction between upper and lower case letters. The script emphasizes that legends should be horizontal unless specified otherwise. Finally, it details how to check the legend's placement and update the chart's Notices to Mariners section.

Q & A
What is the purpose of using a grid box in the context of the script?
-The grid box is used to reference the NM (Nautical Mile) position on the chart, which helps in accurately placing the legend on the chart.
Why are latitude and longitude guides used in the process described?
-Latitude and longitude guides are used to trace and place the legend on the chart at its exact location, ensuring accuracy in positioning.
What type of pencil is recommended for marking the start and end of lines of text on the chart?
-A 7H pencil is recommended for marking the start and end of all lines of text within the legend onto the chart.
Why is it necessary to remove the tracing after marking the text lines?
-The tracing is removed to reveal the chart underneath, allowing for the drawing of guidelines and the writing of the legend text without the tracing obstructing the process.
What tools are used to draw guidelines between the marked points on the chart?
-A 2B pencil and a ruler are used to draw guidelines between the marked points for each line of text on the chart.
Which pen is specified for writing the legend text, and what color should it be?
-A magenta 1 18 pen is specified for writing the legend text, ensuring clear and distinguishable writing.
Why is it important to distinguish between upper and lower case when writing the legend text?
-Distinguishing between upper and lower case is important for clarity and to ensure that the legend text is written accurately as it appears on the tracing.
What is the rule regarding the orientation of legends on a chart?
-Legends should always be written horizontally unless the textual NM instructs otherwise, indicating that the orientation should follow specific instructions if provided.
Why is it necessary to erase all pencil markings after completing the legend insertion?
-Erasing all pencil markings is important for a clean and professional final appearance of the chart, ensuring that no temporary markings remain.
How can one verify that the legend has been inserted in the correct position on the chart?
-By laying the tracing back over the chart, one can check that the legend has been inserted in the correct position, ensuring accuracy in the final product.
Where should the NM update number be added once all updates to the chart have been applied?
-The NM update number should be added to the chart's Notices to Mariners section, located in the bottom left corner of the chart.

📈 Inserting a Chart Legend
This paragraph provides a step-by-step guide on how to insert a legend onto a chart. It begins with using the grid box to locate the NM position and then marking the start and end of text lines with a 7H pencil. Afterward, guidelines are drawn between these points with a 2B pencil and a ruler. The legend text is then written using a magenta 1 18 pen, ensuring clear distinction between upper and lower case letters. It is emphasized that legends should be written horizontally unless specified otherwise. Once the legend is correctly placed, pencil markings are erased, and the tracing is checked for accuracy. Finally, the NM update number is added to the chart's notices to Mariners section.
