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.

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.
