These lines go horizontally in the chart and they are called lines of latitude. Lines called meridians of longitude are drawn from pole to pole at right angles to the equator. These lines go vertically in the aeronautical chart. All of these lines together form a grid and any point of this grid can be found using numbers. The numbers represent degrees. There are 60 minutes to each degree and 60 seconds to every minute of a degree. The prime meridian, which is used as the zero degree line passes through Greenwich England. From this line measurements are made in degrees…
