On airport diagrams, aerodrome charts, and some instrument approach procedures (IAPs), magnetic north arrows appear in the layout. These arrows provide directional awareness and depict the orientation of True North, magnetic variation, and grid variation for a particular airport. The arrows consist of two main types of elements: a magnetic variation arrow and a magnetic and grid variation arrow. These arrows are drawn based on the airport's coordinates or the center of the data frame using the World Magnetic Model.
