|
|
|
The value of an angle.
|
|
|
The value of a bearing indication (at a given point) measured as the angle between the bearing and either True North or Magnetic North (this should appear explicitly or implicitly). The angle is measured clockwise from 0 degrees up to and including 360 degrees. The value can also be a VOR radial. For example, Westward is expressed as 270.
|
|
|
The value of an angle (at a given point) between the direction of Magnetic North and the direction of Geographical North. A positive value indicates that Magnetic North is East of Geographical North. A negative value indicates that Magnetic North is West of Geographical North.
|
|
|
The value of the annual rate of change of the magnetic variation. The unit of measurement would be degrees/year and can be positive or negative, i.e qualified by EAST (E) or WEST (W).
