If a gradient in % is required, the numbers work out with the same rule: 1% over 1 NM ≈ 60' It is also useful to find out the lateral deviation from a given VOR course or radial: Each dot on a VOR indicator represents 2° of deviation, or 200' per dot per DME. There are other applications to this rule. One such application is time drift.
