Example Question From The Course:

CRP-1 – Calculating Distance Off-track From A VOR/DME

Your actual radial from the VOR is 155˚ and your desired radial you want to be on is 162˚. The DME range from the beacon is 17 NM. What is the distance off- track between the radials?

Step 1: Set index mark on the inner scale against the radial error on the outer scale. So in this case your radial error is 162˚ – 155˚ = 7˚.
Step 2: Move the red cursor over the DME range from the beacon on the inner scale.

Step 3: Read off the distance off -track on the outer scale. So in this case the distance off -track is 1.98 NM.
