Dear all,
I am learning to use the Jeppesen CR-3 for wind corrections calculations.
The manual reports two examples, rather clear to follow. Once the crosswind component has been identified, reading the value under the external wheel , in correspondence of the identified crosswind component will give the drift angle.
Anyway, the drift angle scale on the middle wheel from 10 degrees onward overlays on its own values: 10 deg lays on 1 deg, 15 deg is on top of 1.5 deg and so on.
In this situation, what is the criterion to choose the correct angle?
