How can I calculate a gradient using a Jeppesen Student Flight Computer?
It works the same way as with the CRP-5. If for example the ground distance and height above ground level is given, then one aligns the ground distance on the inner scale (the B scale) with the height above ground level on the outer scale (A scale). Then look up the number 10 or 10 mark on the inner scale (the CRP-5 has an additional red arrow for this mark), and read the gradient in percentage on the outer scale.
