Once you have understood how to use the computer, you are equipped to solve

the tasks from the Distance Learning page.

Here is a little about how to find the crosswind component (CRP1W).

If the wind is 30° OFF, it

means 30° different from the

runway direction, so it is half

the crosswind.

Given is: runway 27 and wind

o
from 240 and 20 Kt.

We get:

crosswind 10 Kt headwind 18 Kt

With CRP1 we get with the same conditions:

If the wind is 30° OFF, meaning 30° different from the runway direction, then it

is half the crosswind.

o
Given is: runway 27 and wind from 240 and
20 Kt.

1) Set wind direction 240 under Index

2) Slide the slider so that the grommet is at

20 (= wind speed) on the straight

lines

3) Place a dot on the 0 mark

4) Now turn the dial so that the

course direction 27 is under Index

5) Read: headwind 18 Kt (vertical
distance from grommet to dot)

crosswind 10 Kt (horizontal distance from grommet to dot)
