Curso Relativo del Blanco con 3 Bearings
Simplemente alinea en la ventana inferior del cursor deslizable, el valor
de la diferencia B3 - B1 con el valor en la escal fija de la misma ventana de
B2-B1, y en la ventan superior, el cursor te indicara el Bearing desde
el blanco hacia vos, llamado Angle on Bow.

You ask... take the risk of my traslation !! :rotfl:

"Target Relative Course using 3 bearings.

Simply align.... in the slider cursor lower window the the value of the diference between Beaing 3 minus Bearing 1.... with the value into the fixed scale (dial) of the same window, corresponding to Bearing 2 minus Bearing 1.

And in the upper window the cursor will show you the bearing from the target position up to your position, called AOB."

or some thing similar.....


Take one bearing, call it B1

Wait few minutes, in example 5 min, take a second bearing, call it B2

Wait a same time as before, in example 5 min, take a bearing and call it B3.

Then obtain the degree diference between B3-B1, and B2 - B1

Align B3-B1 into the movile rule, with B2-B1 in the static rule....

Read the AOB into the Upper window....

You can do it matematically, here you have an exercise......
