thanks for your work
GeoGebra is an interesting visualization tool.
„Kreuzeraufgabe“ is a term used for many navigational problems, „Aufkommen“, „Aufbleiben“, „Stellung einnehmen“ etc. I've learned that there are multiple solutions to the same problem. The solution they use is based on the methods of Walter Wunderlich. I prefer the methods from „Mathematik und Marine“ 1936's.
Case 2 „Aufkommen“ (v<u) you will find another solution in my video ,

I find this to be simpler, faster.
