Short summary: It was not so easy to determine accurate positions in the beginning of the war due to technical limitations and short signals (<20s).

I wasn't aware that you can determine the direction only with one measurement point, but using the loops make sense. But still, the presence of uboat nearby (source of radio signal in coded german) should put the escort in some kind of alert state. At least to call an air support (if available) to investigate. Or I still missing something.

I remember that the important air operation are conducted in radio-silence just to avoid an early warning.

The question in the same vibe. Submarine can't send a message while submerged, but can it receive one? Probably not, so how the BdU orders are communicated to them -- are they repeated until the submarine acknowledge it?

10. Can you show a screenshot? It's been a while since I looked at the Magui interface. I can imagine 2 wheel indicators with a time scale used for calculation (of speed).

Thanks. I will try when I get home.
Concerning the Zeit calculator, it is on backside of attack disk screenshot in this tread.
Speed and time estimations are a headache for me, so I'm really interested in everything with zeit written on it.
