V-Tafel tables explanation

fisher_bcn · 01-30-24, 07:43 AM

I would like someone to explain to me how to interpret the v-tafel tables,
or to tell me if there is a tutorial in English;
I don't understand it in German,
and in Alpheratz's video I don't understand how he deduces that every 4 minutes
the bearing must be changed by 3-5º.
Thank you so much.

perform an internet search using f-tafel and you will find this resource.

don't ask me why UBI refers to it as v-tafel.

F-Tafel = Celestial Navigation
V-Tafel = Manoeuvre with distance speed and AOB

In the V-Tafel :

r = Seemeilen distance
y = AOB
Vu = our speed
Vg = target speed

With this you have all you need for manoeuvring with V-Tafel.

i am afraid that i will disappoint you because i use auto-targeting and not manual targeting.

I finally found the video where it explains how it works.

Definitely resolved.
Thank you so much.
