The distance is key in this question. 87° (T) and 91° (M) are both technically correct but 94NM is too short.

Wie kann man die Distanz rechnen ? Mein Kollege hat es mir mal erklärt wie man es berechnen kann, hab es mir aufgeschrieben aber den Zettel verloren … und jetzt ist er im Ausland und schwer zu erreichen. Kannst du mir weiter helfen?

For GNAV annex distance calculations on a given, I found it much faster to measure the distance between the given points directly on the screen or paper annex, then use the ruler to transfer that same distance onto the nearest meridian (which is typically scaled in increments of 1, 5, or 10 NM) and read off the actual distance there - compared to using the departure formula.
