Greetings to the VATSIM world!
Lately I’ve been hearing some strange callsigns, especially in Germany, which I would personally call unrealistic or even prohibited. Examples are DLH2A5 or DLHB2.
For me, a callsign is build out of the three letter code (e.g. DLH for Lufthansa) and up to 4 symbols (numbers and letters). It always has and starts with at least one number and can’t start with a letter. After the first number it can have up to 3 other symbols which may contain of only numbers or letters or a mix of them, but the order should always be numbers and then letters but never number|letter|number.
We’re obviously talking about IFR airline ops here and not VFR GA.
Unfortunately I haven’t found anything in the rules regarding this context. I’m also not a real life private or commercial pilot and not an air traffic conroller. However, I haven’t seen any callsign in my entire life that is structured like the two examples in the beginning.
I’m I wrong and is there somebody who can clarify that?
Thanks in advance!
