I am using dumpvdl2 for monitoring aircraft data. I am trying to identify the airport HEX codes so the name/place of ground station/airport displays. Here is a pic of my screen showing a HEX code to the right of "(Aircraft, On ground))…it seems some of the hex codes belong to the same GS. This is all new to me, I just started to use dumpvd2l along with acarsdec and dump-1090. Got all of them working, just trying to fine tune them. The hex code is 104CBA
Go to groups.io and join the vdl2/acars group. They keep up with all that information.
