for me, in working with the transponder codes for ATC/ATM. it is certainly interesting, if not entertaining that it appears that at least in this forum, pilots do not understand their equipment, and the ramifications...
changing codes in-flight???
thats lemming talk. do that in certain Countries, and they will just shoot you down...
Which countries are you referring too?
The discussion here is about the 12 bit Mode A code, not about the ICAO 24 bit address.
