- How long (if at all) have US airline Boeing and Airbus planes been required to possess a 24 bit aircraft address for Mode S functions?
- How and where are these addresses set and contained? (the transponder unit, FMC, etc.)
- Although apparently forbidden, can such aircraft addresses be changed in mid-flight?
See:
EUROCONTROL - Mode S - Assignment of 24-bit aircraft addresses to State aircraft
Thanx!
