NOTE: Aircraft equipped with ADS-B are also still required to have an operable transponder. The ATC-assigned beacon code is one of the required message elements of ADS-B Out.
NOTE: The computer will assign only discrete beacon codes unless all the discrete codes allocated to a facility are in use.
NOTE: This will provide the adjacent facility advance information on the aircraft and will cause auto-acquisition of the aircraft prior to handoff. When an airborne aircraft that has been assigned a beacon code by the ARTCC computer and whose flight plan will terminate in another facility's area cancels ATC service, appropriate action should be taken to remove flight plan information on that aircraft.
