The aircraft on takeoff roll has to abort and as you
know there could be a million reasons for that. Perhaps it's a non
mechanical reason, and therefore not known by the computer, a deer ran
on to the runway. How does the aircraft on final know what to do? It
all has to be inputted into a computer immediately.

If the computer is aware of the position of the aircraft it is
controlling through GPS interrogation, RADAR/transponder, ADDS-B, or
...., it would be programmed to issue the appropriate instructions to
the aircraft. Beyond departure and destination information, little
else need be "inputted" into the computer.
