Avoidance time at 100 meters with two aircraft with a closing speed 200kms is less than 2 sec.
So in that 2sec, onboard systems have to identify the threat, talk to the threat, determine and agree on a course of avoidance and carryout the avoidance climb, descent or turn.
I guess the software can do that in milliseconds but would the airframe be strong enough to survive the avoidance action, especially a passenger carrying airframe?
