Garmin Announces Runway/Taxiway Safety Software - AVweb

So this is a step. But it doesn’t address aircraft that aren’t on ADS-B or an equivalent datalink for whatever reason - packet collisions, equipment failures, don’t have ADS-B out, etc. For autonomous aircraft in DoD, we are considering onboard sensors that can be used to independently do detections among other things that autonomous aircraft would need to do. And some sensors aren’t what you would normally think. Imagine a system that can listen to radios calls and infer that a problem is in the making like the runway incursion at Austin between Southwest and FedEx.
