> Shouldn’t there be a universal standard to communicate clearances to the computer systems of the airplanes and other runway vehicles? “Communicating clearances” would actually be the easy part. The hard part is making sure that there actually is clearance. The system would need to be able to “see” the runway and to “know” about the flights that are permitted to use it in real-time. It would involve many computers, some in the air and some on the ground I assume. If the system failed the pilots would have to fall back onto something else, perhaps what they do today, so they’d still need training and practice. If a pilot made a mistake the system would need to be able to detect that and update everyone.
