I don't understand, no one ever needed an LLM to automate air traffic controllers. 1980s tech could do that just fine. The reason they continue to exist is essentially cultural. Fell into a local maximum trap and now the entire industry and governance is incapable of lifting itself out of it and instead come up with stuff like "standardized phrases for the voice coms that we have inexplicably made crucial to the entire system" while riding cultural cliches like "the pilot must be in control" as they continue manual flight into big rocks.
