Autonomous control systems—what does it really mean for aviation?

This 1,200-word piece is not intended to be a manifesto of advocacy for autonomous aircraft. Its purpose is to explain what autonomous control systems in general do, and—at a very perfunctory level—how they do it. It is not a blueprint for how to build one. But if nothing else, it shows that that real people like me actually have considered these things, and have figured out ways to do them successfully.
