Full autonomy in aircraft requires systems that can solve problems that are currently the exclusive domain of human cognitive function. Deep Neural Networks are the only feasible option we have today, but we need new methods to satisfy the burden of proof of airworthyness for the safety authorities. We will lay out the problem and propose directions in which to find the answer.
