"I feel like there is a bit missing here that is not totally clear or not made explicit enough," says Jake. "The part of observability is a big problem in airplanes because you really can't observe your own speed in many ways." The next section, where we get to ultra-state systems, follows on from what Rudy was just saying about the sensing decision and then acting. We talk a little bit about internal stability disturbances and then get to the concept of ultra-stable systems.
