When you get on a passenger aircraft, we assume that it’s been undergoing regular maintenance and pre-flight checks. But what about unmanned aircraft? We check that the propellers are okay, that the battery isn’t cracked or puffy, and that there’s nothing amiss with the fuselage, with more detailed checks for commercial operators. But how do you do it at scale? What about drone swarms, or fleets of autonomous drones? NASA recently posted about the Fit2Fly initiative. What if a drone could “sign-off” with a standard, recognized digital certificate that offers assurances it’s safe to be in the air? The system combines data that the drone can gather itself, with human generated input for other periodic maintenance, to keep drones in compliance.
