How does a single pilot taxi? Cameras? Center seat? Robo-tug to runup area?
Will ATC issue instruction directly to the flight control system?
Is aviation coding, hardware and software and comm infrastructure secure and free of jams or saturation?
How is onboard radar offboarded to a "superdispatcher" or ground-based pilot?
Is there bandwidth for modern buffer-filling radar offboarding? If not- who pays/provides?
Looking ahead- Can manned and unmanned share the exact same flight profiles like two separate manned flights today?
