The radar altimeter crisis of 2021–2022 shows that a new paradigm is needed to frame spectrum sharing between aircraft wireless systems and commercial wireless transmissions. Because impactful interference issues with many aircraft systems occur on takeoff and landing, ground-based wireless communication transmitters can be reconfigured to avoid interference impacts based on the flight path of the aircraft. A framework is discussed that uses a spatial-spectral broker co-located with air traffic control to parse resources for spectral and spatial use. This framework defines needed research in broker-based spectral coordination, propagation modeling, circuit and array reconfiguration techniques, and policy usage. The prescribed approach for spectral coordination will allow aircraft systems to ensure passenger safety to millions of passengers each day, while catalyzing the growth of wireless communication technologies to serve humanity on a wider global level.
