A Collaborative Trajectory Management Framework in Case of Single Pilot Operation Disability: Considering the Overall Safety of Air Traffic System

Single pilot operation (SPO) is an important development direction of next-generation commercial aircraft. Developing SPO first needs to solve a series of operation safety problems, including the circumstance that single pilot loses the ability to operate aircraft (SPO disability). SPO disability not only bring safety influence to the aircraft itself, but also to the air traffic system, which requires further collaborative decision-making (CDM) by air navigation sevice provider (ANSP) and airline. For this, this paper proposes a collaborative trajectory management framework in case of SPO disability by integrating SPO with trajectory-based operation (TBO), and introduces some adjustments needed for trajectory optimization model and algorithm. Finally, an example is constructed to further illustrate this framework.
