Since airborne separation assurance is a fundamental principle of the FFA and the Airborne Separation Assurance System (ASAS) its main enabler, the AFA introduces the autonomous airborne separation assurance with AutonomousâASAS (AASAS). The AFA is marked by the machineâbased decisionâmaking, and the AFA is restricted to the ASAS and AASAS equipped aircraft but both types with autonomous flight capabilities. In the future the only humansâinâtheâloop conducting flight operations through AFA are going to be groundâ based UAS operators, air traffic flow managers of the next generation ATM, and systems supervisors (pilots of presentâday terminology) onboard remnant âoldâschoolâ manned aircraft. Based on 4D trajectory planning the AASAS concept covers machineâbased (a) traffic situational awareness, and (b) airborne spacing and selfâseparation assurance through (c) autonomous inâflight conflict detection and resolution.
