Cost-Benefit Study of Free Flight with Airborne Separation Assurance

Self-separation corridors

“…International research provides evidence of the efficacy and benefits of delegating some separation authority to flight crews [20,21], but transition steps are required. This was acknowledged at the Eleventh Air Navigation Conference in Montreal: "To make delegation of separation possible, a number of building blocks in the current air transport system have to be adapted to the new applications.…”

A new solution for Markov Decision Processes and its aerospace applications

“…It was shown in previous work Hoekstra et al (2002); Bilimoria et al (2003) that free flight with airborne separation is able to handle a higher traffic density. Besides, free flight can also bring fuel and time efficiency Clari et al (2001). In a free flight framework, it is implied that aircraft will be responsible for their own separation assurance and conflict resolution.…”

Learning-based perception and control with adaptive stress testing for safe autonomous air mobility

“…In this dissertation, we consider a free flight airspace framework [Force (1995)] since it was shown in previous work [Hoekstra et al (2002); Bilimoria et al (2003); Consiglio et al (2007); Blom and Bakker (2015)] that free flight with airborne separation is able to handle a higher air traffic density even in the presence of various uncertainties and delays. In addition, free flight can also increase fuel and time efficiency [Clari et al (2001)]. In a free flight framework, it is implied that aircraft will be responsible for selfseparation assurance and conflict resolution [David J. et al (2001); Battiste et al (2002); Barhydt et al (2005)].…”
