Two ICARUS presentations at the 1st SESAR Innovation days

Luis Delgado and Enric Pastor will give a presentation each next December 2011.
Title: Simulation of airborne ATFM delay and delay recovery by cruise speed reduction
Authors: Luis Delgado, Xavier Prats,
SESAR innovation days
Air Traffic Flow Management (ATFM) regulations, such as ground holdings, are often cancelled before their initially
planned ending time. This early cancellation leads to an unnecessary ground delay and a misuse of airport or airspace resources. In previous publications, the authors have suggested a speed reduction strategy aiming at splitting the assigned ATFM delay between ground delay and airborne delay. If the aircraft flies at the minimum speed that gives the same fuel consumption as initially planned, the airline can maximise the airborne delay without any extra fuel consumption. If the regulation is cancelled before it was initially planned, the aircraft already airborne will be in a better position to recover part of the delay without incurring in additional fuel costs. In this paper, this speed reduction strategy has been simulated with the FACET tool for a whole day of flights inbound San Francisco airport (California). For each flight in the data set, it has been computed the maximum amount of airborne delay that can be performed. Moreover, the amount of delay that can be recovered has been also computed as a function of the time the regulation is cancelled. Preliminary results show, at first glance, a linear relationship between this cancellation time and the delay recovery which encourages as future work, to develop a parametric model of this delay recovery.

Title: Evaluation Technologies and Mechanisms for the Automated/Autonomous Operation of UAS in non-segregated airspace.
Authors: Enric Pastor, Pablo Royo, Marc Pérez-Batlle, Xavier Prats, Cristina Barrado
SESAR innovation days
This paper focuses on several aspects of the UASATM interaction that have not been previously addressed: separation assurance, contingency reaction and lost link procedures; as well as the evaluation of the trade-off between automated and autonomous UAS operations. These aspects will definitely determine the effectiveness of the UAS integration performing the aforementioned surveillance missions. Our research intents to investigate such relationships and how current ADS-B or future technology may support them. Beyond the conceptual perspective,
a simulation environment is being developed to provide functional and quantitative measures to the study of the UAS–
ATM interaction. UAS operations are modeled and reproduced in great detail through a wide set of real-time simulations. UAS behavior is being coupled with an ATC simulation environment that will allow to explore the UAS behavior to contingencies, conflicting traffic and ATC requests in real time.
