In recent years, some research studies in Air Traffic Management (ATM) have proposed the idea of adjusting the speed of aircraft for several applications, like for instance, conflict resolution, 4D trajectory management, and airspace capacity and demand balance. In this paper an initial assessment on how this kind of speed variations may affect to fuel(More)
Contingency analysis and reaction is a critical task to be carried out by any airplane to guarantee its safe operation in a non-segregated airspace. Pilot’s reactions to any kind of incidences that may occur in-flight, like engine malfunctions, loss of electrical power, hydraulic failure, unexpected weather, etc, will determine the fate of the flight.(More)
This work introduces a flexible and reusable architecture designed to facilitate the development of remote sensing applications. Based on it, we are developing a helicopter system, called Red-Eye, devoted to the detection, control and analysis of wild land forest fires in the Mediterranean area. The design of the proposed system is composed of five main(More)
In this work it is presented a framework for a global optimization tool that will take into account aircraft dynamics and performances, noise nuisances and RNAV radionavigation requirements in order to assess an optimum flight depart or approach procedure. This strategy would be used as an optimization process performed by the corresponding authority in(More)
En route speed reduction can be used for air traffic flow management (ATFM), e.g., delaying aircraft while airborne or realizing metering at an arrival fix. In previous publications, the authors identified the flight conditions that maximize the airborne delay without incurring extra fuel consumption with respect to the nominal (not delayed) flight. In this(More)
This paper describes an aircraft trajectory optimisation algorithm that is part of the time and energy managed operations (TEMO) concept, a new trajectory planning and guidance strategy for advanced four dimensional (4D) continuous decent operations. In TEMO, a trajectory is planned in such a way that the best vertical trajectory profile is computed(More)
WEMSgen is a stand-alone application developed within the Clean Sky FASTOP (Fast Optimiser for continuous descent approaches) project that is capable to load weather data in standard GRIB (General Regularly-distributed Information in Binary form) files and generate piece-wise polynomial fitting functions that can be used in a latter stage in trajectory(More)
The sustained growth of air transportation traffic along the last decades has induced increasing noise exposure for the areas surrounding large and medium airports. This study concentrates on the optimization of the take-off and departure flight phase for a transportation aircraft. A general aircraft trajectory generation problem is first formulated as an(More)
