    Nava Gaxiola, Cesar Antonio; Barrado Muxí, Cristina; Royo Chic, Pablo; Pastor Llorens, Enric (2018-09-07)
    Article
    Accés restringit per política de l'editorial
    Free Route Airspace is an operational concept for the modernization of the airspace, addressed to improving the efficiency of the flights. It also aims at the environmental friendly performance area by reducing the emissions ...
  • Towards high performance robotic computing 

    Camargo Forero, Leonardo; Royo Chic, Pablo; Prats Menéndez, Xavier (2018-09-01)
    Article
    Accés restringit per política de l'editorial
    Embedding a robot with a companion computer is becoming a common practice nowadays. Such computer is installed with an operatingsystem, often a Linux distribution. Moreover, Graphic Processing Units (GPUs) can be embedded ...
  • Including linear holding in air traffic flow management for flexible delay handling 

    Xu, Yan; Prats Menéndez, Xavier (2017-10)
    Article
    Accés obert
    This paper introduces a strategy to include linear holding into air traffic flow management initiatives, together with the commonly used ground holding and airborne holding measures. In this way, flow management performance ...
  • Climb, cruise, and descent speed reduction for airborne delay without extra fuel 

    Xu, Yan; Dalmau Codina, Ramon; Prats Menéndez, Xavier (2018-05-01)
    Article
    Accés obert
    In the majority of situations, air traffic flow management (ATFM) regulations are issued due to weather-related capacity reductions. Considering the uncertainties in weather prediction and other unforeseen factors, ATFM ...
  • A macroscopic performance analysis of NASA’s northrop grumman RQ-4A 

    Pastor Llorens, Enric; Pérez Batlle, Marcos; Barrado Muxí, Cristina; Royo Chic, Pablo; Cuadrado Santolaria, Raúl (Multidisciplinary Digital Publishing Institute (MDPI), 2018-01-10)
    Article
    Accés obert
    This paper presents the process of identification, from a macroscopic point of view, of the Northrop Grumman RQ-4A Global Hawk Remote-Piloted Aircraft System from real, but limited flight information. Performance parameters ...
  • General queuing model for optimal seamless delivery of payload processing in multi-core processors 

    Salamí San Juan, Esther; Barrado Muxí, Cristina; Gallardo Gómez, Antonia; Pastor Llorens, Enric (2017-07-10)
    Article
    Accés obert
    Recent developments in unmanned aerial systems (UAS) provide new opportunities in remote sensing application. In contrast to satellite and conventional (manned) aerial tasks, UAS flights can be operated in a very short ...
  • Influence of meteorological phenomena on worldwide aircraft accidents in the period 1967-2010 

    Mazón Bueso, Jordi; Rojas Gregorio, José Ignacio; Lozano, Miguel; Pino González, David; Prats Menéndez, Xavier; Miglietta, M.M. (2017-12-01)
    Article
    Accés obert
    Based on the information available in databases from relevant national and international organizations from 1967 to 2010, an Aviation Weather Accidents Database (AWAD) was built. According to the AWAD, the weather is ...
  • Hardware design of a small UAS helicopter for remote sensing operations 

    Royo Chic, Pablo; Pastor Llorens, Enric; Barrado Muxí, Cristina; Cuadrado Santolaria, Raúl; Barrao, Félix; Garcia, Antonio (MDPI AG, 2017-09-10)
    Article
    Accés obert
    This paper presents the hardware design and integration process employed to develop an Unmanned Aircraft System (UAS) helicopter. The design process evolves from the bare airframe (without any electronics), to become a ...
  • Controlled time of arrival windows for already initiated energy-neutral continuous descent operations 

    Dalmau Codina, Ramon; Prats Menéndez, Xavier (2017-12-01)
    Article
    Accés restringit per política de l'editorial
    Continuous descent operations with controlled times of arrival at one or several metering fixes could enable environmentally friendly procedures without compromising terminal airspace capacity. This paper focuses on ...
  • Assessing the impact of relaxing cruise operations with a reduction of the minimum rate of climb and/or step climb heights 

    Dalmau Codina, Ramon; Prats Menéndez, Xavier (2017-11-01)
    Article
    Accés restringit per política de l'editorial
    A compromise solution to increase flight efficiency in cruise, but without penalising capacity (or even safety), would be perhaps to remove (or relax) the minimum rate of climb (ROC) constraint and/or to reduce the height ...
