(2020-03-03)
Article
Restricted access - publisher's policyThis paper proposes a collaborative air traffic flow management (ATFM) framework, in the scope of trajectory based operations, aiming to improve the cost-efficiency for airspace users (AUs) when facing ATFM regulations. ... -
Alternative Trajectory Options for Delay Reduction in Demand and Capacity Balancing
(2018)
Conference report
Open AccessAiming to a more collaborative demand and capacity balancing (DCB), in the scope of trajectory based operations, this paper presents an approach that takes alternative trajectories into a DCB optimization algorithm. ... -
APACHE - Report on the availability of the APACHE framework
(2018-07-25)
External research report
Open AccessThe APACHE project proposes a new framework to assess European ATM (air traffic management) performance based on simulation, optimization and performance assessment tools that will be able to capture the complex interdependencies ... -
Climb, cruise, and descent speed reduction for airborne delay without extra fuel
(2018-05-01)
Article
Open AccessIn 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 ... -
Cost-based linear holding practice and collaborative air traffic flow management under trajectory based operations
(Universitat Politècnica de Catalunya, 2018-11-20)
Doctoral thesis
Open AccessThe current air transportation system is reaching the capacity limit in many countries/regions across the world. It tends to be less efficient or even incapable sometimes to deal with the enormous air traffic demand that ... -
Effects of linear holding for reducing additional flight delays without extra fuel consumption
(2017-06)
Article
Open AccessThis paper presents an approach to implement linear holding (LH) for flights initially subject to ground holding, in the context of Trajectory Based Operations. The aim is to neutralize additional delays raised from the ... -
Effects of speed reduction in climb, cruise and descent phases to generate linear holding at no extra fuel cost
(2016)
Conference report
Open AccessSpeed reduction strategies have proved to be useful to recover delay if air traffic flow management regulations are cancelled before initially planned. Considering that for short- haul flights the ... -
Enhanced Demand and Capacity Balancing based on alternative trajectory options and traffic volume hotspot detection
Conference report
Open AccessNowadays, regulations in Europe are applied at traffic volume (TV) level consisting in a reference location, i.e. a sector or an airport, and in some traffic flows, which act as directional traffic filters. This paper ... -
Including linear holding in air traffic flow management for flexible delay handling
(2017)
Conference report
Open AccessThis paper introduces a strategy to include linear holding into air traffic flow management (ATFM) initiatives, together with the commonly used ground holding and airborne holding measures. In this way, ATFM performance ... -

Article
Open AccessThis 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 ... -
Integration of ground, airborne and linear holding for a cost-efficient network air traffic flow management
(2017)
Conference report
Restricted access - publisher's policyThis paper presents a method to integrate a cost-based linear holding (LH) practice, with the commonly seen ground and airborne holding, for the network air traf¿c ¿ow management (ATFM) problem. In this method, the performance ... -
Linear holding for airspace flow programs: a case study on delay absorption and recovery
(2018-08-07)
Article
Open AccessThis paper presents a method to introduce linear holding to flights affected by Airspace Flow Program (AFP) initiatives. Trajectories are optimized at their planning stage in such a way that the program performance is ... -

(2017)
Conference lecture
Restricted access - publisher's policyThis paper presents a method to implement linear holding (LH) for flights subject to ground holding in context of the upcoming Trajectory Based Operations in air transportation, aimed at reducing additional delays raised ... -
Maximizing airborne delay at no extra fuel cost by means of linear holding
(2017-08-01)
Article
Open AccessThis paper introduces a linear holding strategy based on prior works on cruise speed reduction, aimed at performing airborne delay at no extra fuel cost, as a complementary strategy to current ground and airborne holding ... -
Synchronised Demand-Capacity Balancing in Collaborative Air Traffic Flow Management
(2020-05)
Article
Open AccessThis paper introduces a novel approach for synchronised demand-capacity balancing within a proposed Collaborative Air Traffic Flow Management framework. The approach is aimed to realise optimising traffic flow and scheduling ... -
