Probabilistic Analysis of Aircraft Fuel Consumption Using Ensemble Weather Forecasts
(International Conference on Research in Air Transportation (ICRAT), 2016-06-20)
The effects of wind uncertainty on aircraft fuel consumption are analyzed using a probabilistic trajectory predictor. The case of cruise flight subject to an average constant wind is considered. The average wind is ...

Optimal Aircraft Path Planning Considering Wind Uncertainty
(The European Conference for AeroSpace Sciences (EUCASS), 2017-07)
The optimization of the aircraft route taking into account wind uncertainty is addressed in this work. The wind uncertainty is obtained from ensemble weather forecasts. A structured airspace is considered, which is defined ...

Aircraft trajectory optimization using singular optimal control theory
(2014)
The optimization of aircraft trajectories using the theory of singular optimal control is studied in this thesis. To describe the aircraft motion, a general nonlinear 3-degree-of-freedom point-mass model is adopted, along ...

Analysis of the Effect of Uncertain Average Winds on Cruise Fuel Load
(SESAR Joint Undertaking, 2015-12-01)
The required fuel load of an aircraft for a given cruise range with uncertain average wind (modelled by a uniform distribution) is studied in this work. The fuel mass probability density function is obtained using an ...

Propagation of Initial Mass Uncertainty in Aircraft Cruise Flight
(American Institute of Aeronautics and Astronautics Inc., 2013-03)
The propagation of initial mass uncertainty in cruise flight is studied. Two cruise conditions are analyzed: one with given cruise fuel load and the other with given cruise range. Two different distributions of initial ...
