| This project aims to obtain flight distance statistics for
different European routes, times of the day, airlines, and winds. These statistics will then be used to generate a model relating the great circle distance (GCD) and the "real" flight distance. Estimates of error will be computed and compared to corrections usually applied on the GCD to get the real flight distance, such as the one used by the ICAO. This model will be useful to evaluate flight efficiency and to serve as an input in models computing flight emissions. |

| Overview (resum en anglès): | |
| The main objective of this project is to create models and study the real flight
distance, horizontal and vertical flight efficiency, fuel consumption, and emissions, for short and medium-haul flights in Europe, based on real flight data obtained from ADS-B readings, using the online application Flightradar24. With most studies on consumption and emissions relying on the great circle distance (GCD) to measure the flight distance in air operations, the need to better adjust the flight time and flight distance to reality arose. To do so, all the input data on which this project is based on corresponds to real commercial flights that took place in Europe, between October 2021 and May 2022. After collecting and processing the data using software tools such as Matlab and Excel, a model was created to better understand which factors affect the flight distance. These models can be useful to, for example, study the possibility of intermodality, a solution that proposes that some flights are replaced by more sustainable transport models, such as the train. Then, the real flight distance and maximum flight level are compared to the GCD and the reference altitude respectively, to find the Horizontal Flight Efficiency (HFE) and Vertical Flight Efficiency (VFE). Finally, a fuel consumption, and consequently, an emission study, is carried out not to only find out the relationship between emissions and flight efficiency, but also to assess how different air traffic management (ATM) solutions, such as free route airspace or continuous descent operations affect the consumption and emissions. The results obtained allow the user to, knowing the GCD between two airport pairs, find an estimation of the real flight distance and greenhouse gas emissions. Additionally, after assessing the current situation in European airspace regarding flight efficiency, it is studied if the defined ATM solutions indeed reduce, and how much, the fuel burnt and emissions. |
