Description du projet
Vers des vols plus écologiques
Les émissions de gaz d’échappement et de vapeur d’eau créant des traînées de condensation sont des facteurs majeurs du réchauffement climatique. Il est donc essentiel de réduire les émissions issues de l’aviation, mais d’une manière qui préserve la mobilité. Un moyen approprié de réduire les émissions à court et moyen terme consisterait à modifier la planification des trajectoires de vol et les opérations de contrôle du trafic aérien. Dans cette optique, le projet GREAT, financé par l’UE, vise à réduire la consommation de carburant et les émissions de gaz lors des phases de vol porte-à-porte. Il s’y attellera en développant et en évaluant un concept opérationnel de gestion du trafic aérien respectueux de l’environnement ainsi que des conceptions adaptées de l’espace aérien et des technologies écologiques d’optimisation des trajectoires, et en soutenant les systèmes avioniques. Le projet démontrera comment l’aviation pourrait réduire considérablement son impact sur le changement climatique en suivant cette approche.
Objectif
The perception of environmental problems especially global warming is more than ever an issue, especially in this day and age when reaching agreements on today's climate targets is a challenge and a topic of concern among European citizens of all ages. Associated effects of global warming, like extreme weather events, are driven primarily by the emission of exhaust gases (especially CO2, nitrogen oxides and methane) and water vapour creating contrails. Hence, reducing emissions to preserve the environment, while keeping the mobility is a central society need now and in the future. To reduce the emissions in short and medium term, changes in flight trajectory design and ATC operations are an appropriate means. Thereby, the flight trajectories are influenced on one hand by environmental and aircraft parameters, and on the other by ATC driven parameters, like route length or usable altitudes. During flight execution, re-planning on board of an aircraft using the flight management system enables to consider dynamic effects on the tactical level, like changes in the weather situation. For the efficiency of such a greener trajectory, it is necessary that the trajectory can be flown in the planned way, even under the actual traffic situation controlled by ATC, which today is often not the case. The overall objective of the cooperation of Chinese and European partners in GreAT is to reduce the fuel consumption and gas emissions during “gate-to-gate” flight phases through developing and assessing environment-friendly air traffic operational concept, adaptive airspace and green trajectory optimization technologies, and supporting avionic systems. Evaluation campaigns between the European partners and in combination with the Chinese partners through cross evaluations are planned to validate the proposed concept and show a potential significant reduction of the aviation’s impact on climate change.
