The EGU General Assembly is a forum that brings together scientists to present their work and discuss their ideas with experts in all fields of geoscience. The EGU23 will take place in Vienna, Austria and online on the 23–28 April 2023, and the Aircraft Operations Lab is participating with two conference papers.
Both of the papers will be part of the session ITS1.2/AS5.14 – “Bringing together climate scientists, impact modellers, and economists to build knowledge to effectively deal with climate change“. These are the topics of the papers:
“Network Assessment of the Aviation Climate Impact Considering the European Structured Airspace” by Fateme Baneshi and Manuel Soler
The climate impacts of non-CO2 emissions highly depend on geographical location, altitude, and time of the emissions. Thus, performing more efficient maneuvers to avoid climate hotspots can potentially mitigate their associated climate effects. However, generating a climatically optimal flight plan for each aircraft is not the ultimate solution to this problem when it comes to global traffic scenarios. This is because besides increasing the operating costs as the aircraft fly longer routes, the climate-optimal trajectories also alter the traffic pattern by increasing the congestion around climate hotspots. Therefore, the evolution toward an environmentally friendly trajectory planning framework required a holistic perspective on the consequences of adopting climate-optimal routes at the network scale. In this study, we explored the effects of adopting climate optimized trajectories on ATM performance in terms of complexity, demand, and the number of conflicts.
“Cost-Effective Climate-Friendly Aircraft Flight Planning” by Abolfazl Simorgh and Manuel Soler
When planning aircraft trajectories to reduce climate effects, we need to accept higher operating costs (a trade-off exists). This is because the aircraft flies longer routes to avoid some climate-sensitive areas. For the abstract submitted to EGU, we propose a methodology capable of determining aircraft trajectory with the highest possible climate impact mitigation potential while respecting a user-specified limit on the increased operating cost and vice versa. Besides, the trajectory of aircraft is determined such that the range of the estimated climate effects and the associated uncertainty lie within the user-specified ranges.”
