Description of work:
T4.1 Traffic sample identification
- Route network analysis
- Selection of the appropriate traffic sample selection
- Providing the traffic area
T4.2 Assessing the persistent contrail prediction skills based on trajectory calculations
- Adapt the trajectory optimization model to incorporate the improved persistent contrails prediction methods
- Calculate 4-D trajectories for sample traffic based on different contrail mitigation strategies.
- Evaluate the persistent contrails prediction skills through the trajectory calculations.
T4.3 Assessing the climate impact reduction potential from avoiding persistent contrails
- Adapt the trajectory optimization model to incorporate the regulatory measures
- Calculate 4-D trajectories for sample traffic via balancing the eco-efficiency between climate impact, e.g., contrail and cost change.
- Calculate cost optimized 4-D trajectories for sample traffic under consideration of algorithmic 4-D cost functions for climate change (Policy driven flight optimization; Input from WP5)
- Identify the effectiveness of both contrail avoidance and policy intervention.
- Assess the climate impact reduction potential from contrail avoidance.
T4.4 Demonstrating the climate impact mitigation by green flights
- Implementation of the optimized trajectories in a state-of-the-art air traffic planning algorithm
