Work Package 4

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
