EUROCONTROL's INVENTAIR
ENVISA was mandated by EUROCONTROL to create a website dedicated to global aircraft emissions. The site will allow registered users to download and visualise worldwide emission grids based on WISDOM flight movement database.
Environmental Impact Assessment of CDA

Continuous Descent Approach (CDA) procedures have recently been designed and implemented at several European airports to optimise the initial approach phase by removing unnecessary segments of level flight below 6,000 feet.
ENVISA produced environmental impact assessments of CDA trials at Manchester, Bucharest and Stockholm airports, using Flight Data Recorder (FDR) data collected from three partner airlines. Noise, fuel burn and emissions of CDA procedures were compared to those of standard approaches for the same aircraft types.
For each airport ENVISA’s main tasks were to:
- collect and process flight data
- run noise and emission simulations
- perform noise vs. emission trade-off analyses for both standard and CDA procedures.
Outcomes of the studies were presented during the Aircraft & Airport Noise Control session of the 2006 Inter-Noise Congress (Honolulu, US).
