Effects of weather condition on aircraft emissions in climb phase: Selex Galileo & dia trieste

In order to assess the effect of meteorological data on aircraft emissions, some results have been presented. The accuracy of forecasts for selected weather data was analyzed, the result is that for radar reflectivity and wind forecasts, the accuracy of predictions older than 1 h is low. Radar reflectivity and wind can influence the choice of the pilot in terms of trajectory and consequently emission productions. Therefore, it is very important to use up-to-date information in order to compute a green (low emission) trajectory. The effects of changes of temperature, pressure, relative humidity and wind on aircraft emissions have been analyzed. In order to reduce emissions, it would be useful to have an on-board tool performing trajectory optimization using updated weather information provided by weather radar or other weather information sources.
