System and Method for Merging Meteorological Data Predicted and Measured on an Aircraft
Chaix Philippe,Alex Bourdon,Alexandre Grattard +2 more
- 03 Sep 2009
TL;DR: In this article, the predicted and measured meteorological data are merged together to supply them to the flight prediction calculation system so as to smooth the discontinuities brought about in the prior art by the simple update which is carried out.

System and Method for Calculating Flight Predictions by Vertical Sections
Alexandre Grattard,Nicolas Simi,Alex Bourdon +2 more
- 26 Aug 2009
TL;DR: In this paper, an intermediate prediction horizon is defined between the flight phase and the leg, such that the limit conditions that are applicable to it, for example the target speed, target altitude, characteristic altitude and maximum end-of-section distance, are valid for the entire vertical section.

System and melting process meteorological measured and predicted data on aircraft
Philippe Chaix,Alex Bourdon,Alexandre Grattard +2 more
- 05 Sep 2008
TL;DR: In this paper, the authors proposed a system for calculating flight predictions using linear weighting of the predicted weather data, the weighting coefficient depending on the positioning in the vertical and horizontal distances predicted point / plane in relation selected thresholds.
