Protection against atmospheric hazards begins with the preparation of the flight, based on medium term (1 h to 12 h) forecast along the route, i.e. at the large scale for a transcontinental flight.
During the flight, alternative decisions require short-term predictions on a limited area along the flight path.
In the airport terminal area, information is needed on a much finer scale and shorter terms.

To improve the accuracy of warnings provided to aircraft in flight, two approaches must be developed:

1.Make warnings specific to small volumes of airspace and small time periods by uplinking dedicated processed products to individual aircraft, and

2.Develop specialised tools for generating nowcasts of these hazards, which will improve accuracy within each airspace volume. The tools are the Weather Information Management Systems (WIMSs).

Due to the processing delay of ground based systems, only on-board weather sensors and functions are usable for very short term forecasts.
FLYSAFE also works on improving those airborne sensors.
