STAY AHEAD OF THE WEATHER WITH ACCURATE ONBOARD DATA

This Solution was formerly part of PJ.18-04c-W1

Improved understanding and prediction of weather conditions contributes to enhanced flight safety and efficiency. In addition to information from on-board sensors, pilots receive updates in various formats via datalink including simple text messages, graphical products and satellite images. These inputs cover different timeframes, ranging from past observations to predictions for the next several hours. It falls to the pilot to organise and geo-reference this data, and temporarily build a mental picture as fast as possible. SESAR is examining novel and robust ways to support intelligent data pre-processing, smart filtering and integration, both on ground and on board the aircraft for the two-way exchange of meteorological data.

Moving to SWIM based technology will enable standardised exchange of information. One aspect of this solution is the definition and design of purple profile SWIM services for meteorological data, which so far has no specification. The research is contributing to EUROCAE WG-76 and RTCA SC-206 MET datalink standardisation, and ICAO is also developing standards for turbulence and space weather which could be downlinked or uplinked via a SWIM purple profile service.

While up until now SESAR research primarily addressed on-board meteorological services, the focus now is on external inputs and intelligent pre-processing and integration of incoming data to foster accurate interpretation of the provided content.
