Meteorology in aviation
current developments and future trends
Digital Sky and Beyond - future downstream services – ESA workshop 18 May 2018, ESTEC

KNMI
- provide meteo data for national airport
- long history of providing (certain) satellite services for aviation
- looking to expand/develop satellite services for aviation à rapid expansion of satellite remote sensing capacity over last 15+ years
- use aircraft as flying sensors for improving weather forecasting (mode-S)

aircraft routing à meteorological data à weather forecasts à satellites
Current developments
- monitoring volcanic ash, smoke, dust- research into specific aspects of severe weather
Trends (data !!!)
- monitoring severe weather & hazards- use meteo data for strategic and tactical flight planning- real time flight guidance- improving weather forecasting (1-10 days)- improving nowcasting of weather (forecasts updated every hour)- first lightening sat missions (global network by 20-something)

but this is key:
enabling access to meteo data
(in a clever way)

Trend: 5G comes with a promise of moving high data volumes at high speed and the interconnection of millions of sensors.
[1] In the meteorological application for aviation, how is the need for real time data evolving?
[2] Is there a trend towards using big data & AI?
[3]how much data, how much needed transmission to be processed on board a/c?
[4] What would be a breakthrough compared with today’s approach to deliver meteo info to the pilots during flight?

[1] In the meteorological application for aviation, how is the need for real time data evolving?
- future aviation = data driven- autonomous flight (requires real-time data on board à high data volume)- tactical/strategic pre-flight planning (can be don on ground and then transferred to aircraft à low data volume)- don’t forget ground logistics, where meteo is also important

[2] Is there a trend towards using big data & AI?
- trend is to exploring full range of data (huge data volumes)
- AI will find its way
- current use of meteo data in aviation is “1960’ish…’, especially on board

[3]how much data, how much needed transmission to be processed on board a/c?
- the more, the merrier
- difficult to estimate: meteo data volumes (obs, models) is rapidly growing
- applications and services that condense data volumes still must be developed
- several Mb to 1 Gb/hour (better gueswork; highly uncertain, depends on how clever the information is packaged, etc…)

[4] What would be a breakthrough compared with today’s approach to deliver meteo info to the pilots during flight?
- real time access to data
- methods/algorithms to handle data and translate data to meaningful information/options/advice/recommendations
- on board capacity to incorporate data in tactical and strategic flight planning
