Natural hazards and weather risk management: what’s new?
Network WX Resilience
2EUROCONTROL Operational Safety 2
One can’t do anything about the weather! ?
US NTSB – over 20% of the aviation accidents
More than 20% of the airport delays
Boeing survey – the highest training concern
Two thirds of the wx delays are avoidable (FAA)?

….But it is a complex stuff….

Meta data shows the “Start Time” which might be renamed “time of occurrence”.
The data also lists the “End Time”, which defines the latest time at which the Natural Hazard will be shown in the HMI (default 24 hours after occurrence)End = 2013-11-20T08:00:00Z
Natural Hazard: Chemical dispersion
11Top 5 Safety Priorities 11
What do we need from the model
1. SUPPORT FOR CRISIS MANAGEMENT (Article 4 1. (h) 677/2011)
Single Network picture
Consistent impact assessment approach
Anticipating Network-wide impacts
2. MONITORING NETWORK PERFORMANCE (Article 20 1(a) 677/2011)
Calibrate the historical daily delays with the actual impact risk
3. COMMON REFERENCE PLATFORM (Article 4 3. (a) to (c) 677/2011)
Network alerts

Natural Hazards
This is deterministic and observation-based data:
1. Volcanic Ash
2. Nuclear Emissions
3. Hazardous Chemical Dispersion
4. Fire
5. Earthquake
6. Flooding
7. Space Weather
No risk score is calculated, map will indicate the location of the hazard, as defined by the authoritative source

• Data are based on NM previous operational experience
• No validation of the data against the actual operations.
• Both ATC capacity impact data and NM impact data are based on the ANSP decision triggers
• Periodic validation based on data
• Simulations or analytical models for the actual operational conditions
• Continuous validation of the data against the actual operations.
• Reference feedback from ANSP – credible to triger coordination
• NM Network impact data is based on analysis of historical data
• Periodic validation based on judgement supported with data
