ICAO requirements for Space Weather – WMO Cg XVI Side Event – 17 May 2011

3. Background
Year 2000: New air trans-polar routes opened up between North America and East Asia
Later: Polar routes across the South Pole
Today: Approx 8000 trans- or cross-polar routes per year (N and S Poles)
Polar trajectories are more cost effective for airlines
Shorter, more direct, long-haul routes
saving fuel and minimising environmental impact
…and more convenient for passengers
Less time in the air

ANC
ICAO MET Divisional Meeting
(2002)
Recommendation 1/20c)
Recognition that aircraft operating on high latitude polar routes could be exposed to hazardous levels of solar radiation that could affect crew and passenger health, communications, navigation and avionics
Recommendation that an assessment be conducted of the need for the provision of information for international air navigation on solar radiation storms and other bio-hazards
