  1. Space Weather and Wake vortex issues FPAW 2007 Tim Miner Allied Pilots Association

  2. Wake Vortex • FAA defines several categories of aircraft based on weight: • Light • Medium • Heavy (255,000 lbs.) • U.K. defines four categories • Airbus 380 now flying with weight over 1 million pounds.

  3. New interim procedures • N JO 7110.478 • a. EN ROUTE: • 1. Small/large/heavy behind an A380 – 5 miles • 2. When transitioning to terminal airspace – provide a minimum of 10 miles spacing • 3. Include the expression “SUPER”immediately after the aircraft call sign in communications with a • terminal facility about A380 operations, and when issuing traffic advisories regarding an A380. • 4. Visual separation rules specified in FAAO 7110.65, chapter 7, section 2, shall not be applied with • respect to the A380. • b. TERMINAL: • 1. Separate aircraft operating directly behind or directly behind and less than 1,000 feet below by: • NOTE- • Consider parallel runways less than 2,500 feet apart as a single runway because of the possible effects of wake • turbulence. • (a) Heavy behind A380 – 6 miles • (b) Large behind A380 – 8 miles • (c) Small behind A380 – 10 miles • N JO 7110.478 • 2 • (d) When applying wake turbulence separation criteria for terminal operations that are defined in • minutes, add 1 additional minute. • 2. Use the expression “SUPER” immediately after the aircraft call sign in all communications with or • about an A380.

  4. Wake Vortex issues • Dissipation characteristics of a super vortex? • Do we need to sense and track these vortex?

  5. Space Weather • Two main issues for aviation • Operational impacts of energy fluctuations from space • Disruptions to communications • Need to reroute flights to maintain communications • More polar routes place more aircraft in jeopardy • Biological impacts • In Europe, aviation workers given the status of X-ray operators—crews limited to exposure amounts

  6. Impact of Space Weather • SEC now showing potential operational impacts via websites

  7. Impact of Space Weather • Now looking for the 4-D data cube of space weather around the globe to monitor crew exposure to radiation.
