  1. WIND CONSTRAINTS & OPPORTUNITIES AN AIRLINE OPERATIONS CENTER (AOC) PERSPECTIVE TOM LLOYD MANAGER METEOROLOGY & ROUTE OPTIMIZATION AIR TRAFFIC SYSTEMS

  2. WINDS • Terminal area winds • Runway selection • Operating limitations • Air Traffic Management (ATM) considerations • En route winds • Route selection • Fuel burn calculation

  3. AVAILABLE APPROACHES ILS 15 Minimums 1/2SM RVR 2400 ILS 33 Minimums 1SM RVR 5000

  4. FLEET OPERATIONAL RESTRICTIONS • Varied by fleet type and operator • Tailwind components • Typical max for takeoff/landing = 10 knots • Some fleet types = 15 knots • Short runways / wet runways • Crosswind components • Vary widely; typically 28-38 knots (could be steady or gusting) • Reduced for runway contamination (10-20 knots) or Cat II/III operations (15 knots or less)

  5. ATM CONSIDERATIONS:AIRPORT INTEDERPENDENCY

  6. ATM CONSIDERATIONS: AAR • Airport Acceptance Rate (AAR) • Key number which drives Traffic Management Initiatives (TMI) • Dependent in part on runway configuration • Can be affected by speed over threshold • Higher ground speed (tailwind)  • Longer runway occupancy  • Greater separation required in the pattern  • Reduction in AAR

  7. EN ROUTE / WINDS ALOFT • Route selected using flight planning system • Wind forecasts • GFS output (GRIB format) • Gridpoint forecasts • Interpolation to fixes and FLs

  8. THANK YOU! TOM LLOYD MANAGER METEOROLOGY & ROUTE OPTIMIZATION AIR TRAFFIC SYSTEMS
