Maximizing Airline Operations: AOC Perspective on Wind Constraints & Opportunities

Explore the impact of winds on airline operations from an Airline Operations Center (AOC) viewpoint. Delve into topics like runway selection, operational limitations, Air Traffic Management (ATM) considerations, and fuel burn calculation. Understand fleet operational restrictions, ATM interdependency, and en route wind effects. Gain insights into available approaches, fleet types, and airport acceptance rates. Tom Lloyd, Manager of Meteorology & Route Optimization at Air Traffic Systems, shares valuable information.

  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
