Aviation Weather for Dispatch
Dispatchers share legal responsibility for every flight release, which means reading and interpreting aviation weather is not optional background knowledge—it is a core dispatch function tested directly on the ADX exam. From decoding METARs, TAFs, and SIGMETs to understanding how synoptic-scale systems, icing, and convective outlooks affect route planning, this subject spans both meteorological theory and its practical application to go/no-go decisions. Mastery here directly supports the ACS requirement that dispatcher candidates evaluate weather hazards and apply that analysis to real-world operational control scenarios. Work through our 11 in-depth, ACS-aligned aviation weather for dispatch articles below, or return to the Aircraft Dispatcher library.
Decoding METARs and TAFs for Release Weather Decisions
Aircraft dispatchers must accurately interpret METARs and TAFs to authorize flights legally and safely; this article breaks down every element of both reports and explains how dispatchers apply them to release decisions under 14 CFR Part 121.
Reading the Surface Analysis and Surface Prognostic Charts for Dispatch
Surface analysis and prognostic charts are critical dispatch tools that depict current and forecast weather systems, fronts, pressure centers, and isobars — enabling dispatchers to assess en-route and destination conditions before releasing a flight.
Using the Significant Weather (SIGWX) Prog Charts on a Long-Haul Release
Significant Weather Prog Charts (SIGWX) depict forecast areas of hazardous weather at flight levels and are an essential tool dispatchers use to evaluate en-route hazards before releasing a long-haul flight.
SIGMETs, Convective SIGMETs, and AIRMETs: Dispatch Impact and Avoidance
SIGMETs, Convective SIGMETs, and AIRMETs define hazardous weather boundaries that directly govern dispatcher release authority, rerouting decisions, and legal flight-plan validity under 14 CFR Part 121.
Icing Forecasts, FIP and CIP Products, and Anti-Ice Dispatch Considerations
Aircraft dispatchers must understand icing forecast products—including Forecast Icing Products (FIP) and Current Icing Products (CIP)—to legally and safely dispatch flights into known or forecast icing conditions, ensuring aircraft certification and equipment match the threat.
Turbulence Forecasting: GTG, PIREPs, and Ride-Quality Routing
Aircraft dispatchers use Graphical Turbulence Guidance (GTG), pilot reports (PIREPs), and ride-quality routing to keep flights smooth and safe; understanding how each tool works and how to combine them is essential for dispatch decision-making.
Low-Level Wind Shear and Microburst Awareness for Departure Planning
Low-level wind shear and microbursts create sudden, life-threatening performance changes during takeoff and initial climb; dispatchers must recognize hazard indicators and apply avoidance strategies before releasing a flight.
Tropical Cyclone and Hurricane Planning for Affected Station Operations
Tropical cyclones and hurricanes pose extreme hazards to flight operations and station infrastructure; dispatchers must understand storm structure, timing windows, and regulatory responsibilities to protect aircraft, crews, and passengers.
Volcanic Ash Advisories and Rerouting Around VAAC Forecast Areas
Volcanic ash is an acute, invisible hazard capable of destroying jet engines and abrading cockpit windshields in minutes; dispatchers use VAAC advisories and VAAs to reroute flights clear of forecast ash clouds before departure and in-flight.
Ceiling and Visibility Forecasting: RVR, Slant Range, and Approach Minima
Ceiling and visibility forecasting for dispatchers covers RVR, slant-range visibility, and how weather minima are applied to approach categories—critical knowledge for legal dispatch and en-route decision-making.
Winter Operations: Deicing, Holdover Times, and Dispatch Coordination
Winter dispatch requires understanding of aircraft contamination types, deicing/anti-icing procedures, holdover time tables, and the dispatcher's legal role in coordinating ground operations to ensure safe departure.
