Transport Canada Flight Dispatcher Meteorology Exam · Give each week a clear focus.
8 weeks · About 7 hours per week
Thunderstorms, Turbulence, Icing, and Other Aviation Hazards & Moisture, Humidity, Condensation, and Stability
Explain how conditional and convective instability arise from lapse-rate and moisture profiles, and identify which soundings favour thunderstorm development.
Distinguish the four stages of thunderstorm life cycle and list the hazards each stage produces for aircraft operations.
Describe the formation mechanisms of clear-air turbulence, mechanical turbulence, and low-level wind shear, and state the conditions under which each is forecast.
Identify the structural and aerodynamic icing types, the temperature and moisture regimes that produce them, and the severity classification used in aviation reports.
Your checkpoint
A one-page hazard matrix mapping each hazard (thunderstorm, turbulence, icing, wind shear, hail, microburst) to its triggering conditions, associated cloud or frontal setting, and the advisory product that would warn of it, with at least 95% of entries filled from memory before checking notes.
Thunderstorms, Turbulence, Icing, and Other Aviation Hazards & Moisture, Humidity, Condensation, and Stability
Interpret a Skew-T/log-P sounding to locate the freezing level, the lifted condensation level, and the equilibrium level, and infer the convective available potential energy qualitatively.
Explain the difference between stable, unstable, and conditionally unstable layers and predict the cloud types each would produce.
Describe how supercell and multicell organisation differs and what that implies for hail, tornado, and downburst risk.
Summarise the conditions that produce freezing rain and freezing drizzle in a frontal setting and explain the threat to aircraft on approach.
Your checkpoint
A written 300-word case analysis of a hypothetical sounding (temperature and dewpoint values provided in the exercise) that names the stability regime, predicts cloud types and icing risk, and states whether a SIGMET for thunderstorms would be justified.
Air Masses, Fronts, and Frontal Weather & Mid-Latitude Cyclones and Synoptic-Scale Weather Systems
Contrast the structure and weather of cold, warm, stationary, and occluded fronts, including slope, speed of movement, and typical cloud sequences.
Explain the life cycle of a mid-latitude wave cyclone from cyclogenesis through occlusion and dissipation, and locate the associated jet-stream features.
Identify the air-mass source regions affecting North America and describe the weather each brings when advected over the dispatcher's operating area.
Describe how upper-air troughs, ridges, and vorticity maxima relate to surface cyclogenesis and intensification.
Your checkpoint
A hand-drawn or text-described frontal cyclone diagram annotated with the position of warm, cold, and occluded fronts, the warm and cold sectors, the dry slot, the jet streak, and the typical weather in each zone, checked against course notes with corrections noted.
Mid-Latitude Cyclones and Synoptic-Scale Weather Systems & Air Masses, Fronts, and Frontal Weather
Interpret 500-hPa and surface analyses to identify a developing low, its forecast track, and the timing of frontal passage at a specific aerodrome.
Explain how blocking patterns, cut-off lows, and rapid cyclogenesis affect forecast confidence and dispatch decisions.
Relate frontal passage to wind shifts, pressure tendency changes, and visibility reductions a dispatcher would monitor.
Describe the role of moisture transport and low-level jets in sustaining precipitation along a frontal boundary.
Your checkpoint
A two-page frontal passage brief for a chosen aerodrome covering expected wind shift time, pressure trend, ceiling and visibility changes, and a stated confidence level, evaluated against the marking rubric with at least three specific corrections recorded.
Meteorological Observations: METAR, SPECI, PIREP, and Upper-Air Data & Forecasts and Advisories: TAF, GFA, SIGMET, AIRMET, and Warning Products
Decode a full METAR and SPECI, including wind, visibility, present weather, cloud layers, temperature and dewpoint, altimeter setting, and remarks.
Decode a TAF into a timeline of expected conditions and identify the change groups, probability groups, and temporary fluctuations.
Explain the purpose and content of PIREPs and upper-air data, and state how each supplements surface observations.
Interpret GFA cloud, weather, and icing panels and relate them to the TAF for the same period.
Your checkpoint
A decoding worksheet of ten METAR/SPECI reports and five TAFs, each fully expanded into plain language with any flight-category classification (VFR/MVFR/IFR/LIFR) assigned, scored at 90% or better against the answer key.
Forecasts and Advisories: TAF, GFA, SIGMET, AIRMET, and Warning Products & Meteorological Observations: METAR, SPECI, PIREP, and Upper-Air Data
Distinguish SIGMET, AIRMET, and warning products by criteria, validity period, and issuing authority, and state when each is required.
Explain the difference between a forecast advisory and an observation-based warning and how each enters a dispatch release.
Describe how to monitor amendments and corrections to TAFs and how to decide when a re-dispatch or alternate is warranted.
Interpret upper-air charts (850, 700, 500 hPa) to extract temperature, wind, and moisture information relevant to icing and turbulence forecasting.
Your checkpoint
A decision log of five simulated weather scenarios, each naming the applicable advisory product, the criteria met, the action a dispatcher would take, and the source document consulted, with every entry justified in one or two sentences.
The Atmosphere: Composition, Structure, and Standard Atmosphere & Temperature, Pressure, Density, and Their Altimeter Implications & Clouds and Precipitation
Describe the composition and vertical structure of the atmosphere and the assumptions of the standard atmosphere, including the standard lapse rate and tropopause height.
Explain the relationships among temperature, pressure, and density and how each affects aircraft performance and true airspeed.
Interpret altimeter settings, pressure altitude, density altitude, and the errors introduced by extreme temperatures and pressures.
Classify clouds by genus and height and match each to the precipitation type and aviation hazard it implies.
Your checkpoint
A one-page altitude and performance reference sheet showing how to compute pressure altitude and density altitude from a given altimeter setting and temperature, with two worked examples and a stated rule of thumb for hot-day and cold-day altimeter errors.
Mountain, Coastal, and Local Weather Effects & Weather Charts and Meteorological Information Services
Explain mountain wave formation, lee-side turbulence, and the indicators a dispatcher uses to anticipate them.
Describe sea-breeze, land-breeze, and valley-wind circulations and their effect on fog, low cloud, and crosswind components.
Identify the principal weather charts, their symbols, and the information services that distribute them, including the role of the meteorological watch office.
Integrate all domains into a single dispatch weather brief for a route crossing a mountain barrier and a coastal zone.
Your checkpoint
A full practice exam under timed conditions plus a one-page integrated route weather brief covering departure, en route, and destination conditions, with a self-scored review listing every missed domain and a remediation action for each.
Milestones
Week 2: Score at least 80% on a self-made 20-question quiz on stability, thunderstorm hazards, and icing, and correctly identify the stability regime and icing threat from a sounding without notes.
Week 4: Correctly annotate a frontal cyclone diagram and produce a frontal passage brief that names the wind shift time within a stated two-hour window and matches the reference analysis on at least four of five elements.
Week 6: Decode ten METARs and five TAFs at 90% accuracy and correctly match five weather scenarios to the required SIGMET, AIRMET, or warning product in every case.
Week 8: Achieve at least 75% on the timed practice exam with no domain below 60%, and submit an integrated route weather brief that addresses all eleven domains at least once.
