Transport Canada Flight Dispatcher Meteorology Exam study guide
Transport Canada Flight Dispatcher Meteorology Exam · Work through your exam, one topic at a time.
The Transport Canada Flight Dispatcher Meteorology Examination is a knowledge test that assesses whether a flight dispatcher candidate can interpret and apply meteorological information at the level required for operational control of flights. It is aimed at people preparing for a dispatcher licence or working toward roles in airline flight dispatch, flight following, or flight planning, where weather analysis directly shapes fuel, routing, and go/no-go decisions. The Transport Canada Flight Dispatcher Meteorology Exam study guide has 11 sections and about 2,683 words.
01The Atmosphere: Composition, Structure, and Standard Atmosphere
Candidates should be able to describe the atmosphere as a mixture dominated by nitrogen (about 78% by volume) and oxygen (about 21%), with argon, carbon dioxide, water vapour, and trace gases making up the remainder. Water vapour is highly variable (roughly 0–4% by volume) and matters disproportionately for weather.
334 words, about 2 min02Temperature, Pressure, Density, and Their Altimeter Implications
Understand how temperature, pressure, and density interrelate through the gas law: density falls as pressure falls or temperature rises. Know the pressure altimeter's three settings (QNH, QFE, QNE/standard 1013.25) and what each displays.
270 words, about 1 min03Moisture, Humidity, Condensation, and Stability
Distinguish vapour pressure, mixing ratio, dew point, and relative humidity. Relative humidity depends on temperature; dew point is the temperature to which air must cool to saturate at constant pressure and is a better absolute moisture measure.
262 words, about 1 min04Clouds and Precipitation
Know the ten genera and, more importantly, their aviation significance. Stratiform cloud (stratus, altostratus, nimbostratus) implies stable air, steady precipitation, and layered obscuration; cumuliform cloud (cumulus, cumulonimbus) implies instability, turbulence, icing, and showery precipitation.
249 words, about 1 min05Air Masses, Fronts, and Frontal Weather
Know the air mass source regions and classifications (cP, mP, cT, mT, and their continental/maritime variants) and the weather each brings to Canada. Understand front types: cold, warm, stationary, and occluded (cold and warm occlusion).
260 words, about 1 min06Mid-Latitude Cyclones and Synoptic-Scale Weather Systems
Understand the life cycle of a mid-latitude cyclone: cyclogenesis along a frontal zone, open wave stage, mature stage with occlusion, and decay. Know the roles of upper-level divergence, jet streaks, and trough/ridge patterns in forcing ascent.
233 words, about 1 min07Thunderstorms, Turbulence, Icing, and Other Aviation Hazards
Know thunderstorm types (single cell, multicell, supercell, squall line), the three required ingredients (moisture, instability, lifting mechanism), and the life cycle (cumulus, mature, dissipating). The mature stage brings the greatest hazards: severe turbulence, hail, lightning, microbursts, and wind shear.
235 words, about 1 min08Mountain, Coastal, and Local Weather Effects
Understand orographic lifting and the resulting windward cloud/precipitation and leeward drying (rain shadow). Know mountain wave formation, lenticular clouds, rotor zones, and the associated severe turbulence and downdrafts.
215 words, about 1 min09Meteorological Observations: METAR, SPECI, PIREP, and Upper-Air Data
Be fluent in METAR and SPECI syntax: station identifier, time, wind (direction, speed, gusts, variability), visibility, runway visual range, present weather, sky condition, temperature/dew point, altimeter, and remarks. Know SPECI is issued for significant changes between routine reports.
204 words, about 1 min10Forecasts and Advisories: TAF, GFA, SIGMET, AIRMET, and Warning Products
Understand TAF structure: issue time, validity period, wind, visibility, weather, sky, and change groups (FM, TEMPO, BECMG, PROB). Know the difference between a temporary fluctuation and a becoming condition.
204 words, about 1 min11Weather Charts and Meteorological Information Services
Know the main chart types: surface analysis, upper-air charts (850, 700, 500, 250 hPa), significant weather (SIGWX) charts, and prognostic charts. Understand how to read isobars, contour heights, troughs, ridges, and jet stream positions.
