Aviation meteorology from the ISA to a decoded SIGMET — 1,527 questions across 45 chapters, including the Indian climatology and the decoding practice the DGCA paper leans on hardest.
The paper
Meteorology is a 50-question, 2-marks-a-question paper. Decoding questions — METAR, TAF, SIGMET, station models — are the cheapest marks on it, because unlike the theory they are a skill you can make automatic in a week.
What's inside
Every question is auto-graded, tagged with the chapter it came from and marked Theory or Numerical. Wrong answers are filed in your mistakes bank automatically, per subject.
Composition and structure of the atmosphere, the ISA and its lapse rates, temperature, pressure and density and how they interact, pressure systems, and the altimetry chain — QNH, QFE, QNE, transition altitude and the errors that come with each.
Humidity and dew point, adiabatic processes and atmospheric stability, cloud classification and formation, precipitation, fog and the visibility questions, plus the optical phenomena the paper likes to ask about.
The pressure gradient, geostrophic and gradient wind, surface friction and veering, land and sea breezes, mountain waves, the general circulation, upper winds, jet streams and clear air turbulence.
Thunderstorm structure, life cycle and the hazards each stage carries, airframe and engine icing and where it forms, air masses, fronts and depressions, and the windshear and microburst questions.
The southwest and northeast monsoon, western disturbances, the climatology of the Indian subcontinent season by season, tropical revolving storms, global climatic zones and the world area forecast system.
Reading a METAR and a SPECI, a TAF, a SIGMET and a station model plot, plus the meteorological services chain — briefings, documentation, the forecasts you are entitled to and what each one is actually valid for.
Cross-topic revision sets and full-length practice papers drawn from the whole subject — the sittings that check whether the individual chapters have actually joined up.
Before you start
DGCA meteorology questions rarely stop at a definition. They ask what a condition produces — what stability does to turbulence, what a temperature inversion does to visibility, what a cold front does to your cruise.
Learning the mechanism therefore covers far more of the paper than learning the vocabulary does.
The monsoon, western disturbances and tropical revolving storms carry their own chapters, because a paper written for Indian candidates asks about them properly and most general aviation-weather material does not.
Decoding gets the same treatment: METAR, TAF, SIGMET and station model each get their own drill rather than one shared "codes" chapter.
The single most reliable source of lost marks is ISA arithmetic done in a hurry — 1.98°C per 1,000 ft rounded badly, the tropopause value misremembered, or a deviation applied with the wrong sign.
It is a five-minute fix and it recurs across altimetry, performance and even navigation, so it is worth being the first thing you make automatic.
Run a short decoding set most days — it is a motor skill and it fades without use. Take the theory chapters more slowly, one system at a time, with practice mode showing the reasoning as you go.
Then sit the full 50-question paper on the clock. Two hours for 50 questions feels generous until the decoding is slow.
Inside a question
Every MCQ is graded the moment you answer it, and the explanation shows the reasoning rather than just the correct letter.
Pick an option and get instant right or wrong with the correct answer revealed — except in exam mode, which reveals nothing until you submit.
Numericals carry the governing equation on its own line, so you can revise by formula before you revise by question.
Worked step by step from the given data to the answer, with nothing skipped.
Every question carries its chapter and whether it is theory or a numerical, so a wrong answer tells you what to revise.
