About this exam

Meteorology is one of the core theoretical knowledge subjects a candidate must pass before, or alongside, the issue of a Commercial Pilot Licence. The subject exists to prove that you can read a weather picture, predict how it will change while you are airborne, and make operational decisions - diversion, alternate selection, icing avoidance, crosswind limits - from information rather than guesswork. It is aimed at student and licence-aspiring pilots in integrated or modular training who have already covered basic principles of flight and navigation and are ready to apply them to real weather.

The examination is delivered in multiple-choice format and samples the whole breadth of the syllabus: atmospheric structure and the standard atmosphere, the temperature/pressure/density chain and its effect on performance, moisture and stability, cloud and precipitation, fog and visibility, air masses and fronts, pressure systems and synoptic charts, wind from surface to upper levels including shear and turbulence, thunderstorms and other hazards, icing, mountain waves and cold-weather problems, tropical systems, and the interpretation of reports, forecasts and in-flight services. Expect questions that combine a chart or a set of reported values with a decision, not just definitions.

Preparation works best in layers: build the physics first (why air rises, cools and saturates), then learn to read METAR, TAF, significant weather charts and upper-wind data fluently, then rehearse the hazard scenarios. The current question count, time allowance, pass mark, fee and retake rules are published by the licensing authority - check its official site rather than relying on second-hand figures.

What you'll study

Common questions

About CPL Meteorology preparation

What format is the meteorology examination?

It is a multiple-choice paper delivered at an approved examination centre, sat on a computer in most authorities. Each item has one correct answer and several distractors, and some items are built around a chart, a METAR/TAF extract or a table of values embedded in the question text. Confirm the current delivery method with the licensing authority.

How difficult is it compared with other CPL subjects?

Most candidates find the physics comfortable but the applied interpretation demanding. The difficulty is not memorising definitions; it is reading a synoptic chart or a forecast and reasoning about what happens next. Those who practise decoding real reports daily usually find the exam predictable rather than hard.

How long is the exam and how many questions are there?

The licensing authority sets and publishes the current question count and time allowance, and these change from time to time, so check its official website for the figures that apply to your sitting. Do not plan your pacing around numbers quoted in forums or older training material.

What pass mark do I need, and can I retake?

Both the pass standard and the retake rules are set by the licensing authority and are published on its site; they are not fixed across authorities or over time. Check the current notice before you book, and note that some authorities limit the number of attempts or require additional training between them.

In what order should I study the topics?

Start with atmospheric structure, then temperature, pressure, density and stability, because everything later depends on them. Add moisture, cloud and fog, then air masses and fronts, then pressure systems and chart reading. Finish with wind, thunderstorms, icing and tropical systems, and keep reports and forecasts running in parallel throughout.

How much time should I allow for preparation?

Allow enough to cover the syllabus twice: once to learn it and once to test yourself under time pressure. A common pattern is several weeks of steady study alongside flight training, with the last week spent entirely on timed practice and on decoding current METARs, TAFs and charts until it becomes automatic.

Where do candidates most often lose marks?

Three areas recur: confusing stability with lapse-rate arithmetic, misreading the direction of movement and the sequence of weather across a front, and failing to convert between pressure, density and performance correctly. A fourth is careless chart reading - mistaking a trough for a ridge or missing the valid time on a forecast.

Should I memorise METAR and TAF codes?

Yes, but as a reading skill rather than a list. Learn the groups in the order they appear, then practise on live aerodrome reports until you can extract wind, visibility, weather, cloud and temperature in seconds. In the exam you will often need only two or three groups to eliminate the wrong options.

Can I use a calculator or reference material in the exam?

Most authorities provide an on-screen calculator or allow a basic one, and some supply extracts of codes and conversion tables. Rules differ, so check the candidate instructions issued with your booking. Assume you must know the standard formulas and the meaning of chart symbols from memory.

Does this page or site represent the licensing authority?

No. This is independent study material and is not affiliated with, endorsed by, or connected to any licensing authority, examination board or training organisation. Always treat the authority's own published syllabus, notices and candidate instructions as the authoritative source for rules and logistics.
