CPL Flight Performance and Planning

Expect standalone multiple-choice questions. Each item carries its own data, such as a mass and balance table, a runway chart, or a fuel log, so there are no shared exhibits to flip between. Bring a calculator approved by your authority, and practise extracting only the figures you need from a page of numbers.

The official aviation authority sets the time allowed and the passing mark, and both can change between sittings. Check the authority's own website or your approved training organisation for the current figure rather than relying on what other candidates report. Plan your pace around the published time once you have confirmed it.

Most candidates find the concepts straightforward but the execution demanding. The difficulty lies in unit conversions, interpolating between chart lines, and avoiding a single arithmetic slip that invalidates an otherwise correct method. Steady practice with real flight manual data builds both speed and accuracy far more effectively than rereading theory.

Retake rules, waiting periods, and any limit on the number of attempts are set by the licensing authority, not by training providers. Consult the authority's published examination policy for the current position, and speak to your flight school about additional ground instruction before you rebook, since a second attempt usually exposes the same weak area.

Start with aerodynamics and performance fundamentals, then mass and balance, because centre of gravity and structural limits underpin everything that follows. Move to takeoff and landing, then climb, cruise, and descent. Finish with route and fuel planning and in-flight replanning, which combine the earlier topics into full-flight scenarios.

Common failure modes are misreading units, using the wrong chart axis, forgetting to apply a correction for wind, temperature, or runway slope, and mixing pressure altitude with density altitude. Another frequent error is answering the question asked with a figure that is correct but for a different phase of flight. Write the given values down before calculating.

No. You need to understand how the variables interact so you can read unfamiliar charts confidently. Examiners use data presented in different layouts, and memorising one manufacturer's format leaves you stranded. Learn the underlying relationships, then rehearse interpolation and correction techniques on several different aircraft types.

The arithmetic is simple: multiplication, division, ratios, and percentages. The challenge is doing it accurately under time pressure with mixed units such as feet, metres, pounds, kilograms, litres, and gallons. Practise converting between them until it is second nature, and always sanity-check whether an answer is physically plausible before selecting it.

No. This page is independent study material and is not connected to any aviation authority, examination board, or training organisation. Always treat your licensing authority's current syllabus and your aircraft flight manual as the authoritative sources, and use practice material only to reinforce what those documents specify.
