Brunei DCA CPL(A) Performance

It is a written, multiple-choice examination on aeroplane performance, sat under the Department of Civil Aviation's supervision. Items are based on performance data and scenarios rather than recall of definitions alone. Confirm the current paper format, item count and permitted reference material with the Department before you apply, as these details are set by the authority.

Those figures are set and published by the Department of Civil Aviation, and they change from time to time. Do not rely on numbers quoted by other candidates. Check the Department's official examination documentation or contact it directly for the current time allowed, pass standard and any mark allocation across the syllabus.

Most candidates find the arithmetic manageable but the interpretation demanding. The difficulty lies in multi-step questions where a single wrong correction - using pressure altitude instead of density altitude, or forgetting wind on the landing distance - changes the answer. Steady practice with worked examples makes it a very passable paper.

Retake arrangements, waiting periods and any limits on the number of attempts are governed by the Department of Civil Aviation. Ask for the current policy before you sit the paper so you know where you stand. Attempt rules are commonly tied to the validity of your other examination passes, so clarify that at the same time.

Start with atmospheric physics and the International Standard Atmosphere, because almost every other calculation depends on pressure altitude, temperature and density altitude. Then move to take-off and landing distance corrections, followed by climb and en-route performance, and finish with flight manual chart interpretation, which draws on everything else.

Mixing pressure altitude with density altitude, applying wind correction in the wrong direction, ignoring runway slope and surface, forgetting to apply mass corrections before reading the chart, and interpolating carelessly between chart lines. Another frequent error is answering the question asked rather than the one you assumed - read the limiting condition carefully before calculating.

No. You need to understand how charts are constructed and how to read them accurately, including the correction blocks and notes. In the examination you work from data provided or from the aeroplane type you are training on. Practise reading real flight manual charts rather than simplified textbook versions.

There is no prescribed figure. Most candidates need several weeks of regular, active practice rather than passive reading. Aim for short sessions of worked calculations, then full-length timed practice once your accuracy is consistent. Track which correction steps you get wrong and revisit those specifically.

No. The written examination is one element. The licence also requires flight training and a practical skills test in which performance planning is assessed. Confirm the complete requirement set, including any prerequisites, with the Department of Civil Aviation and your approved training organisation.

Only from the Department of Civil Aviation itself. Its website and examination office publish sitting dates, fees, venues and administrative requirements. Your flying school can guide you through the application, but the Department's published information is the authoritative source for anything to do with sitting the paper.
