PLT289: Weather Depiction Charts
What code PLT289 covers, why the FAA tests it, and how to study Weather Depiction Charts before your checkride.
Recall information on a Weather Depiction Chart
What this means for your checkride
A weather depiction chart, and its modern graphical equivalents, summarizes ceiling and visibility across a region, shading areas of IFR and marginal VFR and plotting simplified station data. It gives a quick big-picture of where the good and bad flying weather is before you dive into the details.
A fast VFR/IFR overview supports the go/no-go, so the FAA tests reading the depicted IFR and MVFR areas and station plots.
Pilots use the depiction chart as the final word on a specific airport. It is a broad-brush overview; you confirm actual conditions with the METAR and TAF for your fields.
Where to study it
A code on your test report is an area of deficiency. An authorized instructor must review it with you and endorse that review before you take the practical test, and the examiner may revisit it during the oral. Study it until you can explain it out loud, not just recognize the answer.
