What code PLT281 covers, why the FAA tests it, and how to study Chart Supplement U.S. before your checkride.

Official FAA learning statement

Recall information in a Chart Supplements U.S

What this means for your checkride

The Chart Supplement U.S., formerly the Airport/Facility Directory, is a regional listing of airports, seaplane bases, and heliports with their operational data. You look up an airport to read details such as runway surface, runway slope and direction of slope, lighting, frequencies, and services. It is the reference for airport specifics that do not fit on the sectional.

Pulling runway, frequency, and services data from the Chart Supplement is basic preflight planning for any destination.

The common trap

Assuming the sectional shows everything about an airport, when details like runway slope and services live in the Chart Supplement.

Before your checkride (14 CFR 61.39)

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.
