PLT484: Chart Symbols
What code PLT484 covers, why the FAA tests it, and how to study Chart Symbols before your checkride.
Recall symbols - chart / navigation
What this means for your checkride
Aeronautical chart symbols encode a great deal of information: airport types and services, airspace boundaries and classes, navaids, obstructions with their heights, terrain and elevation by color and contour, and special-use areas. The chart legend defines every symbol, and reading them fluently is core to VFR navigation.
Every VFR flight depends on reading chart symbols, so the FAA tests interpreting airport, airspace, navaid, and obstruction symbology from the legend.
Pilots guess at unfamiliar symbols. The sectional legend defines each one; an obstruction's bold number is height above sea level (MSL) and the number in parentheses is height above ground (AGL).
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.
