Reading Sectional Charts
Sectional aeronautical charts show airspace boundaries, obstacles, and airport information. Understanding these charts is essential for Part 107 certification and safe drone operations.
Airspace Depictions
Different colors and patterns indicate airspace classes. Blue dashed lines show Class D. Magenta shows Class E to the surface. Blue solid circles indicate Class B shelves with altitude labels.
Airport Symbols
Airport symbols vary by type and services. Blue indicates towered airports. Magenta shows non-towered fields. Runway orientation and length appear near each symbol.
Obstacles and Hazards
Towers and obstacles show with height above ground level. Group obstacles indicate multiple structures. Maximum elevation figures help identify highest terrain in each quadrant.
Using Charts for Missions
Check charts before every flight. Identify nearby airspace boundaries. Note obstacles within your operating area. Verify you’re outside controlled airspace or have proper authorization.
