Interactive Sectional Chart Training

Most chart training makes you memorise a legend. Here the real FAA sectional is the classroom — you pan it, tap it, slice it and use it to make pilot and drone-operator decisions.

Start Level 1Open the Sectional Lab
SEE IT
Real FAA sectional imagery — not a cartoon of one.
TOUCH IT
Pan, zoom, tap, measure and slice the chart itself.
DECODE IT
Every symbol and number, explained where it's printed.

KSLE — Salem

That's the real printed data block from the current Seattle Sectional. Tap it apart with the Airport Exploder — every airport in the country reads the same way.

Signature tools

Built on the chart, not beside it

Airport Exploder

Tap an airport and its printed data flies apart — each piece tied back to exactly where it's printed.

3D Airspace

Turn flat Class B lines into the stacked shelves they really are — top, side and 3D views from real FAA values.

Airspace Slice

Draw a line across airspace and get a true vertical cross-section with real terrain underneath.

Chart X-Ray

Dim everything except airspace, airports, obstacles, NAVAIDs or terrain. Learn to filter the chart.

Obstacle Inspector

MSL on top, AGL in parentheses — standing on real terrain. Built for pilots and drone operators.

Legend Mode

The chart's own printed legend, made interactive — then find a live example on the chart face.
