Chart symbols
Read the chart from its legend. The symbols the exam leans on:
Aerodromes
- Drawn as its actual runway pattern: a hard-surfaced (paved) runway.
- Plain circle: soft surface only (turf or gravel).
- Circle with an anchor: a water aerodrome (seaplane base).
Obstacles
- A spike from a dot. Two heights are printed: the bold figure is height above sea level (ASL); the figure in brackets is height above ground (AGL).
- Radiating lines around the symbol mean it is lighted.
Airspace and terrain
- Controlled airspace (for example a Class C terminal area) is edged and tinted blue.
- A blue hatched outline labelled CYR (restricted) or CYA (advisory).
- The big number in a grid square is the maximum elevation figure: the highest terrain or obstacle in that square, feet ASL.
- A dot with a number is a spot elevation, the height of that exact point.
Trap: reading the bracketed obstacle height as feet above sea level. Bold is ASL; brackets are AGL.
Note: every symbol above is read off the VNC/VTA chart legend, a paid NAV CANADA product not included here and not defined in the TC AIM; confirm against the current legend.
