What is the scale of a VNC chart?

The scale of a VNC (VFR Navigation Chart) in Canada is 1:500,000. This means that one unit of measurement on the chart (such as one inch) represents 500,000 of the same unit on the ground. The VNC is specifically designed for visual flight rules (VFR) navigation and provides pilots with the necessary information for navigation while in Canadian airspace.

At this scale, VNC charts can effectively display a broad area while providing sufficient detail for pilots to identify prominent geographical features, airspace boundaries, and navigation aids. This scale strikes a balance between detail and coverage, allowing pilots to navigate effectively without having to switch charts too frequently.

The other scales reflect the design purpose of other types of charts, such as specialized or government use, and are not suitable for the general navigation needs addressed by the VNC. By understanding that the VNC is at a 1:500,000 scale, pilots can better grasp how to interpret the chart and apply this knowledge to their flight planning and navigation tasks.
