GNC Series
Global Navigational Charts (GNC) is a worldwide series of aeronautical charts produced by NGA. These charts are on a scale of 1:5,000,000 and intended for high- altitude, high- speed, extended long- range navigation and flight planning. The charts show principal towns, drainage, primary roads and railroads, prominent culture, shaded relief, and spot elevations.
GNCs are available in paper or ADRG-derived format.
