Operational Navigation Charts (ONC). ONCs support high speed radar navigation requirements at medium altitudes. Other uses include visual, celestial, and radio navigation. In the absence of Tactical Pilotage Charts, they satisfy DoD requirements for enroute visual and radar navigation in low altitude operations. The sheet size is 42 by 57-1/2 inches covering eight degrees of latitude. (Scale 1:1,000,000)
