within the areas covered by TACs and VTCs, full details of airspace may not be shown.Where space permits, the route designator, distance and LSALT may also be shown air route information within these areas will usually only include the route line and bearing.within the areas covered by TACs, full details of air routes may not be shown due to lack of space.These areas impact on the ERC-L presentation as follows: ERCs-L show an outline of the areas covered by TACs and VTCs. VTCs are intended for use up to and including FL180.ĮRCs-L, ERCs-H and TACs are presented at various scales and depict airspace, air routes and radio navigation facilities.ĮRCs-L are intended for use primarily up to and including FL200. They contain some topographical detail and appropriate airspace, radio communication and navigation aid information. Visual Terminal Charts (VTCs) (scale 1:250,000) are designed for visual operations near terminal areas. Map coverage is shown on the front of each map.
They contain an aeronautical overlay of controlled airspace over a topographical base, and contain some radio communication and other navigational data appropriate for visual navigation. Visual Navigation Charts (VNCs) (scale 1:500,000) are designed for VFR operations. Australian coverage is shown on the front of each chart. They are constructed on Lambert’s Conformal Conic Projection. World Aeronautical Charts (WACs) (scale 1:1,000,000) are designed for pre-flight planning and pilotage. estimated FIS VHF coverage at 5000 ft and 10,000 ft and.
