A Chicago sectional chart dated December 10, 1964 depicts Roselle Airfield west of O’Hare and Northwest of Mitchell Airport. In 1965, the terminal building on the north side of the apron was built. It was made of brick exterior bearing walls with metal framing in the roof and has a concrete floor.
White space around the chart is filled with map information and the legend, scales, and tables of airport and airspace information. Terrain is color-coded for its elevation and major roads, cities, and bodies of water are shown for visual reference, as well as other identifiable structures (e.g., stadiums and water towers ).
Like the VFR sectional charts that they complement, terminal area charts depict topographic features and other information of interest to aviators flying visually, including major landmarks, terrain elevations, visual navigation routes, ground-based navigation aids, airports, rivers, cities, and airspace boundaries. TACs are more detailed than ...
Traffic operating under VFR must be identified on radar and explicitly cleared into the airspace before they can enter. The airspace is commonly depicted as resembling an "upside-down wedding cake". The innermost ring extends from the surface area around the airport to typically 10,000' MSL. Several outer rings usually surround it with ...
Sectional charts typically cover a total area of about 340x340 miles, printed on both sides of the map. The scale is 1:500,000. VFR terminal area charts are created with a scale and coverage appropriate for the general vicinity of a large airport (1:250,000). They may depict preferred VFR flight routes within areas of congested airspace.
The sectionals are complemented by terminal area charts (TACs) at 1:250,000 scale for the areas around major U.S. airports, and until 2016 by World Aeronautical Charts (WACs) at a scale of 1:1,000,000 for pilots of slower aircraft and aircraft at high altitude. [1] Since February 2021, the charts have been updated on a 56-day publication cycle. [2]
Published VFR routes are for transitioning around, under, or through some complex airspace. Terms such as VFR flyway, VFR corridor, Class B airspace VFR transition route, and terminal area VFR route have been applied to such routes. These routes are generally found on VFR terminal area planning charts. [14]
According to ICAO, airport diagrams shall show coordinates, field elevations, runways, aprons, taxiways, hot spots, taxiway routes, air transit routes, lighting, air traffic control (ATC) service boundary, communication channels, obstacles, slope angles, buildings and service areas, VOR checkpoints, and movement area permanently unsuitable for aircraft.
