The portions of the maps appearing on this plate illustrate the kinds of aeronautical charts that were prepared by the Surveys and Mapping Branch of the Department of Mines and Technical Surveys [now Natural Resources Canada] as of 1956. The series of Aeronautical Charts on a scale of 1:506 880 (8 miles to 1 inch) consists of 221 maps principally used for visual reference flying while assisted by aeronautical aids. It is illustrated here by part of the Banff-Bassano sheet and part of the Avalon-Burin sheet. The 1:1 000 000 series consists of 68 sheets. Its principal use is the same as for the 1:506 880 series but it is designed to serve higher speed aircraft. The portion reproduced here is from the Kootenay River chart. The Calgary Instrument Approach Chart and Landing Chart are examples of a series of about 90 maps which form an integral part of the Canada Air Pilot. The Approach Chart is mainly used to descend, by instruments, through cloud, until visual reference to the ground is established immediately before a landing is made. The Landing Chart is used to identify and then land on the runway in use and to show the taxi-ways leading to passenger terminals, hangars and other areas. Other types of aeronautical charts are illustrated by five small portions of sheets covering parts of the island of Newfoundland. Mercator Plotting Charts are used by aircraft navigators for plotting positions etc. Navigational Plotting Charts have similar uses as does the Trans Atlantic Plotting Chart. Radio Facility Charts are used for flying from airport to airport. The Aeronautical Planning Chart is used for general planning before a flight.
