![]() The River Thames varies in depth of water between Cricklade and Teddington. Remember that river levels fluctuate and these distances will change with the river conditions. This is the distance between the standard water level and the highest point of the underside of the bridge. The following table gives the headway of bridges over the River Thames. Teddington Lock (to Teddington Boundary Obelisk) Time to next lock downstream at 8 km/h (minutes) It also gives an estimated travel time based on the speed limit of 8 kilometres per hour (approximately 5 miles per hour). The following table lists the distances between locks from Cricklade Bridge downstream to Teddington Lock. The Aeronautical Planning Chart is used for general planning before a flight.If you are planning to boat on the River Thames, you may also find our locks and facilities for boaters page useful. Radio Facility Charts are used for flying from airport to airport. Navigational Plotting Charts have similar uses as does the Trans Atlantic Plotting Chart. Mercator Plotting Charts are used by aircraft navigators for plotting positions etc. Other types of aeronautical charts are illustrated by five small portions of sheets covering parts of the island of Newfoundland. 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.

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 portion reproduced here is from the Kootenay River chart. Its principal use is the same as for the 1:506 880 series but it is designed to serve higher speed aircraft. The 1:1 000 000 series consists of 68 sheets. It is illustrated here by part of the Banff-Bassano sheet and part of the Avalon-Burin sheet. 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.
