If you are planning on flying from the channel coast to Sywell you will either need this map, or the 1:500,000 Southern England and Wales chart Edition 36 published 11 March 2010.
Warning Do NOT rely on older editions of either of these maps to navigate from the channel to Sywell as there are some new features exactly on the route such as a new Transponder Mandatory Zone (TMZ) around Stansted CTR.These maps may be obtained by mail order from retailers such as Pooleys or Transair
UK CAA publish a useful VFR guide for pilots not familiar with UK maps and VFR procedures.
The map looks like this, here overlaid with blue lines of latitude and longitude.
A zip file containing a .tif of the map in the championship area and a .map file calibrating it in oziexplorer is available from this page on the on-site intranet.
