Book excerpt: The second edition of Derek Piggott's introduction to meteorology for glider and light aeroplane pilots. Understanding Flying Weather explains in simple and accessible terms how atmospheric phenomena can be used to improve flying performance and to make flying both economical and enjoyable. Taking into account advances in satellite and computer technology, Understanding Flying Weather describes pressure patterns, cloud formation and how soaring conditions can be used to advantage, as well as detailing the effects of depressions, anti-cyclones and local topography. Its uncomplicated text and diagrams cover the syllabus for the British Gliding Association Bronze 'C' Certificate and so will be particularly relevant to those studying for this important examination. This is the second edition, first published in 2004.
