Aviation Investment uniquely addresses investment appraisal methods across the key industries that make up the aviation sector, including the airports, air traffic management, airline and aircraft manufacturing – or aeronautic – industries. This practice-oriented book presents methods through realistic case studies. It covers both economic appraisal, or cost-benefit analysis, measuring the value of projects to society, and financial appraisal, valuing projects as cash generators. This substantially expanded second edition covers in greater detail the treatment of environmental emissions, paying particular attention to climate change. It addresses the treatment of Market-Based Mechanisms (MBMs), including cap and trade systems like ETS and offset systems like CORSIA, and compares them to environmental taxes. It also addresses the adjustments needed to measure the foreign exchange generating value of projects, relevant in the presence of trade barriers. The new edition includes two new project types. One is airport relocations, perhaps the most complex type of airport projects, where the economic case is often more nuanced than may be apparent. The second is the re-introduction of supersonic travel. Aviation Investment offers all aviation sub-sectors a single-source reference, bringing together the theoretical background of the economic appraisal literature and aviation investment in practice. It is written in a style that is accessible to non-academic professionals, using formulae only where strictly necessary to enable practical applications, and benefits from the substantial practical experience of the author.
