Airline Finance by Peter Morrell
Needs more a) asset price history, and b) secondary markets. Adding technology trends and unit economics would be great; while those topics are not directly "finance", they help finance guys understand how money is and will be earned.
A good rule is to keep writing until the book looks like Stopford's Maritime Economics. Since this was the 2007 edition, presumably the later additions have expanded coverage.
France and Germany will support 95 per cent and the UK 100 per cent of the aircraft cost (less a down-payment made by the airline, or with a commercial bank loan, of 15 per cent). The maximum term is 10-12 years at fi xed interest rates of 120-175 basis points above the 10-year government bond yields. The terms and rates are laid down in the Large Aircraft Sector Understanding (LASU), an agreement between aircraft exporting countries to prevent unfair competition. The 12-year maximum term is considered much too short, especially for large high cost jets such as Boeing 747s, but discussions between the US and European ECAs aimed at extending this limit have not in the past been successful. There is also an agreement between the European ECAs and Ex-Im not to support aircraft sold to airlines in each others territory (although operating lessors could benef i t since the aircraft would not necessarily be operated there).
