A
municipal bond used to construct or expand an airport. The bond is
secured by the
revenue the airport receives in the course of its operations, or by the revenue from lease payments made by a particular airline. In either case, the
issuing municipality does not back the bond itself. Generally speaking, an airport revenue bond is
riskier than other municipal bonds because airports have no power to tax, and thus a sudden fall in revenue may result in an inability to
repay the bond.
