119 Four airports agreed to participate in illustrative case studies demonstrating the methodology described in this handbook to help airports evaluate the potential impacts of climate change. The project team presented example scenarios of specific climate risks faced by each airport using the most recent and localized climate data.

124 Climate Resilience and Benefit–Cost Analysis: A Handbook for Airports Although the presentation did not directly discuss the potential use of inundation maps, the Boston participants suggested that linking such maps to flooding occurrence probabilities could be useful for their own internal illustration purposes. They also thought that a high-level handbook would be useful for upper management.

126 Climate Resilience and Benefit–Cost Analysis: A Handbook for Airports It was assumed that the airport would be developing a benefit–cost study to support an LOI application for an AIP grant to extend its longest runway. The main purpose of the extension would be to prevent the cancellation/rescheduling of flights on days with very high temperatures.42 The life-cycle costs (discounted present value)

Case Study Details 127 to the highly uncertain nature of future climate change, one would have to be careful not to put too much stock in the results from any one analysis. As for the specific analysis, airport representatives correctly noted that there will be payload/range restrictions that would become relevant at much lower temperatures than the very high ones used in the example.

128 Climate Resilience and Benefit–Cost Analysis: A Handbook for Airports Based on estimates from Airbus A320 and Boeing 737-800 aircraft performance charts, Exhibit H-11 shows estimated payload penalties in terms of passengers who would not be able to fly when temperatures breach 100°F or 110°F. It is important to note that these estimates of passenger reductions do not take into account the possibility that an airline might be able to offload cargo, which would reduce the number of passengers affected.
