A market assessment/feasibility study typically consists of two phases. The market assessment determines if the current level of demand exceeds the current capacity at the airport and in the immediate market area by analyzing general conditions, trends, and demographics. The assessment may also analyze the type or size of proposed improvements that would be required to meet the market demands. The feasibility study ascertains how much capacity the market can support by implementing a best practices approach to estimating the revenue, costs, and expenses (capital and operating) and return-on-investment (ROI) potential associated with the proposed development.
