The largest portion of the investment need at large, medium, and small airports is for terminal buildings and ranges from 30% to nearly 50% of total needs. Similarly, the FAA routinely publishes National Plan of Integrated Airport Systems (NPIAS) reports of anticipated development activities determined by surveying nationwide capital improvement plans. The NPIAS reports show that the needs for various types of airport development projects continue to increase. Since 2019, forecasts for airport needs to expand or rehabilitate terminal buildings ballooned by 62%, pavement reconstruction needs increased by 28%, and capacity-related development needs rose by 31%.
Specifcally, capital needs for terminal buildings grew from nearly $4.1 billion to more than $6.6 billion, capacity projects rose from $3.1 billion to around $4.1 billion, and reconstruction projects increased from around $13.1 billion to nearly $16.9 billion.12 Fortunately, the condition of runways continues to be consistent. The FAA sets system performance goals to ensure that a minimum of 93% of paved runways at NPIAS airports are maintained in excellent, good, or fair condition. In fscal year (FY) 2019, data indicates that 97.9% of runways at NPIAS airports are rated as excellent, good, or fair, including 97.8% of commercial service airport runways. While the portion of NPIAS airports rated as excellent, good, or fair saw a slight increase from 97.8% in FY 2017, commercial service airport runways decreased from 98.2% during the same timeframe. However, both categories remained unchanged from FY 2015 to FY 2017.
