Which planning horizon is commonly expressed as twenty years?

• A. 20 years
• B. 15 years
• C. 25 years
• D. 30 years

Answer: (A)

In long‑range airport planning, the horizon defines how far ahead the plan looks. The twenty-year horizon is standard because it aligns with typical capital investment cycles and the forecast window needed for major infrastructure projects. It provides enough time to project demand growth, plan runway and terminal expansions, and sequence investments in a way that can be funded and implemented, while keeping the assumptions manageable. Master plans for airports are commonly built around roughly two decades into the future, with updates every few years to reflect changing conditions. Other horizons exist, but fifteen years is more mid‑term, and thirty or twenty‑five years are longer ranges used in different contexts or for broader strategic thinking. The twenty‑year window best fits the practical needs of facility planning and funding cycles, making it the commonly expressed planning horizon.
