When should the ALP be updated?

• A. 2-7 Years Depending on the Size of the Airport
• B. Every 5 Years Regardless of Size
• C. Every 10 Years
• D. Whenever a New Runway is Added

Answer: (A)

Updating the Airport Layout Plan is about keeping a living map of current facilities and future development that lines up with actual changes at the airport. Because larger, busier airports undergo more frequent developments and have more complex planning needs, they require updates more often, while smaller airports can go longer between updates. That’s why the schedule is not fixed to one number for every airport; it ranges from a couple of years up to about seven years, depending on airport size and activity.

An update is appropriate not only when a new runway is added but whenever significant changes affect the layout, safety zones, or facility planning, such as extensions to taxiways, new apron needs, or changes in future development plans. The key idea is that the ALP must stay current with conditions and planned work, hence a size- and activity-driven update interval rather than a universal fixed period.
