What is a key factor to consider when designing a new airport runway?

When designing a new airport runway, considering the largest aircraft sizes to be accommodated is crucial because runways must be built to support the specific requirements of the aircraft that will use them. Larger aircraft typically require longer runways for takeoff and landing due to their weight and the associated thrust needed to achieve lift. Additionally, they may have specific design requirements related to runway width and surface strength to ensure safety and operational effectiveness.

While other factors like future technological developments, expected air traffic volume, and the number of planned terminals are important in the overall airport design, they do not directly influence the physical dimensions and structural requirements of the runway itself. The runway's ability to support the largest aircraft ensures that the airport can handle a range of operations, including those from larger carriers, without safety or performance issues. Therefore, prioritizing runway design to accommodate the largest aircraft types is vital for ensuring that the airport remains functional and competitive in the aviation market.
