What is the runway surface type at EFTA?

The runway surface type at EFTA is classified as asphalt, which is commonly used for its durability, smoothness, and ability to withstand different weather conditions. Asphalt runways provide a solid foundation that supports the weight of aircraft during takeoff and landing while also offering good friction for tire grip, which is essential for safety.

In contrast, concrete surfaces, while also durable, are often stiffer and can lead to higher maintenance costs due to cracking and wear over time. Grass runways are typically found at smaller airfields or in rural areas and are less suitable for larger aircraft due to their limited structural integrity and susceptibility to weather conditions. Bitumen, while a type of asphalt, refers more to the sticky, black substance used in the paving process rather than the overall surface type, which is specifically identified as asphalt in this context. Thus, identifying EFTA's runway as asphalt accurately reflects its construction and operational characteristics.
