What is the runway surface and strength rating at EFTA?

The correct answer indicates that the runway surface at EFTA is asphalt, with a strength rating of 6. The strength rating is crucial as it informs pilots and aircraft operators about the maximum aircraft weight that the runway can safely support without undergoing significant damage. A strength rating of 6 suggests a good capability for handling a variety of aircraft, including those in the larger classifications typically used for commercial and cargo operations.

Asphalt is a commonly used surface material for runways because it provides good traction and is suitable for a wide range of weather conditions. Its flexibility and durability allow it to withstand the repeated stresses of aircraft landings and takeoffs.

Understanding the specific surface material and its strength rating is essential for flight operations and safety assessments. Operators rely on this information to ensure that the aircraft they intend to operate are compatible with the runway's characteristics, thereby preventing incidents related to runway overload or surface failure.
