Problem Statement: A new airport is being designed at an elevation of 3,000 feet above MSL. The critical design aircraft requires a basic runway length of 6,000 feet under standard sea level conditions. The Airport Reference Temperature (ART) is 25.0°C. The proposed runway has an effective gradient of 0.5%.

Calculate the final actual design length ($L_{actual}$) required for this runway. Apply the standard FAA corrections sequentially.

Problem Statement: An aircraft requires a basic runway length of 6,000 ft at standard sea-level conditions. The proposed airport is located at an elevation of 3,000 ft. Applying the standard FAA elevation correction (increase length by 7% per 1,000 ft of elevation), calculate the corrected runway length.
