What is the minimum width of an unpaved runway for basic utility?

The minimum width of an unpaved runway designated for basic utility roles is indeed 50 feet. This standard is established to ensure that the runway can accommodate a range of small aircraft, which are often used for utility purposes such as crop spraying, firefighting, and general aviation support in rural or underserved areas.

A runway width of 50 feet is considered sufficient to provide adequate safety margins for operations while still being manageable for smaller aircraft. It allows pilots to have enough room to maneuver during takeoff and landing, which is essential for operational safety, particularly in unpaved conditions where factors like loose soil or uneven surfaces can impact performance.

In contrast, greater widths may be designated for larger aircraft or special operations, but for the basic utility category, 50 feet is the established minimum, ensuring compliance with regulatory standards while facilitating efficient use of the runway for its intended purposes.
