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

The minimum width of an unpaved runway for general utility is indeed 100 feet. This standard is established to ensure safety and operational efficiency for aircraft using the runway. A runway of this width provides sufficient space for the maneuvering of various types of general utility aircraft, accommodating their wingspan and the potential need for lateral movement during takeoff and landing.

An unpaved runway needs to support diverse operations, including those of smaller aircraft that may require more lateral clearance for safety reasons. The width also contributes to the overall stability of operations in various weather conditions, helping to prevent overruns or accidents.

Wider runways can enhance the operating margins, particularly for general aviation flights, but 100 feet is recognized as the minimum necessary dimension to maintain safe operational practices for a broad category of flying activities.
