Which runways at KNGP are designated for left traffic?

Left traffic patterns are typically established to enhance safety and operational efficiency in the vicinity of an airport by providing standardized flight paths for arriving and departing aircraft. At KNGP, the runways that are designated for left traffic include those that facilitate this traffic flow according to standard operating procedures.

The correct answer lists 13L, 31L, 36, and 4 as having left traffic patterns. Each of these runways aligns with the left traffic configuration, allowing for an effective management of runway use, especially when considering the prevailing winds and geographical layout of the airport.

Understanding which runways are designated for left traffic is crucial for pilots and air traffic controllers as it helps ensure safety during takeoff and landings, prevents potential collisions, and maintains efficient airspace management.
