When ice and/or snow are present, what is the required spacing for taxiing on the centerline?

When ice and/or snow are present on the runway or taxiway, maintaining proper spacing when taxiing is critical for safety and control. The correct spacing requirement for taxiing on the centerline in these conditions is 300 feet. This distance is significant because it provides a safety buffer that helps prevent potential collisions with other aircraft and allows for adequate maneuverability, especially on slippery surfaces.

Given the hazardous conditions that ice and snow create, the additional space can help pilots deal with unexpected slides or loss of traction while taxiing. The standard practice is designed to ensure that even with reduced handling capabilities associated with icy conditions, there is sufficient distance between aircraft to mitigate risks. Other answer choices reflect shorter distances that may not account for the reduced handling capabilities and the increased stopping distances needed in such conditions.
