Which distance between runway centerlines allows multiple runway crossings to be issued with a single clearance?

When deciding if one clearance can cover crossing more than one runway, the key factor is how close the parallel runway centerlines are. If the centerlines are 1,300 feet apart or closer, a controller can issue a single clearance that authorizes crossing both runways. This keeps instructions clear and reduces the need for multiple separate clearances in tight configurations, which helps maintain smooth flow and reduce miscommunication. Larger separations, like 2,000 feet or 3,000 feet, are beyond the threshold and would require separate clearances for each crossing to ensure pilots have unambiguous instructions for each runway. While smaller distances such as 1,000 feet or less also satisfy the rule, the maximum distance that still allows a single clearance is 1,300 feet, so that choice best reflects the standard practice.
