Clearance to cross multiple runways can only be issued when the taxi distance between centerlines is what measurement or less?

Clearance to cross multiple runways is typically allowed when the taxi distance between their centerlines is 1300 feet or less. This specific distance ensures that there is adequate separation and safety for aircraft taxiing across the runways, reducing the risk of potential incidents. When the distances are greater, the chances of conflicting movements increase, making it necessary to exercise more caution. The standard set at 1300 feet strikes a balance between operational efficiency and ensuring the safety of all aircraft involved in movement on the ground.
