When taxiing, what must you receive to cross a runway?

To safely cross a runway while taxiing, you must receive a specific runway crossing clearance from air traffic control. This procedure is essential for maintaining safety on the airport surface, as runways are active and can be used by departing or arriving aircraft at any time. The clearance ensures that you have confirmed permission to cross the designated runway, reducing the risk of a runway incursion, which could lead to dangerous situations for both the taxiing aircraft and those in the air.

Receiving a specific clearance highlights the importance of communication with air traffic control. It is critical that pilots understand that not all taxiing actions require the same level of clearance. A general or taxiway clearance does not provide the same assurance of safety when it comes to entering or crossing a runway. Properly adhering to this requirement is a fundamental aspect of safe operations at an airport, emphasizing the critical nature of situational awareness and following air traffic control instructions meticulously.
