When a pilot receives the message 'CLEARED TO CROSS AT', what is the pilot instructed to do?

When a pilot receives the message 'CLEARED TO CROSS AT', it indicates that the pilot is authorized to cross a specific point in the airspace, typically an intersection or a runway, at the specified location. This instruction is generally associated with the management of aircraft movements on the ground or in the airspace, ensuring safety and efficiency in operations. The term 'cross' signifies that the pilot is allowed to navigate their aircraft over or through the designated point, which is crucial for maintaining proper separation from other aircraft and adhering to the air traffic control instructions.

Understanding this term is vital for pilots as it relates to their awareness of spatial positioning and compliance with air traffic instructions, ultimately ensuring safe flight operations. In contrast, communicating with the control tower, descending to a designated altitude, or proceeding directly to the outer marker do not directly relate to the action implied by being ‘cleared to cross’.
