What is the procedure for crossing a runway?

The procedure for crossing a runway involves ensuring clearance by the Airside Operations Centre (AOC) and following "Hold Short" protocols. This process is vital for maintaining safety on the airside, especially where aircraft are operating. Communication with the AOC is critical because it provides approval to cross the runway, ensuring that no aircraft are approaching or using the runway during the crossing.

Following "Hold Short" protocols means that vehicles must stop at the designated "Hold Short" line and not proceed onto the runway until they have received explicit clearance. This is a key safety measure to prevent accidents and maintain orderly operations on the airside.

Other options do not reflect the necessary safety protocols and could lead to dangerous situations. For instance, crossing at any time without permission disregards the need for communication and situational awareness. Relying solely on runway lights is also insufficient; it does not replace the need for clearance from the AOC. Finally, waiting for other vehicles to cross first may not ensure safety, as it does not account for the possibility of aircraft operating on or near the runway at that time.
