X marks the spot not to cross at both ends of the runway
For runway maintenance works to run smoothly, being fully prepared beforehand is key. The runway needs to be closed, with two mandatory 6.2-metre-tall crosses demarcating both ends of the runway. These crosses act as a visual sign for pilots to note that the runway is not in operation as it is undergoing maintenance.
Maintaining the runway also includes the servicing of airfield lights which would require a specific tightening and untightening tool known as the torque wrench. This tool ensures that the crew apply the correct torque value to ensure that the bolts are secured, and that it will not loosen over time. This is important because loose bolts may end up becoming a Foreign Object Debris (FOD) which can disrupt airport operation.
The runway also requires repainting work to be done periodically to maintain clear and visible markings, ensuring safe and efficient navigation for aircraft during take-off, landing, and taxiing operations. As such, special paint has to be prepared beforehand to ensure there is enough for the four-kilometre-long runway. By being well-prepared beforehand and catering to the logistical demands of runway maintenance, the crew can work efficiently and avoid mishaps.
