For which end of the runway will a pilot or military authority request the cable or barrier to be raised?

A pilot or military authority will request the cable or barrier to be raised at the approach end of the runway. This is primarily due to safety and operational protocols. The approach end refers to the area where aircraft begin their final descent towards landing. It is crucial to ensure that any barriers are raised or removed to facilitate a smooth approach for landing aircraft, particularly when visibility is compromised or when flights are being managed tightly due to operational demands.

Raising the barrier at this point ensures that aircraft can safely land without obstruction. This management of the barrier system is essential to prevent accidents or incidents during the critical phases of landing. The other choices focus on areas that either occur before or after the aircraft has touched down, where the need to raise barriers is less immediate or not relevant to the landing process.
