Why is the E-5 barrier primarily used in the overrun?

The E-5 barrier is primarily utilized in the overrun area because it is specifically designed to minimize the risks associated with aircraft overruns and has a significant advantage concerning the required maintenance and operational readiness after an event. The correct response emphasizes the extensive amount of time it takes to reset the barrier. This is crucial because, after an aircraft impact, restoring the barrier to a safe and functional state can be a time-consuming process, which impacts the overall responsiveness and availability of airport operations.

In scenarios where quick recovery and minimal downtime are important, the ability to efficiently reset the barrier becomes a critical operational consideration. This design characteristic ensures that it effectively serves its purpose without causing prolonged delays in air traffic and enhances overall safety.
