Where is the E-5 unidirectional barrier typically installed on the runway?

The E-5 unidirectional barrier is typically installed on the overrun of the runway to enhance safety measures. The purpose of this barrier is to prevent aircraft from inadvertently leaving the runway and entering areas where they could be at risk, such as adjacent roadways or other operational zones.

Installing the barrier on the overrun area is strategic, as this section is designated for emergency use and serves as an extra margin of safety for aircraft that may be unable to stop within the normal runway length. This placement effectively mitigates the risk of potential incidents by providing a physical barrier that directs wayward aircraft back toward the runway rather than allowing them to veer off into more hazardous environments.

The overrun area is specifically designed for these kinds of safety features, distinguishing it from the runway's start or end, where aircraft operations are at their most critical. Hence, this positioning of the E-5 barrier aligns with industry practices focused on ensuring the highest level of safety during takeoff, landing, and potential emergency situations.
