Airport Runway Protection Zone and Inner Safety Zone

Runway Protection Zone (RPZ): A trapezoidal area at ground level (formerly called a clear zone) extending from the end of a runway and centered on the extended centerline of the runway. Its purpose is to provide a safe, clear space for aircraft takeoffs and approaches, and to protect people and property on the ground. Inner Safety Zone (ISZ - also referred to as “Inner Approach / Departure Zone"): The areas located at the ends of runways, immediately after and sometimes alongside the RPZs.
