Study on the position of Visual screen in airport constructed End-Around Taxiway

Abstract

In order to reduce the number of aircraft crossing the runway and improve the safety of the airport operation, some multi-runway airports plan to construct EAT (End-Around Taxiway: A taxiway crossing the extended centerline of a runway, which does not require specific clearance from air traffic control to cross the extended centerline of the runway). Through a partial or complete masking effect, the visual screen will enable pilots to better discern when an aircraft is crossing the active runway versus operating on the EAT. The placement and configuration of EATs must take into account additional restrictions to prevent interfering with ILS system, approaches and departures from the runway(s) with which they are associated. In this paper, the influence of EAT screens on the Instrument Landing System(ILS) in the airport is studied, which provides theoretical guidance for airport construction.
