Runway Protection Area (RPA) Intrusion Detector

 (RPA Intrusion Detector deployed at runway holding point)

Many large airports have Runway Protection Area Detectors using inductive loop technology that are already implemented. There is a significant cost involved in maintaining and replacing traditional inductive loops.

The impact on operations is also high during maintenance since taxiways have to be closed down for a longer period of time than with a surface mounted solution. Also our technology is capable to detect humans and larger animals.

ASW RWY Protection Area Intrusion Detectors can be setup in two different configurations.

The first option is to place the barriers to cover the paved areas. This is normally placed around the stop bars where aircraft or vehicles are normally taxiing.

The second options is a total RPA protection that covers the whole ground boundary of the runway protection area. In this configuration the sensors covers not only the paved areas but are placed to form a square around the runway.

For airports with a lot of wildlife or with higher security classification this option may be considered. Regardless of the option chosen the main purpose of this application is to provide Runway Protection Area Intrusion detection.

This configuration allows the monitoring of passing aircraft, or vehicles, with direction and speed information and exact time stamp information, and delivered with instantaneous response time to the Controller.

Upon violation of the barrier it provides audible and visual alarm for controllers at either a stand-alone HMI provided by ASW or SMGCS/A-SMGCS surveillance data display, the interface to which employs ASTERIX protocols.

The ASTERIX data transmission is sent to the Surveillance Data Fusion System from any 3rd party provider providing highly accurate data that can support tracking and reduce nuisance alerts caused by low accuracy target data from other surveillance sources.

When all stop bars at RWY entry points are equipped with ASW Barrier, a complete RWY Protection Area can be realized. This requirement is part of future European legislation and already drafted in NPA 2011-20 B.II.
