airport. As such, there is no cookie cutter approach to PIDS design that can be recommended. Certainly,
similarities will exist across operational environments and lessons learned from previous PIDS
implementations should be pursued. A layering approach where multiple sensing technologies are applied
in tandem could mitigate these issues. The layering of multiple sensing technologies is described in Section
The operational architecture directly drives the procedures whereby detections are addressed. These
procedures are reflected in a process workflow. This workflow identifies the key decision points that occur
as an observation or event flows through the high-level stages of detection, assessment and response. The
PIDS system should directly and for more complex systems, automatically implement this decision-making
workflow such that detections can be easily analyzed by the operator to allow rapid location, identification
and response to an alarm condition Further, this decision-making workflow may allow the system to
automatically identify what and where the threat is, with or without operator control, in a structured,
predictable and repeatable fashion.
Every airport has distinct and potentially unique environmental challenges that may make a uniform design
approach undesirable or unfeasible. The selection, positioning and layering of sensing technologies as well
as identification of associated system-level KPPs must account for these environmental challenges. Each
of the examples below potentially poses a different security, sensor, response, or timeline challenge.
Weather including wind, rain, snow and more extreme phenomena to include locations that
experience high incidences of lightning strikes.
Perimeter characteristics including trees, rivers, water and impact on security
Environmental Restrictions including wetlands, animal habitats, etc.
Proximity features of public side and standoff distance of people, roads, vehicles Examples include
environments where there are heavily traveled roads alongside the perimeter, sidewalks along the
secure line, boats operating within close proximity, public access adjacent to taxiing aircraft, etc.
Operating Characteristics such as the distinction between commercial and GA/corporate
The system design should reflect the constraints posed by the integration of the legacy equipment,
performance of new technology to address the operational requirements, and availability of various sensing
technologies. The selection, positioning and layering of sensing technologies as well as identification of
associated system-level KPPs must account for these considerations. A flexible approach to this design
consideration is recommended given the fluidity of current technology and future technology trends.
Any PIDS system design should adhere to the infrastructure requirements and constraints of the overall
airport operating environment. Considerations may comprise a wide variety of environmental conditions,
physical constraints or legacy system and operational performance requirements. Examples include
