Abstract:The FAA Air Traffic Safety Oversight Service (AOV) initiated a research project, the Integrated Domain Assessment (IDA), to support its approval, acceptance, and concurrence process for Safety Risk Management Document (SRMD) review. The initial IDA prototype developed as part of this research focused on SRMDs for new and modified National Airspace Systems (NASs) and is based on a model of the NAS architecture integrated with system safety hazard data. As part of future development, the IDA will be expanded to provide decision support to AOV in evaluating SRMDs for air traffic control (ATC) procedure changes related to separation minima. The technical implications of integrating ATC procedure SRMDs in the IDA must be examined to ensure that the IDA model and prototype design are adaptable for eventual inclusion of ATC procedure SRMDs. The purpose of this study is to understand the characteristics of ATC procedure changes and associated SRMDs, recommend IDA model updates, and identify further research needed to incorporate ATC procedure changes and related SRMDs. The feasibility of modeling interrelationships between ATC procedure changes and NAS systems is also explored. This study provides an overview of FAA Order 7110.65 and characterizes a sample of associated SRMDs for ATC procedure changes. Technical considerations for IDA model updates are explored, such as the types of hazards identified in procedure SRMDs; differences between procedure and system SRMDs; and potential interrelationships between procedure changes and systems. The recommendations from this study will be used to guide future research to extend the IDA concept of operations and data models to integrate ATC procedures and provide decision support for AOV’s evaluation of both system- and procedure-related SRMDs.
