AAM Mission Critical Commitment
Community Integration Create robust implementation strategies that provide significant public benefits and catalyze public acceptance, local regulation, infrastructure development, insurance and legal frameworks, etc.
Vehicle Development and Operations Develop concepts and technologies to define requirements and standards addressing key challenges such as safety, affordability, passenger acceptability, noise, automation, etc.
Airspace Design and Operations Develop UTM-inspired concepts and technologies to define requirements and standards addressing key challenges such as safety, access, scalability, efficiency, predictability, etc.
Achieving “systems and architecture requirements” will require enabling activities such as 1) the AAM National Campaign Series 2) a robust Ecosystem Partnership model and 3) NASA ARMD Portfolio Execution.
Critical Commitment:
Based on validated operational concepts, simulations, analyses, and results from National Campaign demonstrations, the AAM Mission will deliver aircraft, airspace, and infrastructure system and architecture requirements to enable sustainable and scalable medium density advanced air mobility operations

• Traditional SE focuses on production of many various documents:– Between documents it has become increasingly difficult to
assess completeness of information
– Difficult (if not impossible) to perform traceability
– Painful to perform impact analysis
• MBSE produces artifacts as elements in a model repository:– Traceability becomes native by relating elements to one
another.
– Because traceability increases, so does the ease of performing impact analyses.
– Because requirements, design, verification, and validation are done in the model, it provides a more complete and correct system design.
• Digital Engineering:– Traceability/Synchronization of data amongst all tools in an
enterprise
– E.g. Microsoft Project DOORS MagicDraw MATLAB

Why is NASA using MBSE?
6
Model Based Systems Engineering (MBSE) is the “utilization of dynamic models to complete standard systems engineering tasks in order to visually represent system functionality and hierarchy”
NASA’s Goal: To enable the AAM Mission Critical Commitment by capturing, organizing, tracing, analyzing and validating representative UAM system architectures and requirements
Objectives:• Develop a centralized information database accessible by the AAM Ecosystem• Improve ability to manage a very large and highly complex set of system concepts, architectures & reqmts• Build a comprehensive representative UAM System Architecture structure• Capture the necessary data and requirements that define the UAM System Architecture• Validate the UAM System Architecture using research and test data• Identify gaps in existing standards, regulations, and policies• Improve communications and interoperability across the AAM Ecosystem• Enable reusability of system elements that can be leveraged by other NASA Projects and external Stakeholders• Enable scalable solutions to the problem
