Part 161 imposes what kind of analysis before seeking FAA approval for new noise rules?

• A. Cost-benefit analysis
• B. Environmental impact analysis
• C. Safety risk assessment
• D. Financial feasibility

Answer: (A)

Part 161 requires a cost-benefit analysis to be conducted before pursuing FAA approval for new noise rules. This means weighing the costs imposed on airports, airlines, and other aviation stakeholders against the expected benefits to the public, such as reduced noise exposure and associated health or quality-of-life improvements. The goal is to determine whether the proposed rule yields a net positive impact for society and is justified to move forward.

Environmental impact analysis and safety risk assessment can be part of broader regulatory reviews, but the specific mandate here is the economic evaluation that quantifies costs and benefits. Financial feasibility is related but is encompassed within the broader cost-benefit framework rather than the primary requirement.
