Action
Final rule.
Summary
The FAA is amending the airworthiness standards for transport category airplanes concerning flightcrew alerting. These standards update definitions, prioritization, color requirements, and performance for flightcrew alerting to reflect changes in technology and functionality. This amendment adds additional alerting functions, and consolidates and standardizes definitions and regulations for flightcrew warning, caution, and advisory alerting systems. This action will result in harmonized standards between the FAA and the European Aviation Safety Agency.
