Flight Crew Error and Inadvertant Operation
The new regulation 14 CFR 25.1302 is the first regulation to include explicit requirements for design attributes related to avoiding and managing flight crew error. This new rule represents a much more global approach to human factors on the flight deck and will require the system/equipment designer to consider human error and feedback in their design and test of flight deck interfaces. It is harmonized with the EASA rule, EASA CS 25.1302, which was released in 2006. Since the release of the EASA rule several manufacturers have gained valuable experience in applying the new rule and specifically how to identify and address the design attributes that relate to avoiding and managing flight crew error. Due to the shift to a more human-centered approach, research is needed to assess the effectiveness of current human-centered design and evaluation methods, and to identify lessons learned and recommended practices. It is also necessary to identify additional resources or policy guidance that may help applicants and regulatory personnel in the application of this new regulation.
The purpose of this research project is to collect lessons learned and best practices in order to support advisory guidance used for demonstrating compliance to the planned 14 CFR 25.1302. This is a new regulation that includes the requirement to "enable the flight crew to manage errors resulting from the kinds of flight crew interactions with the equipment that can be reasonably expected in service". Additionally this research will focus on 14 CFR 25.777 and will support 14 CFR 23/27/29.777 requirements to "prevent confusion and inadvertent operation" of flight deck controls. The intent of the work is not to replace the guidance provided in Advisory Circular AC 25.1302 or the new AC 20-CNTRL, but to provide supplementary information to support the methods used to comply with the unique nature of the new regulation.
The research will provide scientific and technical information to assist applicants and regulatory personnel in identifying recommended practices for using the various methods of showing compliance with 14 CFR 25.1302, specifically the requirement to enable flight crews to manage errors reasonably expected in service.
