Intended-Users-5-characteristics (2)

Before you delve into the design of a new system, you are likely aware that you need to define your intentions for the system. This includes not only the intended function and the intended context, but also a clear description of your intended users. Intended users—the type of people who you will use your system—will greatly impact design decisions that you make early in the process. If you’ve ever gone to parent-teacher night and been forced to sit in your kindergartner’s chair, you’ve already got a good idea of what we mean when we talk about how defining intended users will impact design decisions. Why define your intended users? Defining your intended users means that you will be more likely to make design decisions that allow your users to operate the system to achieve its intended function effectively, efficiently, and comfortably. (Think about that kindergarten classroom chair.) When you fully … Continue reading

A lot of airplane and avionics manufacturing companies are starting to prepare their teams to address the newly released FAA regulation covering human factors issues: 14 CFR 25.1302.  There is a lot to learn, but here are the top five things you should know. In a nutshell, 14 CFR 25.1302… 1. Applies to everything in the flight deck meant to be used by the flight crew It is a general applicability regulation that applies to all systems and equipment that will be used by the flight crew in any way during their flight duties. 2. Applies to system individually as well as possible impact on other systems Showing compliance to the regulation must include human factors considerations on the design and performance of the system or equipment in isolation, as well as how it will be used with other flight deck systems or equipment.  The potential impact on the use … Continue reading

3rd post in the series Whether you are designing and then later modifying a single avionics component or a full aircraft, aviation projects can take a long time to move from paper to production. Since a certification basis is typically defined early in a product’s life, there can be a fairly long lag between the time a new rule is released and when that rule officially gets added to the laundry list of rules that a particular product must comply with. So, the big question is: when will the newly released 14 CFR 25.1302 get added to your cert basis? We heard this question a lot during the recent research project that we did for the FAA to gather information about the state of industry and FAA understanding and practices that may impact the effective implementation and compliance with the (at the time proposed) 14 CFR 25.1302 regulation. (Note: This … Continue reading

Screenshot of Overview of HFYI Training Series

We are excited to release a video overview of the aviation design and certification processes that make up the foundation of our new aviation training series. Click Here for immediate access to the overview video on The free presentation provides a global look at how we break down the design process that we use for our 9 course training series. We are a human factors training and research company, so we focus on the aspects of the process that relate to the human factors design and certification decisions that must be made, although we recognize that there are many other important aspects to the overall process. The team at Research Integrations developed this process breakdown based on our work over many years addressing the human factors aspects of aviation design and certification for the FAA, NASA, as well as others. In particular, our work as part of the team … Continue reading

This is an exciting day! After a lot of hard work by many folks, 14 CFR 25.1302 regulation has been released. As you may already know (or have read about in our blog series about the 14 CFR 25.1302 regulation), 14 CFR 25.1302 is a general applicability FAA regulation that includes explicit requirements for design attributes related to avoiding and managing flight crew error. While FAA 14 CFR 25.1523 and corresponding Appendix D have addressed some related design attributes, this proposed FAA regulation represents a much more global approach to human factors on the flight deck and will require system and equipment designers to consider human error and feedback in their design and testing of flight deck interfaces. And, today, the final rule for 14 CFR 25.1302 has been published in the Federal Register.  You can find the published rule on the Federal Register: 14 CFR 25.1302 Installed Systems and … Continue reading

Everyday small aircraft and business jets fly safely and effectively with a single pilot behind the control stick in the flight deck.  But, currently large aircraft (e.g., those with a maximum takeoff weight (MTOW) greater than 12,500 lbs), must have at least two pilots in the flight deck to fly the plane.  So, what would it take to be able to certify large Transport Category Aircraft for Single Pilot Operations (SPO)? Well, we’ve just begun a research project for NASA to begin to contribute to answering this question.  In our project, we will explore the processes used to evaluate and certify an airplane design and operations for a particular minimum flight crew (single pilot or crew of two or more).  We will use this information to build an understanding of certification issues and regulatory challenges that would be related to gaining FAA approval for Single Pilot Operations in categories of … Continue reading

Pilot manually flying aircraft.

Recently we have been involved in providing evaluations and coaching addressing the safety impact of policies and procedures related to pilot use of automated systems in a large international airline.  One of the first questions typically raised in this type of project is: How can we reduce the possibility of pilots losing their manual flying skills when they routinely use automated systems to fly the airplane? In other words, we are often asked for strategies an airline can use to address the complex web of trade-offs associated with the consistent, economical, and safe routine operation of transporting passengers and the potential for unexpected situations in which pilot expertise, judgment, and skills are necessary for a safe outcome. This is a balancing act that must be performed by each airline within their own unique blend of national, corporate, and safety cultures.  Unfortunately, one solution does not work for all companies. But, … Continue reading

Unmanned Aerial Vehicle (UAV)

We are very excited to share that we have added a report to our website that summarizes our first year efforts on tasks related to developing human factors guidelines for Ground Control Station (GCS) design and operations. This work is being performed as part of the Human Systems Integration (HSI) component of the NASA Unmanned Aircraft System (UAS) integration in the National Airspace System (NAS). In 2012, we focused our efforts on gathering and describing information to be used as a foundation for developing the human factors guidelines and for future tasks in support of the NASA UAS Integration in the NAS project. Year 1 Tasks and Objectives In Year 1 of this project we completed a review of the 14 CFR Part 23 and Part 25 FAA regulations, analyzed the results and determined requirements for ground control stations that may not be adequately covered by the regulations. In addition, … Continue reading

2nd post in the series As you may have read in the first post of this series, a new FAA regulation is tentatively slated to hit the streets in early 2013.  It is the proposed FAA 14 CFR 25.1302 Installed systems and equipment for use by the flightcrew and is the first general applicability FAA regulation to include explicit requirements for design attributes related to avoiding and managing flight crew error. You may be asking: Why has this regulation been created?  Haven’t we already covered everything important in the regulations of 14 CFR Part 25? Well, let me give you my answer (which obviously is not an official FAA response … cue announcers voice: “the views and opinions expressed in this post are those of the author and do not necessarily reflect the FAA, its employees, or the Screen Actors Guild. No animals were harmed during the writing of this … Continue reading
