Human Factors Toolbox

FAA offers the Maintenance Human Factors Presentation System

The media takes three formats. First, the foundation is based on PowerPoint slides. The slides have a standardized format, modern graphics, and optional notes for the speaker. Newly produced video snippets, two to four minutes in length, are the anchors for primary sections of the system. There are 10 videos. The third media offering is Adobe Flash animations, provided by Lufthansa Technical Training. Lufthansa saw the value of the MHFPS for not only FAA inspectors, but also for the world. Therefore, it contributed production ideas and approximately 40 animations from the nearly 250 contained in its human factors web-based training program ( The MHFPS is not a substitution for the computer-based training of Lufthansa or any other CBT provider. Repeat — the MHFPS is not CBT and is not a substitute for the many excellent courses and human factors consulting offered by many first-rate providers worldwide.

The MHFPS uses easy-to-remember methods to apply human factors principles at work and in life outside of work. One example is the four-minute video on “human factors spectacles” (Figure 2). This segment provides a way to see human factors not only in the workplace, but also in one’s personal life. It permits the presenter to run the video and let it serve as a basis to discuss various ways to view human factors issues. Users have commented that the dialogue between the actors in the videos is fun to watch, while delivering a very useful message.

The largest and most content-intense section in the MHFPS addresses the PEAR model, developed by Bill Johnson and Mike Maddox in the early 1990s. PEAR represents people, the environment in which they work, the actions that they perform, and the resources necessary to perform work. Figure 3 is a sample of a graphic from one of the Lufthansa animations that answer the question, “Why use models to explain things?”

The PEAR model is a way for the presenter to explore a variety of human factors that affect work and life. The system lets a presenter provide as much, or as little, detail that they choose. For example, the MHFPS has a video, many animations, and a number of slides that address fatigue issues. Fatigue issues are included in the “people” portion of the PEAR model chapter.

One size doesn’t fit all
It is a challenge to present slides made by another. The MHFPS system offers notes for each slide, but presenters are not bound to a script or limited to the nearly 150 slides in the program. The introductory video encourages you to add your name and logo. You should take ownership of the presentation. One of the videos describes MHFPS as a “giant Lego-like collection of human factors information.” Use the blocks to build a presentation that works for you.

Availability and distribution
The MHFPS is available through professional associations, local FAA offices, other international regulators, and at FAA booths at conventions. The Table on Page 30 shows the best contact to obtain a DVD from your region. FAA is welcoming others to help distribute the system worldwide.

Other documents on the MHFPS DVD
In 2006 and 2007, FAA teamed with industry to develop two operators’ manuals for human factors (Figure 4). One manual is for aviation maintenance and the other is for other airport operations — like ramp, fueling, deicing, baggage, and more. The maintenance version won the FAA Administrator’s 2006 award for Use of Plain Language. These two manuals are complementary to the MHFPS and are packaged on the DVD. They are also available at

The author acknowledges that the MHFPS was a combined effort of the Flight Standards Aircraft Maintenance Division including Jay Hiles, Jennifer Ciaccio, and Marcus Cunningham, with additional support of the FAA Chief Scientific and Technical Advisor Program. The animation files, provided by Lufthansa Technical Training, were invaluable to the program development and quality.
