The introduction of the term to the English lexicon is widely attributed to British psychologist Hywel Murrellat the meeting at the UK's Admiraltywhich led to the foundation of The Ergonomics Society.
As with the chief pilot, the mechanic acts as an advocate for operator or repair station counterparts. The appointment of a chief mechanic grew out of the recognition that the maintenance community contributes significantly to the success of airline operations in both safety and on-time performance.
Drawing on the experience of airline and production mechanics, reliability and maintainability engineers, and human factors specialists, the chief mechanic oversees the implementation of all maintenance-related features.
Computer-based maintainability design tools. Beginning with the program, Boeing stopped building full-scale airplane mockups, which in the past helped determine whether a mechanic could reach an airplane part for removal and reinstallation.
Now, using a computer-aided three-dimensional interactive application CATIABoeing makes this type of determination using a human model.
In addition to ensuring access and visibility, human factors specialists conduct ergonomic analyses to assess the human capability to perform maintenance procedures under different circumstances. For example, when a mechanic needs to turn a valve from an awkward position, it is important that the force required to turn the valve must be within the mechanic's capability in that posture.
For another example, when a maintenance operation must be accomplished in poor weather at night, secure footing and appropriate handling forces are necessary to protect the mechanic from a fall or from dropping a piece of equipment.
Fault information team FIT. Human factors considerations in maintenance also led to the formation of the FIT. The FIT charter has since expanded to promote consistency in maintenance processes and design across all systems and models. The goal is to enable mechanics to maintain all Boeing commercial airplanes as efficiently and accurately as possible.
This cross-functional team has representatives from maintenance, engineering, human factors, and operators.
For the text of these displays, Boeing has created templates that provide for common fault menus for all systems. The interface should look the same to the mechanic regardless of the vendor or engineering organization that designs the component. The FIT reviews all information used by the mechanic, including placards, manuals, training, and size, location, and layout of controls and indicators, and works with the engineers to develop effective, consistent displays.
The team also provides input and updates to Boeing design standards and requirements. In the early s, Boeing formed a maintenance human factors group. The group also helps maintenance engineers improve their maintenance products, including Aircraft Maintenance Manuals, fault isolation manuals, and service bulletins.
As maintenance support becomes more electronically based, human factors considerations have become an integral part of the Boeing design process for tools such as the Portable Maintenance Aid.
In addition, the group is developing a human factors awareness training program for Boeing maintenance engineers to help them benefit from human factors principles and applications in their customer support work.Human factors involves gathering information about human abilities, limitations, and other characteristics and applying it to tools, machines, systems, tasks, jobs, and environments to produce safe, comfortable, and effective human use.
FDA Guidance on “Applying Human Factors and Usability Engineering to Medical Devices” and the “List of the Highest Priority Devices for Human Factors Review” have recently been released to help improve device design and instructions for use to minimize user errors and potential harm.
There are several factors to consider when assessing the necessity of a human factors study for premarket submission and while designing the study. In this webinar, attendees will learn more about successfully applying and executing human factors and .
