What is FH or FOH?
"The human factor is the term used by specialists in personal safety and plant safety to describe human behavior in the workplace. It is frequently invoked in the analysis of industrial disasters and workplace accidents, and in trials and commissions of inquiry. It is associated with the idea of fault. Paradoxically, this negative conception of human intervention is based on unfailing confidence in technology and a lack of understanding of the human sciences"¹.
"These are mechanisms whose knowledge makes it possible to explain and anticipate the mental and physiological functioning of an individual or a group in a work situation".²

The FH looks for knowledge in the so-called hard sciences, such as neuroscience, physiology and ergonomics, but also in the social sciences, psychology, sociology and even ethnology.
FH or FOH therefore focuses on improving safety and/or performance. Another branch of FH,UX Design, is more specifically concerned with Ergonomics, but in the field of product design.
This branch will not be part of our offer, but we will be able to make agreements with specialists.
Why FH?
It's a question of understanding human functioning, drawing inspiration from it and taking it into account. It will no longer be up to the human to adapt to the tool, but rather to adapt the tool to the human.
In a way, this concept broadens the field and introduces the idea of "thinking about the company" as a whole (corporate culture, style of management...), of considering group behavior, of studying processes and human interactions linked to the organization.
Civil and military aeronautics, the nuclear industry (particularly in the wake of Chernobyl) and the space industry were the first to seize on this issue. Then it was the turn of certain carmakers, the medical world, rail transport and other high-risk activities to gradually join this movement, also seeking to make their activities safer.

With regard to aeronautics specifically, the continuing airworthiness regulation (EU) n°1321/2014 and the basic regulation (EU) 2018/1139 as well as the ICAO refer to the notion of "Human Factors" training through PART 145 and CAMO.
FH, Who's CAMO for?
According toAMC3 CAMO.A.305(g) , the people to be trained in FH are:
- Designated managers,
- Product line managers in the context of continuing airworthiness management,
- Compliance management system people,
- Safety management system people,
- People directly concerned by the application of FH,
- Internal occurrence analyst,
- Safety training trainer (including FH),
- Airworthiness reviewstaff,
- Technical support staff (planners, specialists, records management staff,
- Staff involved in developing and reviewing maintenance programs, assessing their effectiveness and working on reliability programs,
- Temporary staff on limited-term contracts in the above functions.
Although the CAMO Part does not formally specify it, the following personnel should also receive this type of FH training:
- The Responsible Manager: he or she must have a good understanding of his or her responsibilities towards the organization, and therefore at least an awareness of Human Factors,
-The staff of non-approved subcontractors working under cover of the organization's approval.
FH, For whom Part 145?
According toAMC 145.A.30(e), the list of people concerned by this FH training for Part 145 is as follows:
- MaintenanceManager 145, managers and supervisors,
- Quality personnel and auditors,
- Personnel dedicated to the Human Factors approach (Human Factors coordinators, Human Factors trainers....),
- APRS staff, support staff and technicians including specialized service staff,
- Technical staff working in support services such as the technical office, preparation, document management,
- Logistics staff (warehousemen, buyers...),
- Staff managing and operating ground equipment (platforms, units, access, docks...).
Although Part 145 does not specify it formally, the following personnel should also receive this type of FH training:
- The Responsible Manager: he must have a good understanding of his responsibilities towards the organization and therefore have at least an awareness of Human Factors,
- Temporary staff, on limited-term contracts,
- Staff of non-approved subcontractors working under cover of the organization's approval,
- Staff of the safety management system linked to the SGS 2008 decree (manager/coordinators, event investigators).
