RECOMMENDED PROCESS FOR ADDRESSING HUMAN FACTORS/PILOT
OBJECTIVE OF THE PROCESS
This section provides a recommended process for demonstrating compliance to human
factors related regulations as well as identifying, evaluating and resolving human
factors/pilot interface issues regarding the certification of avionics. The process is intended
to be guidance and not a means of compliance (MOC). While the focus of the process is
certification, it is understood that identifying and resolving the human factors issues of the
pilot interface is conducted as part of both the design and certification process. In fact,
addressing the human factors aspects of the pilot interface is an activity that is best
conducted early and continuously throughout the engineering design development program
and not something that happens only at the end of a program during the formal certification
test phase. As such, there may be some information generated as part of the design process
that could be used for certification as well. This information may include the results of
engineering analyses, evaluations (mock-ups, bench, laboratory, simulator or aircraft) as
well as other methods used to identify and resolve human factors issues.
The process described in Section 2.3 below addresses the importance of involving the
certification authority early in the overall development process for the identification and
resolution of human factors certification issues related to avionics. This recommended
process is intended to be useful for both the applicant and the certification authority as it
describes the expectations of each in addressing human factors/pilot interface issues during
the certification approval process. Specifically, the recommended process defines methods
and deliverables expected by the appropriate party. The ultimate goal of this section of the
document is to present a well-understood, timely and consistent process to promote safe
systems as well as to minimize late and costly required design changes.
DESCRIPTION OF HOW THE PROCESS IS TO BE USED
The process steps identified in this section are intended to be used as a guide for both the
applicant and the certification authority.
The process includes five steps, which explicitly focus on activities that have unique human
1. Concept Review
2. Agreement on Plan for Human Factors Compliance
3. Applicant Continues to Develop the Product
4. Formal Testing (conformed articles)
5. Certification Deliverable Submittal and Certification Authority Review
Each of the five process steps includes all or many of the following items:
Description of the Activity for the process step.
Inputs that are recommended to carry out the tasks and activities of the process
Tasks and Activities carried out in the process.
Outputs are recommended deliverables resulting from the process step. These may
include formal and/or informal reports, white papers and/or position papers,
requirement documents, and documentation of decisions and agreements made.
