Human Performance and Human Factors

Human Performance (HP) represents the human contribution to system performance and refers to how people perform their work.  Throughout the aviation system, people are both the source of some of the risks and an integral part of identifying and managing all risks.

How we support HP is informed by Human Factors (HF).  HF is concerned with the application of what we know about human beings, their abilities, characteristics and limitations, to the design of equipment they use, environments in which they function and jobs the perform. 

HP considerations are key to enabling safe operations, whether focused on flight and cabin crew, air traffic operators, maintenance engineers, or other aviation professionals.  HP-related areas of work are dispersed across a range of topics covered both within and outside of the OPS Section including:

  • Analysis of safety occurrences
  • Change management and introduction of new systems
  • Fatigue management
  • Human-centred design (whether hardware, software, processes or procedures)
  • Remotely Piloted Aircraft Systems
  • Safety risk management
  • Training

The Manual on HP for Regulators (Doc 10151)* brings to focus the human contribution to the global aviation system and supports regulators to make it easy for people in the aviation system to "do the right thing" and avoid negative safety consequences.  It addresses HP considerations in regulatory activities such as the development of appropriate regulatory material, through evaluating, accepting and approving organizations, systems, processes and people, and through continued surveillance.   It also illustrates how HP considerations are embedded in key oversight responsibilities and activities that are included in an SSP.
