The Four P’s: Policy
– HF is part of our SMS policies– Clearly defined objective– Clearly defined responsibilities
Human Factors Policy:An example
The Vice President, Safety & Quality is responsible for:
(a) reviewing and assessing the effectiveness of safety-related policies and procedures in taking account of the role of human and organizational factors;
(b) providing or facilitating the provision of Human Factors training as it relates to corporate safety management;
(c) evaluating the application of Human Factors in hazard analyses and occurrence investigations; and
Hazard Analysis Procedure
- Use the PETE model to describe the system- Task
- Sequence aircraft for landing
- Person – ATC- Qualified and checked-out- Experience and qualifications
- Equipment- Radio- Radar Display
Hazard Analysis Procedure
- Introduce change (new sequencing tool) and identify potential impact on operator performance- Task
- Sequence aircraft for landing (?)
- Person – ATC- Qualified and checked-out- Experience and qualifications (?)
- Equipment- Radio- Radar Display (?)
The Four P’s: Processes

Safety Culture Assessment Tool
– Emphasis and importance given to Safety– Degree of cooperation and cohesiveness– Match between task and resources – Effective and free flowing communications – Clear mapping of the safety state – Strong learning orientation – Clear lines of authority and accountability

– Operations Safety Investigation (OSI)– NAV CANADA Aviation Safety Tracking
System (NCASTS)– Safety Culture Assessment Tool– Corporate Safety Planning
Thoughts on Approach
• Start with focused activity• Take small steps • No one element should be thought of as the
panacea to improving safety• Still need to cover the basics• It’s integrated – it’s the way we do business • Not a huge dedicated resource requirement
