What are examples of Human Factors Jobs?
- Equipment design
- Task Design
- Environment design
- Selection
- Training
- Accident and Incident analysis
Describe the Human Error Template
- Lists errors that may be made for each task
- Works through subtasks required to complete main task
- Identify possible mistakes in subtasks (what would the consequences at each task be)
- Good predictor of real life errors
Describe the Human Factors Analysis and Classification System
-Classifies contributing factors in aviation incidents on 4 levels
- Organisational influences
- Unsafe supervision
- Preconditions for unsafe acts
- Unsafe acts
What is automation?
- Execution by a machine agent that was previously carried out by a human
- Aims to reduce human error
Describe the Information Acquisition level and how Automation can be used
Equivalent to human sensory processes
Automation:
- Seeing/hearing things in the environment/knowing where they are
- Used to simplify basic but important information acquiring tasks
Describe the Information Analysis level and how Automation can be used
Working memory and inferential processes
Automation:
-Taking information and predicting future information
Describe the Decision Selection level and how Automation can be used
Equivalanet to human decision
Automation:
-Taking information and deciding on appropriate action to do next
Describe the Action Implementation level and how Automation can be used
Replaces human voice/hand action
Automation
- Making things/systems that control planes/cars
- Can be based on decision in the prior level (Decision Selection)
When is high automation best?
For earlier tasks and low risk functions
What is reduced situational awareness a result of?
More automation causes less awareness of surroundings
What is skill degradation a result of?
By automating certain skills, their performance decreases due to not using it
How much automation should be used in Information Acquisition level?
Majority use is reliable
How much automation should be used in Information Analysis level?
A high amount is reliable
How much automation should be used in Decision Selection level?
A moderate amount for low risk functions
A low amount for high risk functions
How much automation should be used in Action Implementation level?
