    Study Notes

    Human Factors in Aviation

    • FAA (Federal Aviation Administration): Establishes standards for human factors in cockpit design, pilot training, and CRM (Crew Resource Management).
    • EASA (European Union Aviation Safety Agency): Regulates human factors in European aviation, emphasizing ergonomics, fatigue management, and safety systems.
    • ISO 9241: International standard for ergonomics in human-computer interaction widely used in aviation.
    • OSHA (Occupational Safety and Health Administration): Enforces regulations addressing human factors in workplace safety, focusing on ergonomics and reducing human errors.

    Aircraft Design Process

    • Mission Definition: Defines the aircraft state and flight characteristics, establishing design requirements.
    • Conceptual Design: Focuses on achieving mission definition requirements through rough sketches and conceptualizing features like wing location and engine size.
    • Preliminary Design: Optimizes the conceptual design, using models for further testing and refinements.
    • Detailed Design: Finalizes the aircraft design, specifying all design elements and quantities.

    Spatial Cognition in Aviation

    • Definition: Understanding the position and movement of objects in space relative to oneself.
    • Importance: Crucial for pilots to maintain situational awareness, navigate effectively, and avoid hazards.
    • Components:
      • Mental Representation: Pilots form internal representations of the aircraft's spatial properties (e.g., bank and airspeed).
      • Geographical Awareness: Recognizing the aircraft's position relative to destinations and potential hazards (e.g., terrain, weather, traffic).

    Frames of Reference in Spatial Cognition

    • Egocentric: Reference point is the pilot's body coordinates (e.g., left-right, up-down).
    • Exocentric: External frame of reference showing airspace relative to the aircraft.

    Maps in Spatial Navigation

    • Support for Pilot Navigation: Paper or electronic maps provide essential navigational support.
    • Frame-of-Reference Considerations: Navigate between 2D and 3D maps, understand rotating maps, and manage clutter in electronic displays.

    Spatial Awareness and Flight Displays

    • Fully Egocentric Displays: Ideal for maintaining accurate flight paths by replicating control-display compatibility.
    • Exocentric Displays: Offer broader awareness of airspace, particularly for terrain, traffic, and weather monitoring.

    Decision-Making in Aerospace

    • Decision-making in aerospace: Choosing suitable actions in real-time, often under pressure.
    • Decision-making types:
      • Rule-based decisions: Following established procedures.
      • Skill-based decisions: Automatic responses based on experience and training.
      • Knowledge-based decisions: Using knowledge and reasoning to solve unique problems.

    Situational Awareness in Aerospace

    • Definition: Perceiving environmental elements, understanding their meaning, and projecting future status.
    • Importance: Crucial for flight safety, automation development, and training.

    Attention and Perception in Situational Awareness

    • Attention: Selectively focusing on particular information or tasks while ignoring others.
    • Types of Attention:
      • Selective Attention: Concentrating on specific stimuli while ignoring irrelevant information.
      • Divided Attention: Focusing on and processing multiple information sources or tasks simultaneously.
      • Sustained Attention (Vigilance): Maintaining prolonged focus on tasks over extended periods.
    • Challenges to Maintaining Attention:
      • Cognitive Overload: Processing excessive information.
      • Stress and Fatigue: Reduced attention due to stress or fatigue.
      • Automation-Induced Complacency: Reduced attention due to relying on automation.
    • Perception: Interpreting sensory input to create meaningful representations of the environment.
    • Types of Perception:
      • Visual Perception: Processing visual information from the environment and flight instruments.
      • Auditory Perception: Processing sounds like radio communications, alarms, and engine noise.
      • Spatial Perception: Perceiving position, movement, and orientation of oneself or objects.
    • Challenges to Perception:
      • Visual Illusions: Environmental factors creating misleading perceptions.
      • Spatial Disorientation: Losing a sense of the aircraft's position relative to the ground.

    Factors Affecting Cognitive Processes in Aviation

    • Environmental Factors: External conditions like noise, lighting, temperature, and workspace design influencing cognitive performance.
    • Monotony and Repetition: Repetitive tasks leading to cognitive fatigue and disengagement.
    • Duration of Vigilance Task: Vigilance typically decreases over time, with significant decline after approximately 30 minutes.

    Circadian Rhythms

    • Definition: 24-hour cycles that regulate bodily functions and processes.
    • Importance: Help living organisms respond to environmental changes.
    • Examples: Sleep-wake cycle, hormone release, and temperature regulation.
