104 Understanding human factors in working with drones

Updated: Dec 1, 2024

Improving drone operations with awareness of human factors such as behavior, decision-making, and risk management for safety and efficiency. — Improve drone safety by understanding human factors, decision-making, and risk management for improved operational efficiency and success.

Human Factors in Drone Operations: Enhancing Awareness and Safety

Despite advances in drone technology, human factors remain a critical component in ensuring operational safety. Research shows that 80% of aviation accidents involve human error. This article explores how understanding human behavior, decision-making, and risk management can improve safety and efficiency in drone operations.

Introduction to Human Factors

Human factors in drone operations focus on:

Aeronautical Decision-Making (ADM): A systematic approach to risk assessment and stress management.
Attitude Awareness: Understanding how personal attitudes influence decision-making.
Stress Management: Recognizing optimal stress levels for peak performance.

Key Insight: Proper preparation and risk awareness can reduce human error and enhance flight safety.

The effects of stress on work performance, focusing on optimal levels of stress that promote greater concentration and excessive stress that leads to confusion or unconsciousness. — Moderate stress can improve concentration, while excessive stress can cause confusion or panic.

Understanding and Managing Stress

Stress affects performance in various ways:

Optimal Stress: Improves focus and reaction time.
Excessive Stress: Can lead to confusion, panic, or loss of control.

The Yerkes-Dodson Law demonstrates that performance peaks under moderate stress but declines with under- or overstimulation.

Coping Strategies:

Conduct thorough pre-flight checks.
Avoid restricted and dangerous areas.
Assess location and safety conditions.
Monitor weather and prepare the team.
Develop emergency response systems.

Flying drones in quiet areas, with advice on how to avoid stress, including slow speeds, defensive flight patterns, and getting enough rest before operating. — Tips for avoiding stress while flying: Fly slowly, choose a quiet area, use defensive flying techniques, and always fly well-rested.

Avoiding Stressful Situations

Fly at slower speeds.
Choose calm, less crowded operational areas.
Maintain a defensive flying style.
Ensure adequate rest before flights.

Avoiding Alcohol and Drugs During Flights

Substances such as alcohol impair critical functions:

Vision: Night blindness and tunnel vision.
Coordination: Reduced motor accuracy.
Reaction Time: Slower responses to changes.

Prohibition: Avoid flying under the influence of alcohol or non-prescribed drugs, as the effects can linger into the next day.

Drone operators must manage rest and fatigue to ensure safe operations, with an emphasis on concentration, decision-making, and coordination. — Managing rest and fatigue is essential for safe drone operations. Get enough rest, avoid night flying when you feel tired, and take regular breaks to maintain focus and coordination.

Fatigue Management

Impact of Fatigue:

Impaired concentration.
Hindered decision-making.
Reduced coordination and sensory perception.

Prevention Tips:

Get adequate rest and take breaks during long operations.
Avoid night flights when feeling fatigued.
Pay attention to fatigue signals and pause when necessary.

Visual and Sensory Perception

Scanning the Environment:

Practice systematic scanning of the drone, control unit, and surroundings.
Use peripheral vision to detect motion and obstacles.

Adapting to Light Conditions:

Adjust screen brightness for daytime and nighttime operations.

Listening and Other Senses:

Avoid headphones to hear environmental or drone-related audio cues.
Use the sense of smell to detect burning components.

Understanding Peer Pressure

Negative Peer Pressure:

Avoid risky behaviors to impress others, such as flying in unsafe conditions.

Positive Peer Influence:

Surround yourself with individuals who prioritize safety and professionalism.

Tip: Trust your skills and adhere to safe practices regardless of external influences.

The Role of Automation in Drone Operations

Automation enhances efficiency but requires close oversight:

Benefits:

Reduces physical and mental workload.
Improves navigation accuracy with features like Return-to-Home (RTH) and pilot-following modes.

Challenges:

Overreliance on automation may diminish pilots' situational awareness and manual skills.
Faulty automation can cause unexpected issues.

Best Practices: Use manual controls whenever possible to maintain proficiency and rely on automation only when necessary to enhance safety.

Risk Awareness and Decision-Making

Influential Factors:

Overconfidence and Experience:
- Familiarity with successful missions can lead to complacency.
- Avoid exceeding personal or procedural limits.
External Conditions:
- Monitor wind changes, battery levels, and flight paths.

Guidelines:

Prioritize flight safety over mission completion.
Set personal and operational limits.
Anticipate risks for every flight.

Hazardous Attitudes and Remedies

Attitudes significantly influence decision-making. Recognize and address these five hazardous attitudes:

Attitude	Example	Solution
Anti-Authority	"Don’t tell me!"	"Follow the rules—they’re right."
Impulsivity	"Do it quickly!"	"Think before acting."
Invulnerability	"It won’t happen to me!"	"It could happen to me."
Macho	"I can do it!"	"Taking risks is foolish."
Resignation	"What’s the use?"	"I can make a difference."

Tip: Recognizing and countering hazardous attitudes can improve judgment and reduce errors.

Conclusion

Human factors are crucial to safe and efficient drone operation. Pilots can improve their situational awareness, decision-making, and overall safety by understanding stress, fatigue, visibility, peer pressure, and automation.
