What is the primary cause of runway incursions?

• A. Weather Conditions
• B. Mechanical Failure
• C. Human Error
• D. Improper Communication

Answer: (C)

The primary cause of runway incursions is human error, which encompasses a range of factors related to decision-making, situational awareness, and adherence to procedures. Incursions can occur when pilots, air traffic controllers, or ground personnel misunderstand instructions, misjudge distances or speeds, or fail to follow established protocols. This type of error can result from distractions, fatigue, or incomplete information, highlighting the critical role that human factors play in aviation safety.

While weather conditions, mechanical failures, and improper communication can certainly contribute to incidents, they typically influence the environment or system rather than directly leading to the majority of runway incursions. Human error remains the leading cause, as it directly involves the actions and judgments of individuals operating within the system. This emphasizes the importance of training, situational awareness, and effective standard operating procedures to mitigate the risks associated with human behavior in aviation contexts.
