FAA Ground School Practice Test

What is one common factor that affects most preventable accidents?

1. Mechanical failure

2. Weather conditions

3. Human error

4. Pilot experience

The correct answer is: Human error

Human error is identified as a common factor that affects most preventable accidents, particularly in aviation. This is largely due to the critical role that decision-making and situational awareness play in safely operating an aircraft. Even with advanced technology and well-maintained equipment, human factors such as fatigue, miscommunication, or lack of proper training can lead to mistakes that compromise safety. In aviation statistics, a significant number of accidents can be traced back to human factors—such as errors in judgment, failure to follow procedures, or incorrect assessments of a situation. This figure highlights the importance of effective training, clear communication, and the adherence to standard operating procedures to mitigate risks associated with human error. While mechanical failure, weather conditions, and pilot experience are also important aspects of flight safety, they are often out of the pilot's control or can be managed with proper training and protocols. Thus, focusing on reducing human error through education and training has a profound impact on preventing accidents, making it the most common factor in many preventable incidents.
