Introduction
Human factors engineering (HFE) plays a crucial role in ensuring the safety, efficiency, and comfort of human interactions with systems, products, and environments. In the aviation industry, HFE is particularly important due to the potential impact of human error on flight safety. The System Index for Vertical Motion Buildup (SIVB 60) is a key tool used to assess and mitigate human factors risks in aircraft design and operation.
Understanding the SIVB 60
The SIVB 60 is a numerical rating system that evaluates the human factors aspects of an aircraft's flight control system. It is based on a series of criteria, including:
The SIVB 60 is expressed as a number between 0 and 60, with a higher score indicating better human factors performance. A score of 60 represents the ideal state of human factors engineering, while a score of 0 indicates significant human factors deficiencies.
Why SIVB 60 Matters
The SIVB 60 is an important tool for assessing human factors risks because it:
Benefits of SIVB 60 Analysis
The use of SIVB 60 analysis offers numerous benefits, including:
Stories and Lessons Learned
Story 1:
In 2013, a Boeing 777 experienced a runaway stabilizer, causing a loss of control and a near-crash. Investigation revealed that a human factors design flaw in the stabilizer trim system allowed for over-trimming, leading to the incident.
Lesson: Thorough SIVB 60 analysis can identify human factors risks and prevent such incidents.
Story 2:
The Airbus A380 is renowned for its highly automated cockpit design. However, a 2008 incident at Heathrow Airport demonstrated the importance of pilot situational awareness. The aircraft was involved in a runway overrun due to pilot misinterpretation of flight data.
Lesson: SIVB 60 evaluations should assess the effectiveness of automation and its impact on pilot awareness.
Story 3:
In 2014, the National Transportation Safety Board (NTSB) released a study on the role of human factors in commercial aviation accidents. The study found that human error was a contributing factor in over 70% of aviation accidents investigated by the NTSB.
Lesson: SIVB 60 analysis is essential for reducing the risk of human error in aviation.
