Runway Incursion Avoidance Series 2 – Human Factors (part 1) 👫👫

The airport movement area contains systems designed to prevent and lower the risk of runway incursions and aircraft ground collisions. Despite the sophistication and effectiveness of runway protection systems, runway safety data suggest a steady increase in surface events since the end of the Covid-19 Pandemic. This can be partially contributed to increased operations, however if the recent trends continue, incursions and surface incidents will soon surpass pre pandemic numbers. Runway incursion and airport surface incident statistics can be found here: Runway Safety Statistics (faa.gov) The human interaction with simple and complex systems, machines, processes, and environments has been identified as a direct cause and contributing factor to countless runway related accidents and incidents. In Series 2 we will explore the human aspect of runway incursion avoidance, and how this effects airport movement area safety.

What we heard about Human Factors 👂

Explaining the human aspect of safety in the Airport Operations Area AOA is no small task. Pilots, controllers, mechanics, ramp workers, fire fighters, police, security, field maintenance, airside operations, and construction workers, all perform their daily task on the movement and non-movement areas of the AOA. With an increase in airline service levels, an increased presence of aeronautical service providers exists on the AOA as well. Each employee no matter the classification and skill level, have specific tasks, procedures, and training exclusive to their organizational goals. Each classification also strives to attain the highest level of quality regarding safety and productivity. Despite these efforts and systems designed to manage safety efficiently, accidents, incidents, and near misses still occur on active runway surfaces.


The Federal Aviation Administration FAA defines Human Factors Safety as:

“A multidisciplinary effort to generate and compile information about human capabilities and limitations and apply that information to equipment, systems, facilities, procedures, jobs, environments, training, staffing, and personnel management for safe, comfortable, and effective human performance” (FAA Order 9550.8A).

Simply put, abating human factors errors encompasses the application of research from sciences, and engineering, to understand the characteristics and limitations of human workers as they interact with work systems.  The mental and physical capabilities of the human workers must be matched to all aspects of the job, or performance and safety will be negatively affected.

Scientific disciplines involved in human factors research that affect runway safety include physiology, phycology, kinesiology, and neuroscience. Scientist such as phycologist strive to apply their broad disciplines to better understand human behaviors and mental capacities. For example, a clinical phycologist will strive to identify the effects of medications, recreational drugs, and alcohol on how we think and make decisions. Human factors experts apply the research and findings from scientist to reduce safety risk. Engineers involved in runway incursion avoidance include safety, industrial, systems, and mechanical. Engineers develop tools and machines that increase human output and safety for a given job task or system interface. In contrast human factors experts examine the application of the tools and or machines developed by engineers from the human perspective to increase safety and efficiency.  Often the discipline of workplace Ergonomics can be mistaken and used as a catch all for the abatement of human injuries in the workplace. Although ergonomics does address the physical, cognitive, and organizational aspects of human interactions with work systems, ergonomics focuses more on efficiencies and risk to the individual, not all who operate within the system.  

Have a PEAR to better understand Human Factors 🍐

I’m not referring to a yummy piece of fruit. PEAR is an acronym that is used in the aviation industry to describe and better understand the application of human factors. PEAR stands for:

People

Environment

Actions

Resources

People: These are the individuals who perform work on the AOA. The demographics (age, sex, education level, physical abilities, mental capabilities, and etc.) of each individual must be equally considered as no one person is created equally to another. Have you considered the differences in personal communications between cultures? Human factors experts do. As mentioned above all aspects of the work and associated systems must be designed around the capacities and limitations of the people.

Environment: Environment ties into people as it represents the physical, social, and organizational environment the people work in. Runways are located outdoors, which is subject to extreme temperatures, noise, lighting, and darkness depending on where you live and the time of day. Most workers who access runway surfaces do so in some form of vehicle, be it a plane, tug, or car. The condition and use of the vehicle must be considered.  Organizational environment is directly related to the company’s safety culture and overall attitude towards working safe, just culture, accident investigations, and hazard abatement.

Actions: Actions include how well the employees are trained, certified, licensed, and made fully competent to execute the functions of the job task safely. Organizations who excel on actions keep excellent documentation of training, performance reviews, job hazard analysis JHA’s and job task analysis JTA’s. Tasks steps, sequence, communication standards, and quality of deliverables are all high priority items.

Resources: Resources tie into people, environment, and actions. Typically, resources can imply any item needed to complete a task. As mentioned earlier airport workers approach runway surfaces in vehicles. The vehicle can be both a working space (mobile office) and an organizational resource. The working space aspect will affect the employee’s environment. Does the AC work in the vehicle on hot summer days?   From the organizational standpoint the people performing a task are also a resource. According to the FAA, resources can best be measured by the amount of additional or less resources needed.

I have provided an overview of what the discipline of human factors is, and its relation to runway incursion avoidance. All too frequently airport safety managers fall back on lack of situational awareness as an incident cause. Same goes for airlines and the use of the term pilot error. With a strong understanding of what makes up human factors safety we can begin to explore further its application to avoiding runway incursions at airports.

Can you:

Determine how this knowledge can improve runway safety at your airport?

Think of any methods of identifying and controlling human factors errors for airport employees?

I look forward to hearing from you very soon!!!

Runway Incursion Avoidance Series 1 (Airport HOT SPOTS)

Runway Incursion Avoidance – Airport HOT SPOTS

What we know about airport HOT SPOTS 🔥

An airport hot spot is defined as a physical location on an airport’s movement area known for being high risk for the potential of creating a runway incursion or ground collision. Most hot spots exist at runway intersections and exit points. Typically, hot spots are areas of complicated design and bad airport layout planning. Pilots and ground vehicle drivers should use elevated situational awareness when entering known hot spots.

How to identify an airport HOT SPOT 🔥

History is always the best teacher. At your home airport, data from past surface events, accidents, and near misses can be telling to where problem areas exist in the airport movement area. For this reason, data integrity and collection of surface events is critical for airport management. When visiting airports, hot spot locations can be found on the airports diagram chart supplement.  An example of this is provided as the attached picture. Aeronav also produces a list of known airport hots spots as published by the FAA. This can be found here: All_Hotspot.PDF (faa.gov). In 2022 the FAA undertook a hot spot standardization project. This effort standardized the symbols and verbiage used on airport diagram charts to be consistent and less confusing. Today only two symbols are used to identify hot spots, they are either a circle or a cylinder.

How to reduce the risk of HOT SPOTS 🧯

Heightened awareness, knowledge, reduced exposure, inclusion, and training are all excellent suggestions to reduce the risk of an accident at a hot spot. Heightened awareness can be maintained by staying vigilant and always knowing your exact location and destination while driving or operating in the movement area. Knowledge ties into heightened awareness from utilizing experience from airfield driving and having a through understanding of the complexity and challenges of your airport’s layout. When I was an operations specialist, the hairs on the back of my neck would stand up when I approached a intersection with multiple entrance and exit points. Knowing the size and type of aircraft that operate on the airfield helps as well. For example, if I observed an aircraft with a Delta logo, I could speculate where it would park and its path. If the plane were a heavy, it would most likely go to the heavy departure runway, or parking gate at the terminal. If it were a regional jet, it would most likely go to the regional terminal or secondary departure runway.  To reduce exposure, hot spots should be avoided by ground vehicle drivers when at all possible. This is accomplished by proper planning and the use of alternate routes such as access roads. Never cross a runway or taxiway to save time regardless of if its closed. Inclusion involves participating in inhouse discussion and asking questions when necessary. My home airport host FAA sponsored Runway Safety Action Team RSAT meetings bi-yearly. These forums are excellent in identifying and declassifying a movement area surface as a known hot spot.  Training is something airfield drivers and pilots are accustomed too. As a safety manager and aviation professional, I’m all for spending time and resources on training. I want to highlight here the quality of your airports training efforts. Make suggestions, and think outside the box to improve training and never allow your training sessions to become mundane.

As mentioned, know, and avoid airport hot spots whenever possible. Always use a heightened sense of vigilance when in the area of a known hot spot. This simple advice can make the difference in preventing a simple operation from becoming an accident investigation.
