100% of accidents have Human Factor: mindFly

Contributory role of Humans Factor


Humans, by their very nature, make mistakes. Human error is implicated in 70% to 80% of aviation accidents. (O’Hare, Wiggins, Batt, & Morrison, 1994; Wiegmann and Shappell, 1999; Yacavone, 1993).

My views

I beg to differ with the basic premise. Human involvement in the chain of events leading to an accident is a fact. There is a 100% involvement of humans in the error chain. Elimination of error is not feasible. Human factors are about designing systems that are resilient to unanticipated events.


Crew resource management is a training intervention for threat error management. The whole focus has now shifted to error reduction. The human factor is a scientific discipline that requires years of training; most human factors professionals hold relevant graduate degrees. It is a myth that Human factors consist of a limited set of principles. As a result, the concept of CRM cannot be learned during a brief training.

Holistic view

Human factors work is not just limited to the individual level. Most importantly, HF also ranges from individual to organizational levels. As a result, it can bring other potential contributors. It can examine how the performance and safety of individuals and teams are impacted by organizational policies and procedures.


Human factor training needs in-depth study. Similar to learning the skill of flying, the same applies to the principles of human factor.

IndiBlog score of 63/100, no comparison with academic results: mindFly


This is the sixth month of blogging and Indiblogger powered by Alexa ( Amazon) has given me a decent score of 63 from a range of 1-100. I am delighted and quite excited. mindFly is a unique blog which mainly focuses on human factors in aviation. 100% of aviation accidents and incidents have the human factor as a contributory cause. The need to have a holistic view of human behaviour can help address the issue in a more pragmatic manner.

Thank you readers for the support and hope to develop an interactive blog in times to come.

What does my IndiRank mean?

It’s like runs in a game of cricket – the higher the score, the higher ranking you have. Blogs are ranked on a scale of 1-100.

How is IndiRank calculated?

A blog’s IndiRank is calculated based on various factors. Other blog ranking systems rate how popular a blog is. We’ve taken it a step further based on how deserving a blog is of becoming popular. This is to ensure that the lesser known, but well deserving blogs are pushed up the ladder as well. IndiRank will be completely refreshed every month, so a blog’s previous rank will have no bearing on it’s present rank.

What are the factors which affect IndiRank?

We’ve combined several factors including Google PageRank, Incoming links and alexa ranking (Inspired by the research done by Binaryday). Recently, we added mozRank as an important factor. The system also checks to see the frequency at which a blog is updated, and three other secret ingredients. Some of these factors have more weightage than the rest.

Moscow flight attendant switching modes, service to safety:mindFly


The primary duty of a flight attendant is to ensure the safety of the passengers and other crew. The cabin crew of the Aeroflot flight UA1492 is being hailed as the heroes. AFA Commends Heroic Aeroflot Flight Attendants on Flight 1492. The Association of Flight Attendants-CWA (AFA), representing 50,000 Flight Attendants at 20 airlines, mourns the loss of Flight Attendant Maxim Moiseyev who died on the burning Aeroflot 1492 aircraft while trying to save lives.

AFA President Sara Nelson released the following statement on the accident:

“Flight Attendants are aviation’s first responders. Flight Attendant Tatyana Kasatkina ‘grabbed passengers by the collar’ to evacuate people as quickly as possible. The crew were all heroes and our union will honor their action through official recognition. We offer them any support we may give as they grapple with this tragic event. We will also ensure their horrific experience and the lessons from it are never forgotten.

In an emergency, there is no time or room for being polite since every second count. The flight attendants who have been extremely courteous till the event, have to rapidly switch mode to being autocratic and ruthless in the interest of safety at large. The certification requirement of every aircraft requires an evacuation demonstration. All passengers have to be evacuated in 90 seconds from the time a command is given assuming only half the aircraft exits are available, others assumed to be blocked.

During a demo, the actors are briefed and are motivated to beat the target time, whereas in real life, each passenger has her/his mind occupied with a hundred thoughts and there could be a big chaos inside the cabin.

A380 Passenger evacuation demo

As you can make out from the video, the amount of preparation to beat the 90-second rule is enormous. The actors are briefed and they understand the criticality of performing as a group to qualify for certification. This is nowhere close to real life scenes that have been witnessed.

Training and training alone is the key to habit formation. This will help the crew to modify their behaviour to suit the needs of the situation. Safety systems and devices have to be built to have more practical rather than theoretical approach. Past evacuations have proven that there is an urgent need to address this issue.
