Getting the right amount of stimulation from your simulation: What role does fidelity have in training to fly? 

Full flight simulators are amazing tools for learning. Training devices have become more sophisticated, more true to the environment they recreate and, with this innovation, more expensive to use as well. But have these advances made them more effective as training tools in parallel, or is there a limit to the benefits of ever-increasing realism to the learning environment? This article aims to explain two of the key concepts in using simulated environments for training, fidelity and transfer of training, and invites you to consider the pros and cons of your own experiences of teaching and learning in the simulator.

Military vs Civil: Does training background affect safety in helicopter pilots?

Which system produces the better pilot – military or civil? Does it matter? According to a recent study of helicopter pilots from the University of Aberdeen with the title “Does training background affect safety in helicopter pilots?” (Kaminska et al., 2023), maybe we are right to be asking these questions. The answers suggest that we need to pay more attention to how the military-civil divide impacts CRM behaviours amongst mixed crews. What do the cultural differences embedded in the different ways these pilots have been trained mean to competency, operational effectiveness, and – ultimately – safety?

On helicopters, elephants, and training.

This is the elephant in the room that has been stubbornly refusing to move: very little has changed in how we train helicopter pilots for four decades or more. In the meantime much else has changed, but collectively we are unwilling – or unable – to make significant changes to what the training and checking system prescribes. Why is this? And what should we do about it?

Navigating cross-cultural turbulence: Why the multi-national complexion of aviation demands we should all add culture to our competencies.

Just mentioning the word culture seems often to be met with a glazing over of eyes. I learned that discussing ‘cultural capability’ in the military was unfashionable, uncool, and frankly unmilitary. I have a sense that the same is true in the world of aviation, which is ironic given the uniquely international nature of the industry…

Hindsight: blessing or curse?

Have you ever read an accident report, had an incident related to you, or sat through a CRM case study that made you say out loud something like:

“What were they thinking?” “Why on earth did they decide to do that?” “How could they not have known?” “They must have seen that coming, surely?”

If you have – and we all have – then you have fallen victim to probably the most powerful and omnipresent psychological bias out there: the hindsight bias.

A very normal accident

It was early evening on the 24th September 2022 when an offshore AW139 helicopter inbound to Houma-Terrebonne Airport in Louisiana, USA, declared a mayday. A lot had already happened in the cockpit by the time the co-pilot hit the press to transmit… 

We take a look at Normal Accident theory in the light of a recent accident: Technology is both a risk control and a hazard itself. The act of adding technology is at best risk neutral. Continually adding more technology in the belief that we are adding more layers of defence in a system is flawed because we are in fact adding more combinations of possible failure modes. In other words, there is a direct trade- off between increasing safety by adding in more controls, and decreasing safety by adding complexity.

Helicopter human factors in focus

“For no other vehicle is the need for human factors research more critical, or more difficult.” Sandra G. Hart.

That’s a bold assertion that I had never heard anyone make before and consequently had never given much consideration to whether or not it might be the case. So let’s unpack that proposition a little by looking at the arguments that the author offers to back it up…

The safety dividend of aviation’s professional culture?

How much does an aviator’s own cultural identification with safety have a role in contributing to safety outcomes? Certain professions have strong and distinctive professional cultures. Aviation is one of these. Does a belief in a deep-rooted safety culture underpin how aviators identify as professionals?

The need for speed? How slowness has a value all of its own.

Human exploits in aviation have always been closely linked to our fascination for speed. We admire speed in its many guises and it remains a marker of achievement in almost any field you care to think of. In aviation, just as in many other walks of life, we often assume the faster the better. We associate speed with competence. But what if we could disassociate the idea of slowness with incompetence? What if instructors were made to teach the opposite? What if we came to associate a slow response with higher skill levels and greater professionalism?

Developing resilience to startle and surprise in helicopter operations

Also published in AirMed&Rescue April 2022 edition. https://www.airmedandrescue.com/latest/long-read/developing-resilience-helicopter-operations

What should startle and surprise training mean in an applied sense and how should we be approaching it? Do the differences between airline transport flight profiles and helicopter operations mean that we should be looking critically at how to approach the startle and surprise from a rotary wing perspective? Is it as significant a hazard in the low level, high workload, high obstacle environment in which helicopter crews spend much of their time?

The automation explosion: examining the human factor fallout

Also published in AirMed&Rescue, Nov 2021 edition.

Automation reduces workload, frees attentional resources to focus on other tasks, and is capable of flying the aircraft more accurately than any of us. It is simultaneously a terrible master that exposes many human limitations and appeals to many human weaknesses. As we have bid to reduce crew workload across many different tasks and increase situational awareness with tools including GPS navigation on moving maps, synthetic terrain displays, and ground proximity warning systems, we have also opened a Pandora’s Box of human factors to bring us back down to the ground with a bump. Sometimes literally.

Distributed Situation Awareness

Pretty much everyone in aviation is familiar with the concept of situation awareness. But as research interest in SA grew, the concept expanded from the individual level to how SA might apply in the context of larger and more complex systems. What does distributed SA actually mean? The idea is that SA is held by both human and non-human agents. Myriad technological artefacts within a system also hold some form of SA. Now if, like me, you initially struggle with the idea that an artefact (such as a radio, or altimeter) can have ‘awareness’, then bear with me…

ARE YOU A SPECIALIST AVIATOR? WHY DEVELOPING RANGE IS PART OF YOUR JOB.

Photo: Lloyd Horgan Most of us will recognise amongst our colleagues that figure who has an unmatched knowledge of their aircraft and operational procedures but isn’t a natural team player, doesn’t share thought processes much, and just perhaps doesn’t quite integrate with the rest of his/her colleagues as comfortably as others. We admire technical knowledgeContinueContinue reading “ARE YOU A SPECIALIST AVIATOR? WHY DEVELOPING RANGE IS PART OF YOUR JOB.”

On Lookout and helicopters

The importance of an effective lookout. We’ve heard it from day one in aviation, a constant through our flying training days and beyond. The dangers of mid-air collision, obstacles, and controlled flight into terrain (CFIT) will always be there.  These are not static threats however, but are always evolving. Take the proliferation of drones asContinueContinue reading “On Lookout and helicopters”

Flying SAR in the sunshine: What’s not to like?!

From the Atlantic to the Mediterranean: The Weather. Learning to adjust. And just learning. On moving to Valencia last year to try my hand at flying a Search and Rescue helicopter in Spain, the predominantly anti-cyclonic picture of Spain’s Mediterranean-facing east coast presented an entirely new meteorological situation to me. “SAR in the sunshine, what’sContinueContinue reading “Flying SAR in the sunshine: What’s not to like?!”

Is Human Factors in aviation at a crossroads?

Now seems like a good time to look beyond the dark prism of the current COVID-induced crisis in aviation to consider a future beyond the mire. The Chartered Institute of Ergonomics and Human Factors (CIEHF) recently published a White Paper called “The Human Dimension in Tomorrow’s Aviation System”. It’s made up of a series ofContinueContinue reading “Is Human Factors in aviation at a crossroads?”

Aviation safety culture and the paradox of success:  Can safety innovation keep pace with technological progress?

The aviation industry is hailed as a pioneer of safety practices, of open reporting, of just culture, and in learning from its mistakes. And given its remarkable safety record, this reputation is perhaps justified. Nevertheless, it would be both complacent and counter to those values themselves to believe that the goal of safety has alreadyContinueContinue reading “Aviation safety culture and the paradox of success:  Can safety innovation keep pace with technological progress?”
