Safety – John Vincent

Patch?

Hobbyists built it. So, how come billions are invested by the huge corporations that use it? Only a fraction of their resource was used to create it in the first place. The INTERNET is as much a wonder of the world as the pyramids. I don’t say that lightly. Today’s level of interconnection, intercommunication and interaction across the whole globe was merely speculated about 50-years ago. In historic terms that’s the blink of an eyelid.

Where we are now it’s impossible to imagine a future without the facilities that are at my fingertips. Tap out recognisable words and they can go anywhere, everywhere, or nowhere.

[That part is poor. Keyboards are where my fingertips connect with the world. Surely there will come a better way in the not-too-distant future? Evolution didn’t make us this way.]

Looking at some other major advances of civilisations, they came about in separate ways.

Long distant roads were originally military assets. Getting legions of troops from one place to another in a sprawling empire. Dominating the landscape. Reinforcing even the most remote outpost. Crossing a great distance on land has moved through several phases, waterways gave way to railways and they back to roads, as a primary means of transportation.

The telegraph was more, what I might call, can do technology. Experimentalists like Marconi put two and two together to make five. Scientific investigation provided the possibilities. He, and his like, were entrepreneurs. They saw the piece parts of technology as a business opportunity.

Aviation was more of an evolutionary advancement. A dream that the ancients held and wrote about. Slowly down the centuries theories and experimentation came together until powered flight became viable. Then decade after decade, more technical possibilities were exploited. Warfare, enterprise and adventurers have driven continuous development.

The INTERNET wasn’t seen as a commercial opportunity at its inception. It was a put together simply as a means for scientists to share their work. Maybe more than hobbyists doing the work but technicians with no master plan for world domination. They certainly were not Bond villains.

That is one possible one reason for the vulnerabilities inherent in our global electronic infrastructure. This week, the implications of those intrinsic vulnerabilities are becoming all too apparent. Embedded code that only a few experts take any notice of, that is until something bad happens. Their vital work never especially celebrated or significantly rewarded.

I don’t say it will ever happen but what if there was a practical plan for an INTERNET-2. A whole new set of protocols? An attempt to build-in integrity, expandability, and security from day one. Learning from experience.

The word “patch” is an indication of how crazy the current situation remains. It’s like that silly word “glitch.” Even the word “junk” seems quite inadequate if a crook “hacks” someone’s private account. These words make serious issues seem like minor inconveniences. Distinguishing between annoyances and harmful situations has become muddy waters.

Why is this the case? Is this the only way to communicate what’s going on.

I think it goes back to simple utility. Is the INTERNET, in its current form, so incredibly useful that society can tolerate any number of “inconveniences.” I wonder. Or will the story be like the waterways and the railways. Neither will ever go away but one will dramatically improve on the other. Push past the other. Thus, civilisation advances.

Qualitative and Quantitative

Do I need to define these two? Yes, because they are not words that automatically come up in everyday conversation. Not even in technical conversations.

A qualitative approach to an argument deals with words, meanings, and experiences. Not so much opinions but defensible objective judgements based on best available information.

A quantitative approach to an argument deals with analysis, numbers and statistics. A scientific approach rooted in believable evidence that is reliable, repeatable, rational deduction.

In the aviation safety world, we use both. It’s my view that one is not subordinate to the other. However, the persuasiveness of one is greater than the other. At the end of the day, persuasiveness matters. If a key decision is to be predicated on an argument, then how it is constructed and presented matters a lot.

Many is the time when I have sat in a room listening to a person make a case in as elegant and enthusiastic a way that they can, but the results have been less than impressive. I’ve made the mistake myself. Coming prepared with a barrage load of sound evidence accompanied by a flaky presentation that misses the mark.

That is why the order needs to be thus. Establish a qualitative argument supported by quantitative information. Not the other way around.

In the field of aircraft system safety assessment this is vital. Probabilistic analysis is a powerful tool. Relating numbers to human experience is not so easy. So, detailed charts and logic diagrams sprinkled with numbers are unlikely to be enough on their own.

Stating an objective is met by handing over a pile of calculations is half the job. However impartial and truthful the numbers may be, arguments are not made until they are explained.

Many is the time when I have lifted a large report from my in-tray, studied it and concluded that there’s something missing in that gap between the QED and the statement of compliance.

Maybe this an element of safety regulatory psychology. It’s difficult to approve something if it becomes difficult to explain to others what’s been done. That evidence trail needs to be explainable. And easily explainable to a wide audience.

This doesn’t change with digitalisation. Replacing large piles of paper with large files of results puts the reader in the same position. Impenetrable evidence needs understandable explanation. Presenting a qualitative argument supported by quantitative information is a good way to go.

Unraveling Future Risks

Much talk of the end of times doesn’t make for the end of times[1]. It’s true to say that commentators have taken time on their keyboards to ponder on the apocalypse. It isn’t the first time the subject has occupied the public mind. I could say that the four horsemen of the apocalypse have been around since biblical times. They have, and now there’s a couple more of them riding around the globe.

In my lifetime, the atomic age, the jet age, being wiped out by bombs and a following nuclear winter was brightly coloured there on the chart of probability. Far too high up that chart. Then the Cold War ended and a period of moderate sensibility seemed to exist. That didn’t last long. Chewing over the masses of accumulated planetary climate data created another headache. This time, but at a slower pace, climate change became one of the horsemen. No doubt the popularity of apocalyptic science fiction and science reality comes from a deep insecurity. A realisation that the evolution of space and time is way beyond human control.

Playing my vinyl that’s been sitting in a box for too many years, I’m listening to one of my favourite David Bowie tracks. “Five Years[2]” is the ultimate apocalyptic disaster song. It asks the listener to imagine the News coming over that we’ve only 5-years left on Earth. What would happen in such a situation? Would we all scream and run around like chickens with no heads?

Now I must ask, is that a good lead into one or two words about Artificial Intelligence (AI)? Those working on this technology seem to be getting nervous about that technology which they have cherished, developed and promoted. Let’s first say that AI is not new. When I graduated, in the 1980s, it was one of those esoteric subjects that was only for those wanting to do a PhD in an obscure part of the world. Not more than 20-years ago, given that aviation research was part of my remit, academics lobbied me because they thought a complex neural network should be able to predict the next major accident in aviation. That is fed with enough safety data. They may have been ahead of their time.

What has surprised a lot of people is the speed with which industry has gone from academic research to live digital systems that exhibit astonishing abilities. Access wide open too.

I don’t know if there’s a Moore’s Law[3] for AI. There doesn’t need to be one. The observation is that every week there’s News of even more powerful technology being made available. The disruptors are disrupting themselves before the rest of us have a clue what’s happening. As David Bowie would sing: “my brain hurts a lot.” Here’s what I think is problematic.

One. Concentrated Ownership. This innovation, and its potential power are in the hands of few people and States. Specialised expertise and infrastructure are prized intellectual property.

Two. Forecasting Dilemma. Projections are fuzzy, to say the least. Who can be believed? A simple curve on a graph doesn’t cut it. Step transitions are more than likely.

Three. Sleeping Sentinels. Regulatory lag is normal. Rules and regulators take time to mature. It’s just that, in this case, this lag may be disastrous. And some prefer to sleep.

Four. Legacy Thinking. Imagining AI’s future to be a version of past progress is woefully inadequate. It’s a new game when machines exceed human intelligence.

I do not believe that the world will end in five years but it maybe unrecognisable from today’s world. AI will create as many problems as it solves. Surely the powers that be need to step back and think about how the next decade will pan out.

Digital Age Dilemma

There was a time when most of the political parties in the UK would object to mass surveillance and the State having a watchful eye on every one of its citizens. The influence of the Magna Carta, that 800-year-old document, was a keystone of thinking in this country. Although it was aimed at the privileged when first placed in front of a Monarch, it embraced the idea of liberty. It so upset the establishment that a Pope denounced it.

Ideas endure and those contained in the Magna Carta went on to inspire the framers of the constitutions and legislation in many countries. It doesn’t sound so strange in modern times that a person should be able to go about their lives without an overbearing State impinging on their liberty. Well, at least in theory.

I remember the intense debates that took place in the mid-1990s. The subject being the introduction of identity cards in the UK. Technical arguments were made of how such a measure would simplify lives in the coming digital age. Those agreements paid little attention to the erosion of fundamental rights that the centralising personal data on citizens would bring.

What’s happened now, through a process of stealth, is that people have given away vast qualities of data to international commercial entities without batting an eyelid. The legal device that has been used is a contract that few people ever read. The End User License Agreement (EULA). This detailed fine print addresses data collection and aims to protect software providers from liability.

I suspect that Conservative politicians have observed how little attention people are paying to the erosion of their rights that they feel emboldened to abandon any commitments to liberty. For some time now the Conservative mantra of has been to leave the European Convention on Human Rights (ECHR). This is based on a gamble that most people will not have read the document. It’s a bit like the snatch and grab that the typical EULA has become.

Now, the Conservative Party has doubled down on a shift to the right of politics by inviting the prospect of mass surveillance. There’s a reasonable argument for the police to excurse powers to delve into the digital world when investigating crime. In fact, how can they not do so. However, this should be done so when there’s reasonable basis for doing so. Not everyone is a suspect of criminal activity. The law of the land still upholds the idea that guilt must be proven.

Computational tools are getting ever more powerful. I could joke that the number of articles on AI would reach to the Moon and back, but I wouldn’t be far wrong. One of the powerful software tools that’s accumulating uses is that of digital facial recognition. We’ve advanced from the days of inky fingerprints, although such prints are still valuable identifiers.

Where do we have a problem with liberty? The framers of many longstanding constitutions didn’t have to think to hard about what liberty meant in a world devoid of digital cameras. Now, any citizen’s image is going to be caught hundreds of times through the day. Maybe thousands of times. That instant image can be present on storage devices across the globe.

Who owns that image of me or you? Can it be used by anyone? Tricky questions given phones, traffic cameras, doorbells and home and business security cameras are subject to EULAs. On a superficial basis, requiring police forces to extract digital images and run them through a national database can sound like a good crime fighting idea.

The problem is where is the line drawn? Mass surveillance? Where everyone is an immediate suspect until proven not guilty? Not guilty by virtue of the calculation of an algorithm. Widespread digital camera coverage does put this in prospect. Images stored all over the world. Do we need to reframe the Magna Carta for the AI age? Now, there’s a thought.

Doorway Effect

Without question, there’s one experience every person on Earth has from birth to death. That’s unless they are completely motionless. I should clarify. I’m not talking about basic body functions. Eating, drinking, sleeping, and breathing. Let’s say, there’s one experience every person on Earth has in a built environment. Even of the most rudimentary kind.

The impressive ones are huge. Ages ago the common ones were typically smaller. Their use is instinctive. The experience of their use can range from impenetrable to completely transparent.

[Today’s most written about movie has a wide selection of them on show. One of them pivotal in the crux of the story being told. It was penetrated and the course of a war changed.]

Minutes ago, I got up from my chair and walked into another room. I went there with the distinct intention of doing something. By the time I got to the other room, I’d completely forgotten the reason I went there in the first place. It’s took a moment’s double-take to realise my original intent. Then normality was restored. I assure you, this is not an eccentric quirk of mine alone.

Doors do that to people. For a start they are unavoidable. Every construction we’ve ever built must have a means to get from one place to another. A basic part of our human needs is shelter.

In my 1950s house, and that of most other people, they are standardised products of an industrial society. Each with a style and colour that suites its location. Each with a consistent mean of operation. Components manufactured from across the globe. A technical discussion could get incredibly wide ranging, as to the variety of ancient and modern doors. Hinged, sliding, barn, pivot/revolving, swinging/saloon, roller, flush, up-and-over, louvered, or trap doors to name a few. I’ll steer clear of this minefield.

What’s intriguing is the impact doors have on us. Transitioning from one place to another is way beyond a simple physical process. The mind is engaged in movement. Not only the shape and form of the environment but how it changes. A whole plethora of mental processes click into action as we go from A to B.

Starting at the primitive. A calculation we make concerns safety. Is there a threat either here or there? Most of the time this consideration is subconscious. In extreme cases it’s the one overriding consideration. A good reason to read the safety card when sitting on an aircraft.

What struck me this morning is the annoying reality of forgetfulness. It’s a part of life. Yes, there’s the factor of age. This is not the sole factor by a long way. My focus here is on the short-term impact and not a severe one at that. The simple fact of passing through a portal increases the likelihood of a momentary loss of some part of short-term memory. I wonder why?

Here’s an off-the-chuff theory. It’s to do with safety. In going from one environment to another the mind is preparing for whatever might be encountered. Doors by the nature obscure what’s on the other side. Fine, that’s not always true. An open gate, a kind of door, may not hide the path ahead. Whatever, there’s a transition in prospect. A need to process new information on the “other side.” In anticipation of having to process that new information the mind rationalises what it knows. Is my mind saying, now I’ve gone from A to B, I don’t have to bother so much about some of the stuff I’ve left behind.

Well, look at that. The “doorway effect[1]” is in the scientific literature. Me being me. I wonder if there any implications for aviation safety. It could be said that some people, often alcohol induced, leave their common sense behind has they enter an aircraft door. More seriously, evacuating during an incident, does it matter that short-term memory might be impaired?

Future of Aviation: Enhancing Safety and Resilience

The aim is clear. A safe, secure, sustainable and resilient international aviation system. I’d add to that list an ambition to continuously improve.

And that’s in the face of the challenge that was recognised 30-years ago. With an aviation system that knows how to archives a high level of safety, even incremental improvement is challenging. Factor in projected air traffic growth that’s unabating. What we know is that that continuously improving the global accident rate requires active interventions.

Since here I can only highlight the key priorities, I’ll choose three aspects of active intervention. Back to what I said earlier in my talk. Aviation is still climbing a maturity ladder. Digitisation has facilitated a growth in proactive work. Initiatives and plans identify actions aimed at solving known aviation safety problems. But the next step remains some way off. It’s that ability to anticipate safety problems before they occur. To predict.

We have the notion of safety intelligence. There are Big Data projects that are gathering large quantities of aviation safety data. Today, what might be called prognostics continues to depend on expert judgement. That’s not negative, as such. In fact, that augmented by objective and trustworthy safety intelligence is a route to the next step in maturity.

In my view, here’s the three categories that must be addressed now and, in the next decade.

One is a foundation stone of aviation safety work. It’s the capability and will to react in a timely manner to events. Not just accidents and serious incidents but any event that elevates aviation safety risks above acceptable levels.

Top operational risk that are likely to need immediate actions are those involving loss of control and those concerning runway incidents.

To take timely corrective action the results of investigation need to be readily available. As pointed out by the industry, across the globe, there’s much scope for improvement here. Timeliness matters.

My next category is that of systemic risks. System wide safety risks. People, organisations, processes, procedures, the human factor and human performance issues.

Much is being done to ensure the effective implementation of safety management systems (SMS). The four pillars of SMS have proven to work – safety policy, risk management, safety assurance and safety promotion.

The acceptance, elimination or mitigation of risks is not an act that begins on one day and stops on the next. Digitation can help but there’s always the dangers of the needle in a haystack or even problems sitting in plain sight.

What’s often weak is the communication of what’s discovered. Believable, understandable straightforward communication to decision makers is vital.

Thirdly, what’s ahead of us is an order of magnitude more complex than what’s gone before. And a rate of change that mindboggling.

I’m calling this emerging aviation safety risks. The question arises; are we ready for advanced leaps in technology? Hydrogen, hybrid propulsion, machine learning, quantum computing, complex airspace networks and robotics. Humans as executive manager whilst retaining control only in emergencies.

It’s a famous quote; data is the new oil. We are ushering in extremely large and complex datasets that will be essential to the workings of automated and autonomous systems. Could data be the new quicksand? This is a huge issue in dense airspace where crewed and uncrewed aircraft must share the airspace.

Another emerging aviation safety risks, that industry and regulators are starting to address is the fact that safety and security have become inseparable. In the past, these disciplines were addressed as silos. That’s no longer viable.

Another emerging aviation safety risk is that of the workforce. Aviation has attracted dedicated professionals who acquire experience and train to a high level of competence. A safety culture has been embedded. In this respect the fundamentals of aviation safety remain constant.

The rapid growth of technology is a two-edged sword. Now, there are many opportunities for future generations, but aviation may not be at the top of the list of choices, as it has been. There’s a serious aviation safety risk if serious investments are not made, people are not motivated and able to gain the competencies needed by a rapidly changing industry.

To sum up. Everything I’ve spoken of can only be addressed in partnerships. In the past, the aviation industry and its regulators have proven themselves to be imaginative, resilient and forward looking.

The challenges ahead, dare I say, are even greater. Levels of integration, interdependency and rapid technology adoption are off the charts. Yet, I believe we can continually improve global aviation safety. We can step up.

POST: Farnborough International Air Show 2026. 20-24 July 2026.

Current State of Aviation Safety: Data-Driven

The present day. Today. There will be Press Releases galore at this air show. I expect ambitious and upbeat predictions. More orders. More growth. More developing markets. Demands for more skilled people, more performance, more pressure for the early adoption of rapidly changing technologies.

My subject is safety. Where are we with aviation safety in the present day? There’s a sound legacy. Afterall aviation has a long tail. What we have now, and if I look at the Farnborough Airshow catalogue of ten years ago[1], is digitisation. The ambition to be data-driven. A continuing drive to exploit data of all kinds. Extracting information from ever increasing sources in aviation.

This desire for actionable safety intelligence is not new. On my desk I have a coaster celebrating the UK CAA’s MOR Scheme[2]. That’s been alive for 50 years (1976-2026). Occurrence data has been, and is being, used to construct all sorts of safety performance indicators. These indicators can be useful but it’s not always so. They are fuel for safety management systems.

I used the word “actionable” with purpose. Today, making the results of safety data analysis useable by front-line actors and responsible managers has been a challenge we wrestle. I’ve often heard it said – that’s great but what do I do about it? Too many “greens” on a chart and complacency can set in. Too many “reds” and everyone goes into panic mode.

I have been fortunate to work with a number of safety initiative. One called the Commercial Aviation Safety Team (CAST) in the US. To match its work, on this continent, I set up a European version; ECAST in 2006. The focus was on data-drive analysis. There’re safety teams for Rotorcraft and General Aviation too.

These safety initiatives came about a reactive way. Reporting in 1997, the Gore Commission, was a reaction to dilemmas that is still with us. What to do in the wake of catastrophic accidents. And more pertinent to this talk; what to do when the global accident rate curve looks flat at the same time as predictions are for a significant growth in global air traffic. Reading this report now, the predictions were horrifying. Predictions of one large aeroplane fatal accident every week by now. Luckily, commercial air transport didn’t suffer that fate.

I should NOT say “luckily”. Current safety performance is down to an enormous amount of work done by thousands of aviation professionals over a sustained period. Not only this but shocks, whether they be financial crisis, volcanic eruptions or global pandemics, have tested this industry severely.

Taking on board what was learned over the decades, safety management has developed and matured. Incorporated in aviation’s safety regulatory framework, it’s now practiced across the whole industry. Almost. We don’t just react. We now have Safety Plans. Lists of actionable tasks aimed at continuous safety improvement. On the scale mentioned earlier – we are proactive.

Let me stop. This is not a utopia. I’d say at least half the global aviation industry is struggling with the need to be proactive. So, the road we are travelling on remains a long one. We don’t just need the capability to do better; we need to maintain the will to do better.

The Evolution of Aviation Safety: A Historical Overview

A quick tour of the history of aviation safety. In a couple of minutes.

As powered aircraft took to the skies it quickly became apparent that, of all the means of transport, aviation was less forgiving than others. Moving at speed in four dimensions, with the necessity to take-off and land safely, has inherent risks. By no means does this mean that flying is an dangerous activity. What it does necessitate is an exercise of sound engineering, preparation, and proficiency. When these are missing, and in cases of misfortune, accidents and serious incidents happen.

In the days between the world wars, aviation moved from the military and a circus-like amusement to a viable means of public transport. Progressively, more passengers had the opportunity to experience the wonders of flight.

Today, it’s not the early days of flight I want to focus on, but we do owe the engineers and aviators of that time a great debt. Much was learned as aeronautics matured. Since the end of the second world war the production, promotion and application of standards has embedded what had been learned. This has established the way that international civil aviation works.

One simple expression of the stages we’ve been through is Prof Patrick Hudson’s[1] model. This model describes five distinct levels of cultural maturity. The steps are pathological, reactive, calculative, proactive and generative.

This model sits alongside steps in the development of technology that have been a hallmark of aviation. Different categorisations exist. AIRBUS[2] has one that’s easily understood in terms of generations of civil aircraft.

First are the “classics” of the 1950s and 60s. Next, the second generation starts down the road of more electronics. More safety critical systems. Third generation starts flying in the early 1980s when automation becomes the norm (early fly-by-wire, glass cockpits, flight management systems). The fourth generation introduces safety systems, which address the major causes of fatal accidents, namely Controlled Flight Into Terrain (CFIT) and Loss Of Control In-Flight (LOC-I). That’s the early 1990s. When I made that move from industry (design and production) to an aviation safety regulator.

Now, I’d say we are well into fifth generation aircraft, with composite structures and integrated modular avionics. In fact, we are well into speculation about what the sixth generation may look like. Machine learning, single pilot operations, hybrid powerplants, aircraft as a node on a network.

Because aviation is a learning industry, and a conservative one, the expectation is of progressive improvement in maturity throughout the aviation system and innovative technology applied to enhance safety.

This is not to say that the potential for error, missteps and recklessness don’t exist. They do. I expect continuity in a way that takes full advantage of advanced methods without scarifying the legacy of an astonishing good global aviation safety achievement.

Later, to cover a lot of ground in a short time, I’m going to condense all the above into three distinct categories. But before that, I’ll talk about the present and a vision of the future.

Public and Private Life

What’s public and what’s private? There was a mythical age of the past when the dividing line between these two was self-evident and sacrosanct. Wholy respected by every member of society. A time when an Englishman’s home was his castle. Anything that happened within it’s walls was not for prying eyes or journalistic speculation. Everyone knew their place.

Naturally, this is utter nonsense. At least described in the way I’ve put it. Times change. Those immortal two words. So, the line between what’s public and what’s private has wobbled around over the centuries. I’m not, as you might expect, saying that nothing has changed over time because a hell of a lot has changed. Now, there are factors that make the public life different from past decades. Themes run through the ages along with unyielding change.

It’s very much in the News now. The impression given is that the act of standing-up in public has risks that can be high. Not so much the traditional risks of humiliation, being ostracised or suffering abject failure but real risks to life, in a physical sense.

It would be ridiculous to say that these are more violent times. When I look out of my kitchen window, I am reminded of the English Civil War[1]. Father and son, brothers, uncles, and cousins fought on opposite sides with fatal consequences. The ruined castle on the hill to my North is a monument to that terrible bloody conflict. In the lifetime of my parents the bombs fell from the sky on innocent civilians in this land, as they do in Ukraine to this day.

The tendency to think that we are a much more civilised society in the 21^st Century is a liberal and progressive notion. We are better fed and read. There are greater comforts and the four horsemen of the apocalypse are kept at arm’s length. Not disappeared but kept in check. Although the recent experience of COVID did unsettle everyone for a while.

What we do cherish. I hope we cherish, in this country. Is the relative freedom of speech that allows debate to be conducted in public. I use the word relative because the absolutists, who have an anything goes attitude, are not what I mean. Fundamentalist often ride with the four horsemen. Words do matter.

I’m straying from my point. There’s great merit in protecting public life. In matters that are of fundamental importance individuals must be free to stand-up and say their piece. Stifling debate is like putting the heat on a pressure cooker without a safety valve.

I’ve always been struck by the civility of most people. That’s what I’ve found when knocking on doors during political campaigns of one form or another. There’s a core of decency at all levels of society. Now and then, that thread is broken. It does take a lot to paint a different picture. That’s where the proliferation of social media has changed the dynamic.

The printing press was not an evil invention. That didn’t stop it being used for evil ends. The same with social media. Printed media is subject to regulation. A system of regulation that has developed over decades. That doesn’t stop a wide range of views being expressed. The fertiliser of public life. Similar boundaries are set for broadcast media. This is civilisation.

To date, social media is the wild west. It’s become essential to public life. At the same time, it’s a grave danger to public life. When it’s used to stir-up passions that lead to violence the danger is self-evident. Social media is not sacrosanct. Regulation is essential.

Digital Dependency

Here’s a collection of annoying and sometime hazardous events that can happen in our digital world. Digital dependency is growing at an ever-increasing rate. There’s no way we can put our head in the sand and pretend it’s not happening. Yet, I’d say we are ill-prepared for the stuff that can go wrong. Well, anyone over the age of 25 years can be ill-prepared. Maybe the younger ones are ill-prepared too because of the immense trust they place in digital systems.

Last night, the wonderful “smart” TV that sits in our living room behaved in a way that is designed to get anyone’s back-up. Ironically that’s the function that is often missing – back-up.

Do I blame my clever Sony digital TV or the App that’s running on the TV? The many Apps. Anyway, the TV guide displayed but every time a selection was made the TV screen went blank. Me being used to troubleshooting, I tried another App. All worked fine. So, only one App was misbehaving. Ony one App was not doing what it should do.

To most people this would be a shout out to say; my TV is broken. How can it be broken it’s nearly new? It’s not performing its most basic function. To me, my deduction was that the App that provides the digital stream of the live broadcast channels was doing some kind of update but, unhelpfully, not telling anyone about it. The dumb thing is that the screen went blank. No information. Why the developers of this App couldn’t have thought ahead and put up the screen words saying – please wait – I have no idea. Perhaps they like to see our blood boil.

By the way, the above event happened just at the end of a world cup football game last evening.

Believe it or not, this irritating blank screen case has occurred in flight on an in-service aircraft. The main displays in the aircraft cockpit blanked. For those who may not be familiar, the main critical flight information is displayed to pilots on electronic screens in a modern aircraft cockpit. So, when everything goes blank it’s not a nice situation. Because safety is the primary concern there are independent standby instruments. They are only basic and aimed at managing the situation.

The case that I’m writing about above was because of a notorious software error. One that’s by no means new. Most serious and well-trained developers will know the case.

Do a little maths. Have you ever taken any number and divided it by zero? For fun, I picked up a desk calculator, yes, they still exist and did this simple sum. The makers, Casio have that one figured out. A small E comes up on the corner of the screen. E for error. Trapping this potential error is elementary best practice. For flight safety related systems, it’s vital.

What’s my message? It’s to understand what it means for something to be broken.

A vast swath of the population continues to have a, learned from experience, idea of what broken means. It’s basically an analogue notion. If I get a puncture in the wheel of my car’s tyre it’s visible, it’s understandable and it’s fixable. It’s a physical phenomenon.

If my super-duper mobile phone does something strange and unexpected, it might be visible, understandable and fixable but it might not be. In essence I have few ways of knowing. I hesitate to introduce the subject of Wi-Fi connected computer printers to this short article, but I will. Some of the most frustrating, unhelpful and mysterious software has been developed for this equipment. Annoying to a level that is difficult to match anywhere on Earth.
