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.

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.

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.

Lessons from Operational Events

For an aviation industry that takes pride in learning lessons from experience and taking timely corrective action, a series of operational events is surprising to say the least.

Today’s large aircraft do look much the same. The tricycle undercarriage has become universal. A set of steerable wheels at the front and a heavy set of landing gear, each side, to the rear. When parked, a nose gear collapse or inadvertent retraction on a large aircraft is not catastrophic. The aircraft can be recovered, inspected, and repaired. This undesirable event can be dangerous for anyone in the vicinity. It has the potential to be fatal. Fortunately, so far, there has been no fatalities.

For an aircraft operator such an event at an airport gate is a massive expense. Putting an in-service aircraft out of action for a considerable time.

To date, several damaging nose gear collapse (and alike) events have occurred to large aircraft[1]. Detailed analysis of these events exists and corrective actions are proposed.

One conclusion is to say that this is about people not following procedures. That is the instruction is to put a pin in one place but instead it gets put in the wrong place. So, this dramatic unintended event is written up as a maintenance error. It’s an outcome that no one intended. That’s fine. There’s no doubt that an error was made. Accepting that an error occurred is not a reason to blame. That is if there are no signs of negligence.

The trouble is the simple question – how easy was it to make that error?

Then we get into that grey area of the gap between aircraft design and operations. In a design office it may be reasonably assumed that a procedure will be followed in an almost robotic manner. No need for the people in operations to think beyond taking the same action day-after-day. This would surely become widespread practice.

As we know the actual environment of aircraft operations can be more demanding than the original equipment manufactures might imagine. Pressure to turn around an aircraft can be high, working conditions can be poor and fatigue can play a part.

There are lines of communication between the aircraft design and operations organisations, and such difficulties are regularly discussed.

Faced with an event categorised as maintenance error then what next? Redesign the aircraft? Change a procedure or require more training? Those are three of the options, there are more.

This is where the possible discussion gets reactive. Now, it would be extremely costly to redesign an aircraft for the sake of an event that is rare or for which the consequences are minor. It is possible to put numbers on each of these. The rarity, the cost, and the impact.

Modifying or rewriting a procedure, on the other hand, can be less costly and it may be quite sufficient as a corrective action. That said, any procedure that can be written can be subject to error. In fact, the original procedure may have been straightforward and well thought out.

Then there is the fall-back position. Give the people in aircraft operations more training. The assumption being that more training means less errors. It is a crude assumption because this is not a linear relationship. So many other factors come into play.

Discussions surround the above possibilities can become protracted. There’s a call for more analysis and more data. There’s the proposal for a study to be conducted. Once in that loop a year can go by as if it was a month.

There’s always the argument that highlights dozens of aircraft operators haven’t had this event occur and therefore the finger is pointed at those who have. This argument gets an outing, but it is foolish. It’s like saying – I haven’t had an accident yet, and therefore I’m safe. Foolish.

There are a lot of detailed discussions and a million and one opinions. Taking the big picture, this is a problem that is solvable[2]. What is surprising is the reoccurrence of the problem.

Modern Polymath

It’s easy to conclude that there’s no such thing as a polymath in the 21st century. So expanded is the field of human knowledge that no one person can have a sufficient overview of every academic, cultural, political, and economic discipline. Not only that but the ability to articulate concepts and ideas in an understandable manner.

If I were to think of a classical polymath, I’d instantly go to American Benjamin Franklin. It’s even how he is described in literature. Here, I’m going back to the 18th century. In the multimedia age, there are numerous influential intellectuals who have become spokespersons for their discipline, but none stride across a vast range.

We segment and partition knowledge, and pepper it with dedicated terms, that it’s way more than a human head full. Specialisation is both a curse and a God send. Generally, the intensification of study of each and every subject has been a bonus to human progress.

There’s become an excess in manipulation of language to suite each scientific endeavour. That goes for politics and economics too. Particularisation does tend to create distance between those who dig deeply into specific subjects.

To help unravel ingrained complexity there’s a respectable number of writers and YouTubers who try their best to communicate. If anything, the demand for this skill is increasing as we move from the traditional paper-based publications, say New Scientist, to the myriads of social media platforms. Then the issue becomes which one speaks with authority.

I started this piece with a thought in mind. It really was to say something complementary about the BBC. Yes, a media organisation that gets a fair share of criticism, but the world would be a much poorer place without it. Its roots are deep.

A popular British pastime is quizzing. That has played a part in TV and Radio since they were invented. A quiz is both entertaining for the participants and those who look on. Like a modern-day mediaeval tournament, a display of quick thinking and astonishing depth or range of knowledge. A test that allows us all to take part even if we come away all too aware of how little we know. Not so much unsettling as a quick return the earth.

Is there’s no such thing as a polymath in 2026? As an avid watcher of the BBC’s University Challenge[1], I’m struck by the breadth of questioning and the ability of the teams of students to find answers to the most tortuous questions. Obscurity knows no bounds.

On questions of famous paintings, I have a preprogrammed response. It’s either Titian or Tintoretto. It’s surprising how many times that works. Try as I might, I rarely get into double figures however much I guess. It’s always worth a punt. Sitting in the back if my memory are facts that I’ve no idea how they lodged there over the years.

Watching the winning teams of students, I do wonder if the notion of a polymath is dead. It does restore my faith in the infinite variety of human capabilities. This counteracts the fancy marketing blurb that accompanies machine learning software. Practically, humanity is far from becoming obsolete.

Navigating Change

It’s all too easy to say – it was different in my time. How things have gone downhill. There’s a boring refrain from me, and my baby boom generation, which laments a lost era. What we forget is that all of history is a lost era. Becoming history is a discomforting feeling.

I remember walking around the transport museum at Brooklands in Surrey. Look to one side and there was an aircraft cockpit display that was the latest tech in my days as a young design engineer. It was slightly worse than that in that the retired equipment, covered in dust, was one I worked on in the late 1980s. Sophisticated at the time. Now an item of curiosity.

This weekend, I stood under the last flying Concorde at Aerospace Bristol. Looking up the supersonic aircraft, it remains stunning, impressive, and futuristic. It’s a real testament to the British and French engineers who were so adventurous, creative, and foresighted in its design.

That said, in the end that era came down to money and politics. Just goes to show what the implications are of having made a robust international commitment and finding it impossible to backout. As a purely business adventure, a project like Concorde is difficult to justify. As a cultural icon and industrial marker laid down for all of history to appreciate, it’s momentous. It’s reasonable to say that the success modern-day AIRBUS has roots in this tremendous European collaboration.

Anyway, back to war and more day-to-day concerns. There’s no doubt that having some form of industrial strategy is better than not having one. The trouble is that UK Governments come and go and are incredibly fickle. So, a nice policy document with sound ideas can either spur change or slowly gather dust with equal measure.

Reflecting over the last 40-years and more, the UK has taken a large peace dividend. Defence spending has declined steadily under every political flag. This has led to a focus on fewer engineering projects. A concentration on fewer prestige assets whether in the air, at sea or on land. A gradual cutting of cloth to fit a lesser role in the world.

How do I write is without the predicable lament? It’s a matter of highlighting the downsides of the current position without lapsing into an archaic wish for a return to a bygone era.

One observation I would make here. If I pick up a British aviation magazine of the 1960/70s it’s clear that there’s a huge diversity of small and medium sized enterprises (SMEs) making products that are as diverse as they are spread across the country. Yes, the large aerospace companies have consolidated so that there remains a handful of prominent names. A lot of the iconic British names have disappeared. Consigned to museums. Inward investment has meant that the titans of the past have been swallowed up by international businesses.

There’s a pattern here that is not uniquely British. I’d make the point that one of the most concerning weaknesses is the decline of the large ecosystem of SMEs. Or the precarious situation that is often their fate. These businesses are the smaller fish that swim around the bigger players. They have the capacity to be dynamic and innovative. Even if they are often under regarded and more vulnerable to economic shocks.

Central government can’t always solve problems. That said, they can, at least, take an interest and create an environment where such entrepreneurs can flourish. Reflecting over the last 40-years and more, governments have been immensely ineffective in this respect. Policy documents are great. Where the failing persists is going from words to effective actions.

Transport of Flight Delights

Air Taxies are becoming a reality. It’s not Science Fiction anymore.

The history of the “hackney carriage” is along and illustrious one. They remain firmly attached to the road. They do move with the times. From horses to combustion engines to electrified cabs[1], I wonder if London back cabs will adopt Hydrogen fuel next?

Providing safe and reliable public transport for about 8-passengers, in reasonable comfort, with a limited amount of luggage, they are a vital part of the city landscape. Ferrying people from place to place and even going south of the river (a popular saying from the people who live north of the River Thames).

In New York, “Yellow schools of taxi fishes” in a song by Joni Mitchell. Schools or sholes of taxies swimming in a sea of traffic. Frantic and colourful as they are shown in a lot of 1970s movies. A chaotic scene where the protagonist runs out into the middle of dense, barely moving traffic.

What happens when these modern convinces take to the air? If they were still with us, I’m sure Flanders and Swann[2] would have written a song about this new marvel. The distain of London buses towards black cabs is there in the lyrics. So, as air taxies take-off, as it were, will the cab drivers of the city protest or join the ranks of new flyers?

Please don’t answer that question. I’ve in mind more serious issues. The whole history of aviation safety data analysis shows us an immutable fact. Take-offs and landings are riskier than flying in at altitude. It really matters not if flying horizontally or vertically.

How does this come to be? A simple answer would be to say that the results of aviation accidents eventually end-up on the ground. Gravity does its work. Put that aside for a moment. Take-offs are optional but landings are mandatory. That’s a traditional saying that amuses non-flyers but is all too real to pilots and alike.

The act of taking a flying machine from the freedom of movement in 4-dimensions to a preselected stationary point on the ground. Those policies and plans that are published refer to Vertiports being established much as Heliports have been in the past. Some may double up. The theory is good. A pre-defined clear space that can accommodate a typical eVTOL aircraft used as an Air Taxi, with all the necessary operational and safety provisions. Surrounding areas protected from the down wash of the Air Taxi. Care to remove any foreign objects from the vertiport surface. A mini terminal to add to the cityscape.

One of the biggest variables in this brave new world of public transport is as old as the hills. It’s the local weather. Dubai can roast an aircraft with clear skies and 50C while Aberdeen can soak them in rain and impenetrable mist. Dust and wind can blow through Marseilles while deep snow and ice covers Montreal. Whilst in Lahore the air itself can be hazardous.

Terrestrial vehicles do cope. Often this means that there are different rules and regulation that take account of the local conditions and priorities. The impatience that some advocates have for a rapidly formulated globally set of harmonised rules and regulations might be misplaced. In fact, it may even impede the introduction to service of Air Taxi services.

Since I’m discussing the busy urban environment, I can presume that any accidents and incidents will be the focus of a great deal of public attention. Ultimate safety is a nice aspiration, but then reality takes hold. There will be occurrences. When they happen, city councillors are going to have their say.

FLANDERS & SWANN – ‘A Transport of Delight’ – 1957.

Determinism in Aviation Safety

The arrow of time. We fly from past, to live in the present and anticipate the future. Sir Isaac Newton would be proud of us. By unravelling laws, that where always there, the means to anticipate the future was illuminated.

In civil aviation, we have devised and grown a whole regulatory system that depends on learning from the past, doing calculations today and flying with a belief that we know what’s going to happen next. Flying is predicated on a reasonable degree of predictability. There’s clear logic in this way of thinking. Just imagine powering up a couple of massive jet engines and starting a take-off roll without being extremely confident that at a certain speed the laws of physics will do their part and the ground is left behind.

We don’t establish a reasonable degree of predictability by looking at a crystal ball or taking up alchemy. Yes, we do still depend on reasoned expert opinion in addition to doing calculations. The minute those expert opinions start to shift away from grounded reasoning and careful deliberation then danger is afoot. This is one of the arguments for treading carefully when political opinions start to come to the fore. The laws of physics are not established by a public opinion poll. Nevertheless, it’s equally polarising to say that there’s no political dimension in the aviation regulatory system.

Anyway, that’s not the subject that was on my mind. Conversations about Artificial Intelligence (AI) are more prolific than those about self-help books. Even the shelves of popular high street bookstores are starting to fill up. The non-fiction titles with AI, either as the main subject or as an adjunct are numerous. It’s the fashion to write something literate or purely speculative.

I’ve mentioned the word “determinism” before. It can be interpreted philosophically or in a more scientific and technical manner. Determinism is a belief in the inevitability of causation. That chain of cause and effect that is so familiar to anyone reading an aviation accident report.

Understanding what causes something to happen in a moment in time goes back to my initial subject of a reasonable degree of predictability. In aircraft certification, no matter how complex the system, when presented with a system safety assessment we expect a comprehensive and reasoned set of statement. Predictions about the “what ifs”. What if an aircraft part fails and what happens next? What happens in combination with other failures?

This is where AI is potentially problematic. All the reasoned arguments in the world go out of the window if a system, subject to the same conditions, behaves one way on a Monday and differently on a Friday. Not to mention the weekend. I could say, AI is remarkably human in that respect.

The subject that was on my mind is not the inner working of complex aircraft systems. Certification experts are on that one. It’s possible to put boundaries around the behaviour of some aircraft systems. What’s more fascinating is the evolution of AI interactions with us mere mortals.

Let’s say I have the responsibility for return to service of a transport aircraft that has been subject to maintenance. A pile of documentation will provide the evidence that the work conducted has been correctly completed. It conforms. Amongst that paperwork might be an output from an AI driven diagnostic system that flashes a green light to say everything is fine.

Now, playing with the “what ifs”. What if it’s not fine given that the conditions experienced were way outside the AI systems training and it does a creative hallucination. The person signing the release to service documentation would have no idea or facility to question the green light. But it’s their signature that matters in the process of return to service.

There is a point of concern.

The Future of Driving

What next? There’s a growing number of Electric Vehicles (EV) on the market. In fact, the diversity of choice doesn’t make choice easy. Such a variety of different sizes and configurations. Cars big and small. Hybrids too. Every new generation offering more range and more bells and whistles (technology).

My car is getting near to its 11th birthday. It runs exceptionally well. Trouble is age, ware and tear, can’t be escaped. Bills start to ramp up as millage takes its toll even if it hasn’t done – yet. German engineering isn’t always what its cracked up to be except my car does fit the stereotype. Temptation is to buy another one.

My first trip to the US was back in the early 1980s. Four of us drove up and down the west coast. Seeing spectacular sights and meeting amazingly friendly people. American cars of that time were of the Cagney & Lacey generation. Meaty metal boxes that handled like a crate of jelly. Gas guzzling but, who cares, gas was cheep in comparison with European prices.

Wide empty roads, outside the cities, where the landscape filled every vista with new wonders. City driving wasn’t so pleasant. Freeways where the occasional Blues Brothers like police car buzzed past at speed. Air quality dropped a million percent (exaggeration). Jams in more lanes than we’d ever imagined possible.

So, are Electric Vehicles (EV) the spawn of the devil? I take the point that not everything is as rosy as the marketing departments of the manufacturers would have us believe. Some prestige models are bulky and heavy. These are not well suited to the narrow pothole heaven of England’s poorly maintained roads.

That said, the change is upon us, and it would seem foolish to go backwards. Once over the initial purchase price, which does seem to be coming down, EVs don’t cost much to run. There’s a simplicity of electric motors which a high-performance reciprocating engine can’t match. Not only that but high-performance reciprocating engines have probably reached the limits of what can be squeezed out of them. Decades of development in reducing tail pipe emissions.

It’s clear Electric Vehicles (EV) have a long way to run. Battery technology will continue to improve. That’s one to bet the house on. It’s because there are so many applications for high power density batteries. If you are aiming at a Nobel Prize in Chemistry, that’s the way to go.

Driving a car with no tail pipe emissions does have a holier than thou feel about it. If we want cities to be healthy places to live, then something must be done. I wouldn’t want to live near the world-famous Hanger Lane Gyratory[1]. Or anything like it. In England we built massive road systems on top of streets designed for the horse and carriage.

Looking at new cars, like the Mercedes-Benz CLA[2], I must admit I’m tempted. Putting that up against the lumbering thundering rust buckets of the 1980s and there’s no comparison whatsoever. Whether it’s sheer performance or climate change that motivate a purchase decision, the days of conventional petrol and diesel cars are numbered.
