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.

Life in the 22nd Century

It’s not an original thought but science, and its advancement, is like a venerable oak tree. Roots spread over a large area, are not seen, but are critical to the health of the whole tree. Branches expand as the tree grows. Branches divide, some branches fade and others gain ever more strength. A tree that lives as long as a civilisation, ever changing.

I put this view forward only to admit that there are flaws with this way of thinking. For a start, in the past, a branch of science may have been pursued in a pure manner. Accumulating ever more knowledge on a specific subject. Now, the branches of science have become far more intertwined. Complexity is a given.

This makes a futurologist job harder. It’s no good to dream along straight lines. To see progressive development as the most likely direction. In the past, there was mileage in projecting forward along a clear line of thinking. Take for example the opening up of the atomic world. Futurologist in the 1950s imagined a world of limitless energy. Inexhaustible sources of electrical power that would be cheep and available to all. For good or ill, the age of plenty didn’t happen. That doesn’t reduce the importance of fundamental discoveries. It cautions us in extrapolating from a simple beginning to a fantastic new world.

What will life in the 22nd Century be like? I can say with certainty that I will not see the year 3000. Well, that is unless the cryogenics of science fiction stories soon becomes reality.

One approach is to look back 75 years. Compare and contrast. Then look forward 75 years. That is factoring in an acceleration in discoveries and the exploitation. And as I’ve alluded above not being shy of growing complexity.

This is again an approach to be taken with a fair degree of caution. Back in the 1950s there was talk of electronic brains, as the computer emerged as a viable and useful machine. What was imagined then is now quite different. That use of the word “brain” isn’t common parlance. Instead, the advent of so-called artificial intelligence is becoming everyday language.

Another set of cautionary factors are trying to guess the branches of the tree that will decay and fall. What seems promising based on current technology only to be bypassed by discovery and innovation. Here I’m thinking that the building of massive power-hungry data farms may be a technological cul-de-sac. Vulnerable and hugely expensive physical infrastructure that’s out of date the minute it’s switched on.

Each of us has a brain that weighs a lot less than a room full of cabinets of conventional electronics. Nature manages vast amounts of data without a power station in tow.

In the year 3000, I maintain we will have a rich and rewarding intellectual life. It will be different in form, although the things that amuse and entertain us may not be so different. The themes of a Greek play are still likely to be echoed in the stories of the next millennia.

Artificial intelligence will be a junk yard term. The whole of the world of data communication and processing will be hidden under layers of obscuration. It’s possible that a form of agent will be overseeing the mechanisms for providing the services we demand. The great challenge for democracies will be how to ensure that agent works for the public good. Not so easy.

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.

Aviation Insights

One shilling and seven pence, that’s what a copy of Flight magazine cost in 1960. Today, roughly that’s equivalent to £6. Which is not so far off the weekly cost of a typical printed magazine taken off-the-shelf in a newsagent. Now, Flight is a digital subscription[1] at £22 a month. We consume our News in a different way, but the overall price is not so different.

Spending money in charity shops always contributes to some good cause or another. Certainly, our British High Streets in 2026 are markedly transformed from that of 66 years ago. Fine, if I get hung up on that elegant number. It’s not a bingo call. It’s the number of times I’ve circled the Sun. Circled, that is, while safely attached to this rocky planet.

The young woman behind the counter was chatting to what must have been a regular when she looked up. I pointed an unregarded dusty box on the floor in the corner of the shop. “How much to you want for that box of old aviation magazines”. She looked slightly fazed. Nobody had even thought about pricing them let alone selling them. They had probably been donated as someone emptied the attic of their grandparents. Probably on the verge of going to the recycling bin.

Eventually, we settled on a modest price. She looked me up and down. I’m sure she thought that I was completely mad. That said, charity shop workers, volunteers, must face that colourful situation more than a couple of times a week. Even a day.

What struck me was the first inside page. The weekly editorial could have been written yesterday. It’s titled “Facing it” and reads thus:

“More than one great newspaper has given warning that our nation is living beyond its means – that our export prospects are poor, and that we are taking a commercial thrashing”.

“Bleak prospects for a people who have never had it so good, and one that promotes us to consider how the aircraft industry is facing up to cold reality.”

It went on to highlight that there had been few new aircraft at the Farnborough airshow of that year. It was an October publication[2]. There was a lot of talk about industry and Government cooperation but that this was not delivering.

“And now that the industry is needed, as it has never been needed before, it will not be found unready or unwilling.”

But the lament was about the failings of the Government of the time, and there being no room for complacency. This was 4-years after the Suez Crisis.

Today, we have an increased security threat, much as arose in the Cold War days. Industry and Government cooperation needs to be a lot more than fervent aspirations. We seem to be in the same phase of formulating strategies rather than implementing actions.

Don’t let me paint a picture of gloom and doom. What this Flight magazine had is great stories of British technical innovation. Electronics and control systems were advancing rapidly. Automatic landing systems were being pioneered. Technology applied improved aircraft performance and aviation safety significantly. In fact, in numerous areas Britain was not only leading, but guiding the world.

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 11^th 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.

The most important invention in your lifetime is…

A standout invention is one that is enduring. It’s celebrated. It shapes what comes next. It addresses an issue that’s been there for a long time. That just it – time.

I’m stretching the intent of the question a bit. Invitation doesn’t always have a single moment of realisation. Theory and experimentation come together to show promise. It’s latter that practical applications start to flow from that innovation. For me, the key invention is the beginnings of atomic time. The ability to measure time with precision.

Now, we know that past, present and future are the way we experience time. Not time itself. Having create clocks that gain or lose less no more than a second in billion years is an astonishing feat.

Today, a great deal of the infrastructure that surrounds us, and we hold in our hands, depends on precise time. Communication systems exploit it. We navigate using this asset. Society has been and will continue to be transformed.

Yet timekeeping systems have not reached their limit.

Visual Cues and Decision Making

Back to visual perception. Initially, it may not seem right to focus on one human sense and not discuss the others. We are multifaceted humans. The brain takes advantage of all its senses, when they are available. We’ve evolved with amazing capabilities.

The interesting notion that certain wines taste better when accompanies by certain music is a wonderful example of how interactive our systems can be. That’s without us having any conscious control over their immediate intimate workings. Parts maybe hardwired and others soft wired and adaptable.

Vision plays a dominant part in enabling us to move around. We haven’t yet evolved echo sounding, like bats and dolphins. This is not to say that those who loose vision can’t compensate to some extent, but they don’t fly aircraft or drive fast cars or become astronauts.

My thoughts arise from exposure to several aspects of our dependency on seeing the world around us. To begin, at the early part of my career, it was indeed the process of taking sound imaging and making it usable for recognising objects. Converting the information that come back from sending sound pluses through water into an image must deal with a dynamic environment. Interpretation of such electronic images can be the difference between hitting an object at sea and avoiding it.

Later, my design work concentrated on information presented to a pilot and what happens next. That whole arena of the aircraft cockpit is one big interface. The link between the senses and the decision maker. I’m not straying into the interminable debates about human factors.

Let’s stay with the trend that’s in front of us in every walk of life. That’s the dependence on recognising and acting on information that is presented to us on a nearby screen. In so far as I know, humans didn’t evolve with this need to relate acutely to closely presented information as much as reacting to distant stimulus. Afterall if a hostile animal or dangerously armed person was heading towards me at speed, I wouldn’t sit around debating the subject.

Aeronautics has experience in this shift of attention. At the start of my career aircraft cockpits where mostly knobs and dials. Mechanical indicators and filament bulbs. Sometime unreliable. Still the idea of flying by the “seat of the paints” prevailed. That centred around situation awareness, predominantly guided by looking out of the window. At the outside world. Distant vison equally, if not more, important as looking two feet ahead at a panel. Over the last five decades the above has changed radically. Instruments are large flat screens dotted with an array of colourful symbols offering every aspect of “situation awareness”.

Now, this is happening to cars. Most new cars have electronic screens. The expectation is that we humble humans have transitioned from simple mechanical dials to a fascinating world of colourful animated markers and whizzy logos. Despite the glorious technology the basic function remains the same. That is the link between the senses and the decision maker.

Adequate levels of visual perception being the number one attribute a pilot or driver is expected to maintain. This continues to be true as automation does more and more. What maybe a long-term trend in human evolution is that shift between the importance of what’s a couple of feet away and what’s in our surroundings. Will we become less sensitive to a personal experience of what’s more that two feet away? I wonder.

Future of Engineering

I do find it astonishing that back in the early 1990s I was still producing handwritten material that then got typed up by a typist. Then, were edits and errors needed correcting, “cut and paste” really meant cutting and pasting paper. Applying Tipp-Ex correction fluid was normal. Wonder who uses that now? It’s still available.

Engineering practice adopted word processing rapidly from that time on-ward. It’s now almost inconceivable that anyone would get someone else to type up their work. Early lap-top computers that weighted heavily on the shoulders, were carried to meetings as necessity but not love. The joys of trying to find a printer that would work was a daily mission.

In about 30-years we’ve gone from that primitive introduction to the digital realm to machines that want to write papers and reports for us. From brick like “portable” computers that required cables and batteries that drained in minutes to the complete world being available on-line anywhere on the globe.

The mechanisms by which engineering design and development were done have advanced in such a way as to make the past seem rather curious. I’m not saying that we’ve become ever cleverer and more inventive with the passage of time, just that the speed of trail and error has increased dramatically.

Past mechanisms did make the ability to change a path, once set on that path, difficult. I remember the reluctance to introduce changes unless an overwhelming case could be made. In this new situation, making changes still has a cost associated with it, but the resistance to change isn’t so much driven by the processes used.

What’s happing, like it or not, is that artificial intelligence’s transformative impact is touching, or will be touching, everything we do. That includes engineering design and development.

I’d say it’s a good time to be an innovator. In theory, it should be possible to explore many more possibilities that could be explored in the past. That is for the same level of cost in time and money. There’s not a single part of engineering practice that will not be impacted. Classrooms, meeting rooms and workplaces where the business of communicating technical ideas and testing them goes on, will be fertile ground for the application of AI.

I don’t think we understand just how transformative the impact will be on engineering. It’s not all upside either. Technology’s promises are great. There are perils too.

AI can only know what it’s been trained on. That maybe extremely extensive. However, innovation comes from creativity and inventiveness where the past may only be a partial guide. Also, there’s the danger of overreliance on these almost magical tools too. New skills must develop to be critical and knowledge of the deficiencies of complex algorithms.

All of this is a bit different from paper, correction fluid, scissors and tape. What an exciting time to be a young engineer.

International Collaboration in Space

It’s only taken 20,000 years for Homo sapiens to migrate to the American continent and then decided to industrialise the Moon. Just imagine what the next 20,000 years has in store.

Putting nuclear power on the Moon is a possible enabler for a future Moonbase. Considering the length of time it has taken since the last footsteps on the Moon, a Moonbase is long overdue. That said, going to a faraway place where there’s an abundance of solar energy potential it’s an interesting development that nuclear power is given a priority.

My view is that exploration beyond Earth is a matter for the whole of humanity. Going to the Moon should be an international endeavour. There’s good reason to cooperate when it comes to exploration. For a start space exploration is incredibly hard to do. Rockets explode with an unsettling degree of frequency.

Modern humans have gone from tens of thousands on one continent to what may top ten billion on Earth. It’s no wonder space, the final frontier, beckons. Trouble is we have evolved as specialist on this planet. Not well adapted to the space environment. If our wandering species is to venture into the void, we need to be mighty determined. This will be hard. The hardest effort ever made.

It would be absurd for individual nations to establish separate camps on the Moon. The space race is a concocted nonsense. More flag waving PR than serious sense. Why do I say this?

One: Demand on resources, to build, develop and maintain, a space presence is high. Sharing costs has benefits when planning for the long-term. Continuing costs can be volatile.

Two: In the event of the almost inevitable failures and setbacks, better to have partners to create different ways and means to recover or mount rescues in the worst-case scenarios.

Three: Partners can specialise. Not everyone has to do everything all the time. Afterall, that’s how our modern society came about in the first place.

Four: Cooperative planning means more gets done at the same time. Duplication and fragmentation of efforts don’t serve the great goal of exploration.

Five: Earth’s people are interconnected and interdependent. Even small Moon based colonies will inevitably be the same. Reliant on connections, locally as much as to a distant home.

As a spin off, making exportation an international endeavour can bring us together on this divided planet too.

What’s in a box?

I didn’t have a jack-in-the-box as a toy. Springing into life at the flick of a catch. For the larger part frightening the living daylights out of a young child. Or is it play, and thus basic training that surprising events can be scary and fun? Early days of leaning to handle risks.

In this case my boxes are square. Although they don’t need to be square. They are square or rectangular on a ballot paper (usually). These boxes are a boundary within which a mark is put to say “yes” this applies or “no” this is does not apply. Naturally, that can be the other way around too. For that matter they can indicate all sorts of conditions or views.

Here’s my beef. Back in March, this year, me and the Sun developed our relationship. There’s the giveaway – year. My number of years on Earth clocked up to sixty-five. At the time, I didn’t think of this as any more significant than past birthdays as a man of mature years. Then I got to completing numerous questionaries. Yes, I have moved the subject to more stuff to do with data and its use. Collecting data has never been so popular.

Never in the whole of human history have we, you and me, been faced with so many questionnaires. Almost every time I buy a coffee, and use a card of App to collect points, next day my in-box has an e-mail with a survey. Most of these I just ignore. Now and then, I fill one in with the ridiculous idea that the insignificant draw prize they offer could come my way.

Please offer your feedback in this short survey. The number of minutes they say that are needed are never right. Then they, the collectors of my data, get greedy. Asking for “as much detail as possible”. At this point I want to say – get real. What’s even worse is clicking on the “Next” button and then an error message comes up saying “This is required”. What audacity. Checky. Pushing my good will to its limits. If there were questionnaires about questionnaires, when it asked: “please tell us how your experience was on this occasion” they would get more than 100 creative words.

All this said, my real beef is to do with the collection of personal data. There’s no obligation to provide such data, when it comes to marketing surveys. This is when the incentivising possibility of a prize comes in. Afterall this data is valuable to the collectors with little incentive for a respondent to offer it. Surveys with prizes must have published terms and conditions. I wonder if anyone ever reads these legal niceties.

To the point. One question that often gets asked is – tick the box appropriate to my age. What I’ve noticed is that several of these unsolicited surveys have a box marked sixty-five and over. It’s like a whole section of the population is piled into one big bucket. Like we all fall off the end of the bell curve. Over 11 million people in England and Wales are like one.

I’m part of a growing cohort. That maybe good or bad but it is the case. It’s the case too that my cohort spends. Again, for good or bad, we are the beneficiaries of some good fortune. However, marketing surveys continue to sit in the stone age. At both ends of the demographic bell curve, toddlers and more mature folk, we are viewed as the same, one big bucket. I imagine data collectors and the designers of surveys have wrestled with this one. Whatever, the results don’t sit well with me.
