The Mystery of Flight MH370

It’s ridiculous and shocking. In the modern era of civil aviation, that a large passenger aircraft can go missing and never be found. This tragic disappearance that has had experts baffled.

Mysteries, in the early days of flying, were not commonplace. They were, however, sufficiently commonplace for pulp fiction writers and amateur investigators to fill their boots. Mysteries at sea, and in the air have been a fascination for as long as there has been maritime and air transport. As our scientific and technical capabilities have increased so has our expectation that these mysteries are of the past, not the present.

Without any cause for concern, Malaysia Airlines flight MH370[1] took off 12-years ago. The aircraft disappeared from radar and has never been seen since. Parts of the aircraft have been recovered. Unfortunately, those parts provided insufficient evidence as to where the whole aircraft crashed. With what is known, this Boeing 777-200ER[2] aircraft is somewhere in the depths of the ocean. How it got there, wherever there is, and why remain unknown.

The most recent sea search for the wreckage of the aircraft has yielded no findings. Systematically searching the Indian Ocean, an organisation known as Ocean Infinity, has not advanced our understanding of what happened to flight MH370. That might be unfair, since we now know that the aircraft wreckage is not likely to be at the locations they searched.

The vast area of the Indian Ocean has an average depth of over 12,000 feet. Locating an object on the seabed is a hard task even when there’s some idea where it’s resting. To make the task even more difficult, ocean seabeds have a wide variety of geological formations. Mountains, crevasse and flat expanses.

We spend most of our time living on dry land. The reality of planet Earth is that a larger part of its surface is covered with water. That we can be thankful for given what we see of other planets.

Thus, the importance of having the mechanism for location that works anywhere and everywhere. Airborne Communications, Navigation and Surveillance (CNS) is vital in all aspects of international flight. Flight MH370 was equipped with Boeing’s FANS-1 (Future Air Navigation System). This does have a surveillance function in that it provides aircraft position reports via satellite communication (SATCOM).

[In the late-1990s, I was involved in the standards setting and regulatory approval of the airborne components of both the Boeing FANS-1 and AIRBUS FANS-A systems].

Reports of the loss of MH-370 say this aircraft system was working at the point of take-off. Official reports also say that this aircraft system was “deliberately” disabled during the flight. A mystery remains as we may never get to understand the motivation for this action.

There’s no good reason for disabling such systems unless they are presenting a hazard to the aircraft in flight. Clearly the crew need to have the ability to isolate aircraft systems in the event of an avionics bay fire or other significant failure events. Circuit breakers are provided for that purpose. Procedures and training are too.

So many questions. Will the Indian Ocean search be revived again? Not for a while, I think.

Integrating for Success

It’s almost as if there’s two types of humans. Who often find it difficult to understand the other. In the field of pros and cons here’s a sketch.

One who takes a general overview that can be called the “big picture”. They shy away from dense information. Much in favour of short précis and a well-crafted pitch. Not so much interested in how an answer was derived as what it is an how it impacts their interests.

Another who specialises and focuses on precise detail. Deeply engrained in the working of a particular issue. Open to a continuous round of investigation and discovery. Not so much interested in an outcome as the interaction of the components that produced an outcome.

With the first, they are comfortable with ambiguity. A degree of vagueness. They can short-cut to decisions to provide a sense of certainty. On the downside this can lead to turning a blind eye to difficulties and failing.

With the second, they are obsessed with the pursuit of excellence almost to the exclusion of practicality. On the upside they may anticipate problems. Providing workable solutions before they become forced.

What am I talking about? Most people don’t fit in either camp. Or we have subjects where we dig deeply and others where we skim the surface. I’ve used the analogy of a basic comb on this one. The spine of the comb is the overview. The prongs of the comb are the deeper scrutiny.

My message is simple – both are needed. That is, both are needed to understand what’s going on. Where the subject is a complex aircraft systems design both are essential.

There’s another way of saying this too. Slightly different because this way assumes a hierarchic organisational structure. For the most part, despite fads and fashions to do differently, most large organisation still have a form of hierarchical arrangement. Directorates, departments, sections, teams and alike.

One view of a complex system can be taken “top-down”. Another view is taken “bottom-up”. Phrased like this (top and bottom) it’s not easy to appreciate that both are equally important.

As an illustration, I certainly remember working with highly professional engineers with incredibly detailed knowledge of their part of an aircraft. However, they had little idea of the implications of some functions in relation to the abnormal operations of an aircraft in service.

Equally, to be fair, those meetings with capable and highly experienced managers who were inclined to bypass or belittle difficulties to ensure that a promised date was met. Or an inability to appreciate the necessity to consider the long-term consequences of a finding.

My message is simple – the two perspectives must be drawn together for success. Bringing together the points of connection between the nitty gritty detail and a wider appreciation is a hard job. Fraught with misunderstanding the people who can do this are rare and precious.

The above is a reason to be concerned when the approach to efficiency is biased towards automation. To speed up design processes to get all the ducks in a row. To more quickly pile up the paperwork, or its digital equivalent, without time to think. Without the space to use our most valuable skills – experience, creativity, imagination, discussion and mutual respect.

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.

From Daedalus to Artemis

Being in good company is always nice. That spirit of experimentation doesn’t suite everyone. Now, I find myself in company of a NASA astronaut and an 12th Century English Monk. All in one week.

I stumbled across the NASA App[1] last evening. I hadn’t reckoned at that being available on my smart Sony TV. There it was. So, it only seemed right to download it and check up on what’s going on with the current Artemis mission. Other News told of delays and troubles with the launch vehicle that’s to send astronauts to circle the Moon. Setbacks are common in space flight so that’s not an issue to be alarmed about.

[Whatever would we do without the Ancient Greeks. Artemis, Apollo, Mercury, Gemini[2]].

This is a fundamentally important space mission given that it’s the first-time humans will have ventured so far since the days of the Apollo missions. Sending four astronauts around Earth’s satellite is a hard task to undertake. It’s aimed at establishing a means to get to the Moon on a regular basis.

Apollo spacecraft did this journey when computers were relatively primitive machines. Artemis has the advantage of a technical capability that is many fold greater. The problem is that sheer complexity and society’s tolerance for safety risk has moved on since the 1960s.

Anyway, the tale told, in interview of one of the Artemis astronauts is one of jumping off a barn roof as a young lad. Constructing a homemade parachute and trying it out. Having that freedom of a life growing-up on a farm and that appetite for experimentation. I was thinking, been there, done that and lived to tell the tale. In my previous scribblings I’ve mentioned the large red Dutch hay barn that was part of my youth.

Back to the Greeks. It’s myth but there may have been an element of truth in it. A map of modern Greece makes it clear that the islands of Ikaria and Crete are separated by a great distance. So, suggesting that a father and son in ancient time flew from one to the other can’t be true. However, that doesn’t dismiss the possibility that the Greeks experimented with the possibility of human flight.

So, the myth goes, Daedalus was the design authority for a method of flying which does not come recommended. Strapping on wings made of wax and feathers is a 100% risky venture. Daedalus was, if a real person, an imaginative ancient inventor. An inspiration to others. In this century it’s best to interpret the famous myth of flight as one of experimentation in a way that is fully respectful of the risks involved.

Coincidentally, this week, more by accident than intention. It’s a long story. I visited the town of Malmsbury. Inspired by the story of Daedalus, Monk Eilmer of Malmesbury[3] has solid claim to be the first European to fly. It wasn’t an entirely successful flight, but it was a flight. In the 12th Century he leapt from a church tower with wings of his own invention and survived.

Monk Eilmer of Malmesbury did end up with broken legs and a place in history. It would be unwise to repeat his early experiment as an example of human flight. That is unless a crude glider was replaced by four rotors, electric motors, some electronics and a powerful battery.

I share the hazards of a technical ability. Luckily my youthful attempts at flying with a parachute made of black polythene sheeting from a red barn roof didn’t result in any broken bones. Good luck to all who fly. Especially those who travel the furthest.

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.

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.

The Digital Dilemma: On Youth

Every modern technology challenges us all. Technologies’ relentless path is unstoppable. Technology inevitable is a two-edged sword (good and bad). Not everyone will accept these statements. This is my observation of the last 50-years in the UK.

1976 was an incredible year. It’s being celebrated as the year of Punk Rock. That’s just one snip out of the scrapbook. In fact, the music scene was over briming with diversity in that year. Low-cost microprocessors were coming on to the market. Forward thinking innovators, like Sir Clive Sinclair[1] were thinking about how to put these into the hands of everyday people. Trade Unions were signalling concern that this technological revolution would mean the loss of millions of white-collar jobs. Politicians ran around in fear of a severe threat to the established social order.

Let’s just say, there was no less a public clamour about how to react to the transformations that were coming down the road as there is here in 2026. What is a 16-year-old to make of all this at any time? I was 16 in 1976. Now, what’s it like to be 16 faced with current relentless and often troublesome pressure of social media?

That’s one phenomenon that I didn’t have to deal with as an energetic engineering apprentice with the thrust for speed and motorcycles. That said, all the stuff we hate about social media, bulling, harassment, intimidation, hurt, and suffering were still ever present in society.

My starting point is that banning things is to be avoided if there’s a better way. It’s profoundly illiberal to reach for the law to ban as the only approach to problem solving. My caveat. If there’s evidence of systematic harms being caused to a vulnerable population then a ban may be inevitable. In this I can cite the restrictions that are placed on young drivers and motorcyclists. Without legislation restricting activities our society cannot accept the resulting death toll.

Age limits are part of a civilised society. So, a dilemma exists. What level of harm triggers a ban? That is assuming that an enforceable ban is the most effective way of achieving reduced harm. In reality, a ban by law does not aways work. Either people find a way around it or it turns out to be unenforceable. It can also become smothered in processes and procedures to be rendered useless. Exceptions and qualifications.

How about banning mobile phones or social media for young people? That’s two quite different moves.

Mobile phones are part of the digital landscape. No one should go through future education without a necessary exposure and grounding in the digital world. It’s their world. It’s not going away. Social media is different, but it’s a nebulous product. It’s not so easy to sit down and write a useful and workable definition of what’s included in social media. Even if a law is written about social media, within a brief time it will turn into something different. It’s a combination of communications technologies.

What we do need is regulation to minimise harm done. That needs to be agile but comprehensive. A most perplexing task. Up until now, regulation is the digital realm has been ad-hoc and focused separately on application areas. Much more work is needed.
