Transform of Future Careers

My education was an industrial one. I guess I was fortunate. No “A” levels for me.

Part of my apprentice programme was to move around the different departments of a major electronics company. That included a range from demanding technical areas, testing new designs, to the everyday pressure of a print room run by an ex-Army man who ran it as if he’d never left the Army. Yes, print rooms were once a staple part of an engineering company. Huge dyeline machines that constantly ponged of ammonia twinned with the noisiest dot-matrix printers ever made. I even got to learn some COBAL[1] with the business unit that put together our payslips. Amazingly enough I was introduced to mathematical concepts, like Fast Fourier Transforms (FFT), at a time when the digital logic needed to implement such algorithms consisted of large cabinet loads of discrete electronics. Now, my simple mobile phone can crunch numbers in this way.

Several weeks here, and several weeks there. One excursion meant spending hot summer days in the Mendip Hills at a quarry testing equipment in deep water. Another meant time working in a former brick-built railway shed that served as a small machine shop.

Of all the different experiences that I had in those formative years (16-18 years) the one that I’ll never forget was a secondment to a London based factory. The company’s training officer recognised that this small village country boy needed to go to the big city. Uppark Drive, Ilford no longer exists as a manufacturing plant. That’s no surprise. In the late 1970s that factory handled the company’s long-lived products. Technology that has gone forever.

Anyway, this is not so much about me. What I’m led to speculate about is what sort of modern-day engineering apprenticeship offers. Does it offer the variety of experiences that I had? Is industrial sponsorship as generous and altruistic as it once was? Do industry and government work hand in hand to ensure a future workforce has the skills that are needed?

Simply the answer is probably “no”. In fact, the structure and organisation of design and manufacturing organisations has changed dramatically. In aerospace there are some companies that have a major factory with every facility at their heart but most subcontract extensively. Colleges have been turned into educational shops, paid by student numbers.

Here’s a thought. It’s not so much what’s taught that’s key as much as the exposure to a variety of ways of thinking and working. A variety of exposure give a student a toolbox from which they can then draw. Finding interesting work will depend on adaptation and repurposing past skills. That’ll be the only way to assure the world doesn’t pass by at an ever-increasing pace.

I’m sure that advances in artificial intelligence (AI) will affect everyone[2]. The idea that all AI will do is displace people is wrong. It just means that, like my recollections above, the types of activities that needs to be done will be entirely different in 2065. Unless I’m highly unusual, I will be long gone. But if you are 25 years old this is worth a thought.

Who 15

As per tradition there was a moment of running down corridors pursued by robots. Add to that the shock horror realisation that it’s bigger on the inside than the outside and the staple diet of BBC Science Fiction is playing again.

Dr Who is rolling[1]. As expected, Russell T Davies works magic with a super-fast story line. In fact, so fast that I’m going to have to watch it again to figure out exactly what the featured rift in space and time did to the plot. Thematically up to date as the main baddy in control of the evil robots was both misogynistic and AI. I’ll give something away if I reveal that the two letters AI were not what they seemed. Not only that but the robots were redeemed.

Although there was a smidgen of absurdity and an expectation that the audience would draw of decades of Dr Who mythology, the show hit the mark. Afterall it’s entertainment not a profound reflection on the state of the world. It’s colourful Saturday night drama that the whole family can watch. Although in this case there was no need to hide behind the sofa. Also, a lot of the 21stC social commentary would be lost on younger viewers.

Because the series has been running for such a long time there’s a bit of repetition that creeps in. This is not bad per-se. It’s a reminder that coming up with truly original scripts is incredibly hard. Imagination has no limits but when pen hits paper past references helps move stories along quickly.

Adventures in space and time could go on forever. All time, in fact. The subject has no limits. Each version of the Dr Who saga will be set in the context of the audience’s everyday reality. So, the Daleks were a product of nuclear war, and now humanities greatest threat comes from billions and billions of electrical ones and noughts.

Playing with humankinds’ curiosity about space and time is fruitful territory. Imagery can be fantastical and push the boundaries of video production. If anything, Dr Who is modest in pushing at those boundaries. Mustn’t forget that it’s prime time entertainment. Real space and time are far more than a headful.

Tragic Helicopter Crash

The record of sightseeing helicopters is not a good one. In the most recent case 6 people perished as helicopter crashed into the Hudson River in New York City. It’s with a heavy heart that I offer my condolences to the family and friends of those involved. These are devastating events for all concerned.

It’s certainly far to early to say why this helicopter fell from the sky. Eyewitness reports suggest a catastrophic occurrence. Also, that the helicopter tumbled and hit the water inverted. Again, suggesting an occurrence where the pilot had no opportunity to avoid the outcome.

Initially, the indications are that the local weather was not a significant factor in the accident. Also, reports are that no other aircraft was involved. In this fatal accident the US National Transportation Safety Board (NTSB) will be on the scene as they manage the technical investigation. They have already published initial information.

Given the size and nature of operations there will be no Flight Data Recorder (FDR) installed on this helicopter. There is a strong argument for requiring light weight flight recorders on small helicopters. It will be interesting to read of what electronics are recovered from the accident site. Images from a mobile phone may be most useful to the investigators.

The helicopter’s maintenance records will be reviewed for indications of mechanical problems. However, it is highly unusual for a complete rotor system to fall apart in flight. Mechanical failures often have some precursors that give an indication that all is not well.

The list of Bell 206 type helicopter accidents and incidents is long[1]. That’s not an indicator of their relative safety. This is a popular single engine small helicopter with a long history. Both civil and in other variants, military. First flight dates to 1966. It’s going back a while, but I clearly remember a sightseeing flight I took on such a helicopter back in the 1980s.

This type of small helicopter is often operated in difficult conditions. They have the advantage of being highly maneuverable. However, there are maneuvers that can case serious problems. The term “mast bumping” was used by the US Army[2]. In the worst cases this results in catastrophic occurrences.

One of the factors in such accidents and incidents is a significant change in the helicopter’s center of gravity and an inappropriate response to that condition.

POST 2: Pictures of the recovery of the rotor system from the river suggest structural failure. It’s as if the rotating mechanical parts ripped themselves from the body of the helicopter. Bell 206 L-4 helicopter crash, Jersey City, New Jersey (April 10, 2025) | Flickr

POST 1: Social media is littered with theories, as per usual. One seems highly unlikely. Namely, fuel exhaustion. Another, concerning a strike of a flock of birds over the river is worth investigation. In that possible case evidence will surely be easily uncovered.

Unlocking Prosperity

“So, whatever you wish that others would do to you, do also to them, ………”

This is the code of reciprocity. In other words, I’d like you to be generous to me, so I’ll be generous to you. Now, of course this works the other way around in a perverse way. Perfectly human, although it’s tainted with suspicion. I’d like you to be generous to me, but I think you are unkind, so I’ll be unkind to you.

I don’t think that’s what Apostles had in mind. Their teaching is first to urge us to be generous as a way of encouraging others to act similarly. A lot there depends on how you view human nature.

For a long time, the United States (US) has had relatively low import tariffs based on adopting a leadership position. It’s to say, you should be like us. If you do that, there’s a chance that we will both become more prosperous.

Generally, argue how you will, as a result the US has become the most prosperous nation in the world. I know it’s only one measure but looking at the numbers of billionaires by country 2025[1] the US stands out. Over a quarter of the world’s billionaires live in the US.

I started with a Christian quotation and so it may be appropriate to ask how generous those fortunate billionaires are towards the people of their own country? I won’t go there. A nations prosperity should not depend on the philanthropic endeavours.

This year a lot has changed. Established ways of working are getting all shook-up. Ambition, suspicion and rivalry are all taking centre stage. An ambition to be unquestionably greater than all others. A suspicion that most others are taking advantage. A fight over valuable and often limited resources.

Again, human history is littered with times when such forces took over. Interestingly, Christianity gained a footing at a time when the Roman empire was plundering anything it could get its hands on. However, I’m not advocating a moral code to moderate the instinct to be imperial.

All to often those moral codes are just moulded and shaped to fit the prevailing circumstances.

No, my appeal is to mutual advantage. The simple idea that 2+2=4 is not the be all and end all of reality. In human affairs we can with effort make 2+2 equal more. It’s that saying that the whole is greater than the sum of the parts. It’s why people work together for common advantage.

Yesterday, I don’t suppose for a moment that ancient monument that I drove past would be there if it were not for the above benefits of having common goals and a willingness to cooperate. Stonehenge.

Trade barriers are foolish. Walls prevent the spreading of prosperity.

Safety Analysis

In discussions about safety one model is often called up. Its simplicity has given it longevity. It also nicely relates to common human experience. The model is not one of those abstract ideas that take a while to understand. If you have been on a safety training course, a lecturer will give it couple of minutes and then use it to draw conclusions as to why we collect and value safety data.

On illustration, and it’s a good one for sticking in the memory, is a picture of a big iceberg. Most of an iceberg is underwater. One the surface we only see a fraction of what is there. This is the Heinrich pyramid. Or Heinrich’s Law[1] but it’s not really a law in the sense of a complete mathematical law.

The logic goes like this. In discissions about industrial major accidents, there are generally a lot more minor accidents that precede the major ones. Although this was drawn up in the 1930s the model has been used ever since. And we extend its useful applicability to transport operations as much as workplace accidents.

Intuitively the model seems to fit everyday events. Just imagine an electrical cable carelessly extended over the floor of a hanger. It’s a trip hazard. Most of the time the trips that occur will be minor, annoying events, but every so often someone will trip and incur a major injury.

What we can argue about is the number of precursor events that may occur and their severity. It wouldn’t be a simple universal ratio, either. Heinrich said there were generally about 30 accidents that cause minor injuries but 300 accidents with no injuries. A ten to one ratio.

Forget the numbers. The general idea is that of the iceberg illustration. Underlying that example of the pyramid is the notion that there are a lot more low severity events that occur before the big event happens. Also, that those low severity events may not be seen or counted.

It’s by attempting to see and count those lesser events that we may have the opportunity to learn. By learning it then becomes possible to put measures in place to avoid the occurrence of the most destructive events.

In British aviation I will reference the 1972 Staines air accident[2]. A Brussels-bound aircraft took off from London Heathrow. It crashed moments later killing those onboard. One of the findings from this fatal aircraft accident was that opportunities to learn from previous lesser events were not taken. Events not seen or counted.

Thus, Mandatory Occurrence Reporting[3] was born. Collecting data on lesser events became a way of, at least having a chance of, anticipating what could happen next. Looking at the parts of the iceberg sitting under the water.

How many fatal accidents have been prevented because of the safety analysis of data collected under MOR schemes? If only it was possible to say.

God, what next?

It’s Sunday. A day of reflection. A day when mentioning God might not be too controversial. Naturally, I might not do that in a conventional way. A train of though linking one or two events.

If I go back to my school days. Don’t worry it’s what happens when you click 65. Foolish reminiscences of day that are falling into the history books. Yes, when the 1970s are history. In the true sense of the word. Now, erudite historians chew over the earth-shattering events of my childhood. I didn’t know until this week that the Kennedy shooting in the US coincided with an event relevant to my growing-up. Adventures in space and time. The first broadcast of Dr Who.

Before I digress too much, what I was thinking about was a teacher. Johnny Rayworth. I’m unsure about the spelling of his surname name but you get the idea. To a class of misbehaving boys, his retort was: “God’s on my side. Clarence” Basically, don’t be silly boy you have no agency in my classroom. He called everyone Clarence. I suspect because he couldn’t remember names or there was some association that is lost in the mists of time.

He was one of several war years teachers at my school. This portly gentleman had a wooden leg. His subject – technical drawing. It seems remarkable in 2025 that boys were taught drawing 50-years ago. It did me no harm. My first job was in an engineering drawing office.

Evoking God as a way of saying this is good. That’s got a lot of mileage. Because the BBC like to do reminiscence too, I have a catchy lyric running through my head this morning. “God Gave Rock and Roll to You” gets repeated over and over. A simple song that started life in 1973 with a British rock band called “Argent”. They are long forgotten. Their legacy is an undeniable example of good works. The world is a better place for an uplifting song or two.

The internet is full of a lifetime of Groucho Marx quotes. The man was a master of the one liner. As an American comedian a lot of his lines sum-up the American experience but there’s a universality to them too.

This last week, however generous my thinking I’m inclined to say that we can all take generosity beyond its limits. Like the man says: “Be open minded, but not so open minded that your brains fall out.” As much as a few may say that the international trade tariff avalanche is a long-term attempt to do good in the US, the evidence points to a collective act of brains falling out.

There’s an abundance of Trump memes scattered about social media. The one I like the most this week is here.

The Curious Case of Lists

How on earth does a humble soul like me make any comment at a time like this? Adding to the realms of things already said seems a bit pointless. We now have echo chambers sounding in echo chambers. Instead, I’ll take a sideways look. Mention one or two of the items that struck me during the week.

Penguins are getting a lot of Press. Ever since Trump decided to slap a tariff on an island inhabited by penguins there’s been a lot of speculations as to his ultimate motives. If I take Feathers McGraw as an example, I can well understand the need to make a pre-emptive strike against such a potentially villainous bird.

Of other notable penguins, I can only surmise that Trump has never heard of Pingu[1]. Now, there’s a subversive penguin if ever I saw one. He originated in Switzerland, which is strange to say the least.

I almost forgot another memorable fictional penguin of the past. A threatening comic character that combines menace with a gentlemanly swager[1]. One of Batman’s greatest foes. A well dressed master criminal unlike other criminals one might mention.

I forgot it this year. Next year, I will pay attention to Penguin Awareness Day. 20 January might be winter to us but its summer to them. Birds that have the decency to dress up in black and white dinner jackets deserve some respect. I for one, will express my concern that the exports of our feathered friends may be taxed. Could it be that Trump is confused. Afterall the real penguins love the ice in the southern hemisphere. In fact, nowhere near Greenland.

“I’ve Got a Little List”. There’s a phrase that comes to mind. Lists, one in particular, does seem to have hit the News this week. I ask, why is there no modern-day equivalent of Gilbert and Sullivan? Accepted, companies do play with their songs and make words to fit the situation of the day[2]. There’s a great deal of scope for new lyrics.

The fabric of social media would rupture if there were no lists. I’m often entertained by an animation that shows a compilation of data as it ripples through the years. Something with colourful bar graphs that go up and down as the rank and order changes. A musical accompaniment that has no relation to what’s being presented. Lists are captivating. They spur a natural curiosity to look for the item of most personal interest. So, over time the economy of X or Y country goes up and then down and then up again. For sure, nothing stays the same for long. That maybe the moral of the week.

From Prescription to Performance-Based Regulation

One regulatory development that has stuck since the start of the new century is the idea that we need to transition from prescriptive requirements to performance-based requirements. It’s not too hard to understand where the motivation to change has come from but there are several strands to the path. Here’s three that come to mind.

For one, the intense dislike of overbearing governmental regulators who adopt an almost parental attitude towards industry. It’s true that safety regulatory bodies have a duty to serve the public interest. The difficulty arises in interpreting that brief. Not as police officers sometimes did, imagining everyone as a potential miscreant.

My experience as a regulator started at a time when traditional institutional approach was quite common. There was a respectful distance between the airworthiness surveyor or operations inspector and the aviation industry that they oversaw. I think, even the term “surveyor” was one inherited from the insurance industry at the birth of flying.

A wave of liberalisation swept into the 1980s. It was an anathema to those who started their careers as men from the Ministry. The idea that regulators should be in a partnership with industry to meet common goals was not easily accepted. Undoubtably a change was necessary and, naturally, easier for an up-and-coming generation.

The next move away from regulatory prescription came as its value declined. That is, not that there will not always be an element of prescription by matter of the written law. However, for detailed technical considerations it became less and less practical to say, this is the way it must be. The minute decision-makers were faced with the complexity of a microprocessor it become clear that it’s not effective to simply prescribe solutions.

Much of the changes that took place can be traced to the evolution of system safety assessment and the use of probabilistic methods in aviation. In mechanics, prescribing a safety guard for a chain drive is straightforward. For complex electronics saying when a flight system is safe enough requires a different approach. Regulators are now driven to set objective rather than dictate solutions.

My third point is a future looking one. Whatever the history and heritage of aeronautical innovation, it’s true that a “conservative” but rapid adoption of new technology continues to be a source of success. Great safety success as well as commercial success.

Hidden amongst the successes are products, and ways of working that don’t meet the grade. The joke goes something like this: “How can I make a fortune in aviation?” Answer: “Just start with a big one.” Implicit in this observation is a wiliness to innovate at risk. That means, amongst many things, having confidence, adaptability and not be so constrained as to be assured failure. An objective or performance-based approach to safety regulation opens opportunity to innovate more freely whilst still protecting the public interest in safety.

There’s no fixed destination for regulatory development.

Key Milestones in Safety Management

One chunk of a recalling of the path civil aviation has taken in the last 40-years is called: Safety Management Systems (SMS). It’s a method or set of methods that didn’t arrive fully formed. It can easy be assumed that a guru with a long white beard stormed out of his quiet hermitage to declare a eureka moment. No such thing happened.

Through every part of my engineering design career the importance of reliability and quality systems was evident. Codified, procedural and often tedious. Some say the quality movement had its origins in the world of the 1960s moonshot and the advent of nuclear weapons. I don’t think there’s a single spring from which the thinking flows.

That said, there are notable minds that shaped the development of standardised quality systems. Acknowledging that the Deming Cycle[1] is core component doesn’t take too much of a leap. It’s a simple idea for capturing the idea of continuous improvement. Aerospace design and production organisations adopted this method readily.

Those first steps were all about the Q word, Quality. How to deliver a product that reliably worked to specification. At the time the S word, Safety wasn’t spoken of in the same way. There had been an underlying presumption that quality success led to safety success. However, this was not entirely true. An aerospace product can leave a factory 100% compliant with a pile of requirements, specifications and tests only to subsequently reveal failing and weaknesses in operational service.

In the saddest of cases those failing and weaknesses were discovered because of formal accident or incident investigation. In civil aviation these are conducted independently. Worldwide accident investigators and aircraft operators often detected a lack of learning from past events. This situation stimulated activities aimed at accident prevention.

In 1984, the International Civil Aviation Organization (ICAO) published the first edition of its Accident Prevention Manual. This document introduced concepts and methods aimed at accident prevention. It was a pick and mix of initiatives and processes gleamed from the best-known practices of the time.

One of the jobs I had on joining the UK Civil Aviation Authority (CAA) Safety Regulation Group (SRG) was to work with the ICAO secretariate on an update to the Accident Prevention Manual (Doc 9422). The UK CAA has long been an advocate and early adopter of occurrence reporting and flight monitoring. Both were seen as key means to prevent aviation accidents.

It was envisaged that a second edition of the manual would be available in 2001. That didn’t happen. Instead, ICAO decided to harmonise information available on safety and put that into one manual. At that point safety information was scattered around the various ICAO Annexes. Thus, the content of the Accident Prevention Manual was consolidated into the Safety Management Manual (SMM) (Doc 9859). This new document was first published in 2006.

There’s much more to say since the above is merely a quick snapshot.

1985 to 2025 Trends

On reading J. C. Chaplin’s paper on the first 100-years of aviation safety regulation in the UK[1], it struck me that the journey from the 1910s to the 2010s was one of constant change. That change has not slowed down. In fact, the last 40-years of my aviation career have seen dramatic technological changes that have demanded ever new regulatory methods and practices.

Overwhelmingly aviation history writings obsess about the early days of flying or the start of the jet age. It’s as if those periods were so dominated by great pioneers that nothing worthy has happened since. I exaggerate for effect, but I think you get the meaning of my comment.

So, what of the race from the 1985 to the 2025? I think that is useful period to look at. One of the reasons is that those years are mark the transition from an analogue era to a digital one.

The early 1980s saw experimentation with the potential for digital technologies, most particularly fly-by-wire systems. Quickly the military understood the increase in aircraft performance that could be gained by use of such technologies. Groundbreaking was Concorde in that it demonstrated that critical electronic control systems could safely go into everyday operation. That project drove the development of new regulatory methods and practices.

A turning point occurred in the mid-1980s. That silicon revolution that impacted so much of life was dramatically put to use in civil aviation. Computing power had so miniaturised and become affordable so that past theoretical possibilities could now be practically realised.

The Airbus A320 aircraft first flew in 1987. It was a shaky start. Not everyone was convinced that safety critical systems were indeed safe. The not so obvious discovery that the human factor was even more important for a computerised aircraft. Learning to adapt and adjust ways of operating didn’t happen overnight.

The lesson is that learning lessons must be part of the process. Through applying continuous improvement, the Airbus A320 family has grown ever since.

Maybe there needs to be a short paper to cover civil aviation safety regulation from 1985 to 2025. It’s needed now. It’s needed because the next 40-years are going to see equally dramatic changes. In the time to come the main driver will be the environment.
