Cider pigs

Out the back of the farmhouse was a scruffy orchard. It was through the east facing garden, then over an awkward cobbled together fence. The orchard was an L-shape with a soggy wet depression in the middle. The trees at the top end of the orchard had long since gone by the time of my childhood. The lower part of the orchard was populated with the most venerable but neglected cider apple trees. Never pruned with that crusty, mossy look of years of struggle against the elements.

There was no money in growing cider apples in the 1960s and besides the ones that still stood were probably originally grown for homemade home consumed cider. The orchard was a piggery.  Several well-made timber pig huts stood in the field. Except for one. In a corner there was strange construction made of used railway sleepers, arranged vertically, and covered with a round tin roof. It was the only hut that was not moveable. A rough concrete floor kept the railway sleepers in place.

Now, that was a good set-up. There’s a thing that most pigs like and it’s ripe cider apples. Trouble is that they don’t know when to stop. So, when they fell, we had to find something to do with them by the bucket load. For us boys, that wasn’t a problem. Cider apple[1] wars were a feature of the autumn.

If I’d taken a shine to farming in those early years, it would have been keeping pigs. That orchard was always as carved up as a fresh battle ground. Nothing more satisfying to a happy pig than rooting through the dirt. In good weather making our way across the ground was easy. In bad weather getting stuck in the sticky clay mud was guaranteed. The thick mud was ideal in the summer. Wallows would form so the pigs could do what they do best when it gets hot.

All that said, I can’t imagine domesticated pigs in any other setting than outdoors. As I drive around, it makes me pleased to see so many examples of outdoor reared animals. Pigs are inquisitive and intelligent animals that deserve the freedom to roam around in an open space.

At one time or another, I kept a British Saddleback[2], a Landrace[3], and a Large White[4] pig.  The Large White pigs could be a handful if the pig took a disliking to you. Saddlebacks were the best when it came to temperament. Agreeable, content, and excellent mothers.

My brothers and I were being tutored in animal husbandry from a young age. The principle aim was not to pamper a pet but to look after the pigs with the aim of having as big a litter of piglets as possible. That’s where profit lay. We kept records of the cost of the pig food, bedding needs and everything that went into our mini farming enterprises.

Encouraged by my parents, my brother and I were often in competition.  I remember once sitting up late into the evening with a sow and being so proud of having helped 14 piglets into the world alive. This could be a hazardous business in a confined space of a small pig hut. The job was making sure the piglets found their way to their mother’s teat and didn’t get squashed on the way. If they let out a loud squeal the sow could move and could unwittingly squash one of the litter.

In my mind, Somerset cider is tied with pigs. The two go hand in hand.

Working hard for the money

What goes wrong with research spending? It’s a good question to ask. In some ways research spending is like advertising spending. “Half the money I spend on advertising is wasted; the trouble is I don’t know which half.[1]” Globally billions are spent on advertising so you might say – it must be working. In fact, far more is spent on advertising than is ever available for research in the aviation and aerospace world.

Research spending is a precious asset because of its bounds. Even so, a great deal of research spending is lost on activities that deliver no or little benefit. It’s true Governments, institutions and industry don’t often put-up funds for vague and imprecise aspirations or outlandish predictions but nevertheless money goes down a sink hole on far too many occasions.

A reluctance to take tough decisions or at the other extreme of the spectrum a relish in disruption plagues research funding decision making. Bad projects can live long lives and good projects get shut down before their time. My observations are that these are some of the cases that crop-up all too often across the world.

Continuing to service infrastructure that cost a great deal to set-up. It’s the classic problem of having spent large sums of money on something and thereby the desperation to see a benefit encourages more spending. Nobody likes to admit defeat or that their original predictions were way off the mark.

Circles of virtue are difficult to address. For example, everyone wants to see a more efficient and sustainable use of valuable airspace therefore critics of spending towards that objective are not heard. That is even if substantial spending is misdirected or hopelessly optimistic.

Glamourous and sexy subjects, often in the public limelight, get a leg-up when it come to the evaluation of potential research projects. Politicians love press photographs that associate them with something that looks like a solution in the public mind. Academics are no different in that respect.

Behold unto the gurus! There’s conferences and symposiums where ideas are hammered home by persuasive speakers and charismatic thinkers. Amongst these forums there are innovative ideas but also those that get more consideration than they warrant.

Narrow focused recommendations can distort funding decision making. With the best of intent an investigation or study group might highlight a deficiency that needs work, but it sits in a distinct niche of interest. It can be a push in direction the opposite of a Pareto analysis[2].

Highlighting these points is easier than fixing the underlying problems. It’s a good start to be aware of them before pen and ink meets, and a contract is signed.

Light touch folly

Light touch regulation. Now, there’s a senseless folly. It’s a green light to bad actors wherever they operate. It’s like building a medieval castle’s walls half as thick as planned to save money in the belief that enemies are too stupid to work it out. Saying that the public good far less important than the speed of developments is unwise to say the least.

The INTERNET arrived in the UK in the late 1980s. Now, it seems strange to recount. Clunky Personal Commuters (PCs) and basic e-mail were the hight of sophistication as we moved from an office of typewriters and Tipp-Ex to the simple word processor[1]. Generations will marvel at the primitive nature of our former working lives. Getting scissors and cutting out paper text and pasting it into a better place in a draft document. Tippexing out errors and scribbling notes in the spaces between sentences. Yet, that’s what we did when first certifying many of the commercial airliners in regular use across the globe (Boeing 777. Airbus A320). Desktop computers took centre stage early in the 1990s, but administrations were amid a transition. Clickable icons hit screens in 1990. Gradually and progressively new ways of working evolved.

Microsoft Windows 95 and the INTERNET were heralded as the dawn of a new age. Not much thought was given to PCs being used for criminal or malicious purposes. No more thought than the use of a typewriter to commit crime. That doesn’t mean such considerations were ignored it just means that they were deemed a lower-level importance.

In 2023, everyday there’s a new warning about scammers. Even fake warnings about scammers coming from scammers with the aim of scamming. Identifying whose real and whose a fake is becoming ever more difficult. Being asked to update subscriptions that were never opened in the first places is a good indicator that there’s some dirty work afoot. Notices that accounts are about to be blocked referring to accounts that don’t exist is another.

In 30-years the INTERNET has taken on the good and bad of the greater world. It hasn’t become a safer place. In fact, it’s become a bit like the Wild West[2].

Our digital space continues to evolve but has nowhere near reached its potential. It’s like those great western plains where waggons headed out looking for rich new lands. In any towns on the way the shop fronts are gleaming and inviting but if you look around the back there’s a desperate attempt to keep bad actors at bay.

Only a fraction of the suspicious, emails, texts, and messages get reported. People unconsciously pile up a digital legacy and rarely clean out the trash that accumulates. A rich messiness of personal information can lie hidden to the eyes but just bellow the digital surface.

When politicians and technocrats talk of “light touch regulation” it’s as if none of this matters. In the race to be first in technology, public protection is given a light touch. This can’t be a good way to go.

Pointless Brexit

Democracy’s malleable frame. I don’t recall the people of the UK being given a referendum on joining a trade block in the Pacific. Nice thou it is to have good relations with trading nations across the globe it seems strange that the other side of the world is seen as good and next door is seen as bad. It’s like a person looking through a telescope through the wrong end.

Back on 23rd June 2016, voters in the UK were asked if Britain should leave the EU. No one really knew what “leave” meant as all sorts of, what now turns out to be blatant lies were told to the public. The words “customs union” were not spoken in 2016. If they were it was in a tone of – don’t worry about all that, we hold all the cards, nothing will change.

Today, UK sectors from fishing to aviation, farming to science report being bogged down in ever more red tape, struggling to recruit staff, and racking up losses. Sure, Brexit is not the only trouble in the world, but it was avoidable unlike the pandemic and Putin’s war.

We (UK) became a country that imposed sanctions on itself. A unique situation in Europe. If some people are surprised, we have significant problems the really ought to examine what happened in 2016. It’s a textbook example of how not to do thing. The events will probably be taught in schools and universities for generations to come as a case of national self-harm.

Democracy is invaluable but when a government dilutes a massive question into a simple YES or NO, they dilute democracy too. It’s the territory that demigods thrive in. Mainly because this approach encourages the polarisation that then drives ever more outlandish claims about opponents. The truth gets buried under a hail of campaign propaganda, prejudice, and misinformation.

What Brexit has stimulated. A growth sector, I might say. Is the blame game. Now, when things go wrong, UK politicians can always blame those across the other side of the Channel. Standing on the cliffs in Dover its easy to survey the mess and point a finger out to sea.

If some people’s motivation for voting for Brexit was to control borders and stopping immigration the failures are so obvious that they hardly need to be pointed out. Yet, politicians persist with they myth that a solution is just around the corner if only UK laws were made ever more draconian. A heavier hand, criminalisation and the blame game are not solutions. These acts will merely continue the round of calamities and failures.

Brexit has unlocked a grand scale of idiocy. The solution is to consign this dogma to the past.

Pause

An open letter has been published[1]. Not for the first time. It asks those working on Artificial Intelligence (AI) to take a deep breath and pause their work. It’s signed by AI experts and interested parties, like Elon Musk. This is a reaction to the competitive race to launch ever more powerful AI[2]. For all technology launches, it’s taking fewer and fewer years to get to a billion users. If the subject was genetic manipulation the case for a cautious step-by-step approach would be easily understood. However, the digital world, and its impact on our society’s organisation isn’t viewed as important as genetics. Genetically Modified (GM) crops got people excited and anxious. An artificially modified social and political landscape doesn’t seem to concern people quite so much. It maybe, the basis for this ambivalence is a false view that we are more in control of one as opposed to the other. It’s more likely this ambivalence stems from a lack of knowledge. One response to the open letter[3] I saw was thus: A lot of fearmongering luddites here! People were making similar comments about the pocket calculator at one time! This is to totally misunderstand what is going on with the rapid advance of AI. I think, the impact on society of the proliferation of AI will be greater than that of the invention of the internet. It will change the way we work, rest and play. It will do it at remarkable speed. We face an unprecedented challenge. I’m not for one moment advocating a regulatory regime that is driven by societal puritans. The open letter is not proposing a ban. What’s needed is a regulatory regime that can moderate aggressive advances so that knowledge can be acquired about the impacts of AI. Yesterday, a government policy was launched in the UK. The problem with saying that there will be no new regulators and regulators will need to act within existing powers is obvious. It’s a diversion of resources away from exiting priorities to address challenging new priorities. That, in of itself is not an original regulatory dilemma. It could be said, that’s why we have sewage pouring into rivers up and down the UK. In an interview, Conservative Minister Paul Scully MP mentioned sandboxing as a means of complying with policy. This is to create a “safe space” to try out a new AI system before launching it on the world. It’s a method of testing and trials that is useful to gain an understanding of conventional complex systems. The reason this is not easily workable for AI is that it’s not possible to build enough confidence that AI will be safe, secure and perform its intended function without running it live. For useful AI systems, even the slightest change in the start-up conditions or training can produce drastically different outcomes. A live AI system can be like shifting sand. It will build up a structure to solve problems, and do it well, but the characteristics of its internal workings will vary significantly from one similar system to another. Thus, the AI system’s workings, as they are run through a sandbox exercise may be unlike the same system’s workings running live. Which leads to the question – what confidence can a regulator, with an approval authority, have in a sandbox version of an AI system? Pause. Count to ten and work out what impacts we must avoid. And how to do it.

Policy & AI

Today, the UK Government published an approach to Artificial Intelligence (AI)[1]. It’s in the form of a white paper. That’s a policy document creäte by the Government that sets out their proposals for future legislation.

This is a big step. Artificial Intelligence (AI) attracts both optimism and pessimism. Utopia and dystopia. There are a lot more people who sit in these opposing camps as there are who sit in the middle. It’s big. Unlike any technology that has been introduce to the whole populous.

On Friday last, I caught the film iRobot (2004)[2] showing early evening on Film 4. It’s difficult to believe this science fiction is nearly 20-years old and the short story of Isaac Asimov’s, on which it’s based is from the 1950s. AI is a fertile space for the imagination to range over a vast space.

Fictional speculation about AI has veered towards the dystopian end of the scale. Although that’s not the whole story by far. One example of good AI is the sentient android in the Star Trek universe. The android “Data” based on the USS Enterprise, strives to help humanity and be more like us. His attempt to understand human emotions are often significant plot points. He’s a useful counterpoint to evil alien intelligent machines that predictably aim to destroy us all.

Where fiction helps is to give an airing to lots of potential scenarios for the future. That’s not trivial. Policy on this rapidly advancing subject should not be narrowly based or dogmatic.

Where there isn’t a great debate is the high-level objectives that society should endeavour to achieve. We want technology to do no harm. We want technology to be trustworthy. We want technology to be understandable.

Yet, we know from experience, that meeting these objectives is much harder than asserting them. Politicians love to assert. In the practical world, it’s public regulators who will have to wrestle with the ambitions of industry, unforeseen outcomes, and negative public reactions.

Using the words “world leading” successively is no substitute for resourcing regulators to beef-up their capabilities when faced with rapid change. Vague and superficial speeches are fine in context. Afterall, there’s a job to be done maintaining public confidence in this revolutionary technology.

What’s evident is that we should not delude ourselves. This technical transformation is unlike any we have so far encountered. It’s radical nature and speed mean that even when Government and industry work together they are still going to be behind the curve.

As a fictional speculation an intelligent android who serves as a senior officer aboard a star ship is old school. Now, I wonder what we would make of an intelligent android standing for election and becoming a Member of Parliament?


[1] The UK’s AI Regulation white paper will be published on Wednesday, 29 March 2023. Organisations and individuals involved in the AI sector will be encouraged to provide feedback on the white paper through a consultation which launches today and will run until Tuesday, 21 June 2023.

Good enough

It’s not a universal rule. What is? There are a million and one ways that both good and bad things can happen in life. A million is way under any genuine calculation. Slight changes in decisions that are made can head us off in a completely different direction. So much fiction is based on this reality.

Yes, I have watched “Everything Everywhere All at Once[1]”. I’m in two minds about my reaction. There’s no doubt that it has an original take on the theory of multiple universes and how they might interact. It surprised me in just how much comedy formed the core of the film. There are moments when the pace of the story left me wondering where on earth is this going? Overall, it is an enjoyable movie and its great to see such originality and imagination.

This strange notion of multiple universes, numbered beyond count, has an appeal but it’s more than a headful. What I mean is that trying to imagine what it looks like, if such a thing is possible, is almost hopeless. What I liked about the movie is that small difference are more probable and large difference are far less probable. So, to get to the worlds that are radically different from where you are it’s necessary to do something extremely improbable.

Anyway, that’s not what I’m writing about this morning. I’ve just been reading a bit about Sir Robert Alexander Watson Watt. The man credited with giving us radar technology.

Perfect is the enemy of good is a dictum that’s has several attributions. It keeps coming up. Some people celebrate those who strive for perfection. However, in human affairs, perfection, is an extremely improbable outcome in most situations. There’s a lot of talent and perspiration needed to jump from average to perfect in any walk of life.

What the dictum above shorthand’s is that throwing massive amounts of effort at a problem can prevent a good outcome. Striving for perfection, faced with our human condition, can be a negative.

That fits well with me. My experience of research, design and development suggested the value of incremental improvement and not waiting for perfect answers to arise from ever more work. It’s the problem with research funding. Every paper calls for more research to be done.

In aviation safety work the Pareto principle is invaluable. It can be explained by a ghastly Americanisms. Namely, let’s address the “low hanging fruit” first. In other words, let’s make the easiest improvements, that produce the biggest differences, first.

I’m right on-board with Robert Watson-Watt and his “cult of the imperfect”. He’s quoted saying: “Give them the third best to go on with; the second best comes too late, the best never comes”. It’s to say do enough of what works now without agonising over all the other possible better ways. Don’t procrastinate (too much).

Comms

The long history of data communications between air and ground has had numerous stops and starts. It’s not new to use digital communications while flying around the globe. That said, it has not been cheap, and traditional systems have evolved only slowly. If we think Controller Pilot Data Link Communications (CPDLC)[1] is quite whizzy. It’s not. It belongs to a Windows 95 generation. Clunky messages and limited applications.

The sluggishness of adoption of digital communications in commercial aviation has been for several reasons. For one, standardised, certified, and maintainable systems and equipment have been expensive. It’s not just the purchase and installation but the connection charges that mount-up.

Unsurprisingly, aircraft operators have moved cautiously unless they can identify an income stream to be developed from airborne communication. That’s one reason why the passengers accessing the internet from their seats can have better connections than the two-crew in the cockpit.

Larger nations’ military flyers don’t have a problem spending money on airborne networking. For them it’s an integral part of being able to operate effectively. In the civil world, each part of the aviation system must make an economic contribution or be essential to safety to make the cut.

The regulatory material applicable to Airborne Communications, Navigation and Surveillance (CS-ACNS)[2] can be found in publications coming from the aviation authorities. This material has the purpose of ensuring a high level of safety and aircraft interoperability. Much of this generally applicable material has evolved slowly over the last 30-years.

Now, it’s good to ask – is this collection of legacy aviation system going to be changed by the new technologies that are rapidly coming on-stream this year? Or are the current mandatory equipage requirements likely to stay the same but be greatly enhanced by cheaper, faster, and lower latency digital connections?

This year, Starlink[3] is offering high-speed, in-flight internet connections with global connectivity. This company is not the only one developing Low Earth Orbit (LEO)[4] satellite communications. There are technical questions to be asked in respect of safety, performance, and interoperability but it’s a good bet that these new services will very capable and what’s more, not so expensive[5].

It’s time for airborne communications to step into the internet age.

NOTE: The author was a part of the EUROCAE/RTCA Special Committee 169 that created Minimum Operational Performance Standards for ATC Two-Way Data Link Communications back in the 1990s.

Just H

What is the future of Hydrogen in Aviation? Good question. Every futurologist has a place for Hydrogen (H) in their predictions. However, the range of optimistic projections is almost matched by the number of pessimistic ones.

There’s no doubt that aircraft propulsion generated using H as a fuel can be done. There’s a variety of way of doing it but, the fact is, that it can be done. What’s less clear is a whole mass of factors related to economics, safety and security and desirability of having a hydrogen-based society.

H can be a clean form of energy[1], as in its purest form the process of combustion produces only water. We need to note that combustion processes are rarely completely pure.

It’s an abundant element but it prefers to be in company of other elements. Afterall, the planet is awash with H2O. When H is on its own it has no colour, odour, or taste. In low concentrations, we humans could be oblivious to it even though there’s a lot of it in the compounds that make us up.

Number one on the periodic table, it’s a tiny lightweight element that can find all sorts of ways of migrating from A to B. Ironically, that makes it an expensive element to move around in commercially useable quantities. H is often produced far away from where it’s used. For users like aviation, this makes the subject of distribution a fundamental one.

Part of the challenge of moving H around is finding ways of increasing its energy density. So, making it liquid or pumping it as a high-pressure gas are the most economic ways of using it. If this is to be done with a high level of safety and security, then this is not going to come cheap.

There are a lot of pictures of what happens when this goes wrong.  Looking back at the airships of the past there are numerous catastrophic events to reference. More relevantly, there’s the space industry to look at for spectacular failures[2]. A flammable hydrogen–air mixture doesn’t take much to set it off[3]. The upside is that H doesn’t hang around. Compared to other fuels H is likely to disperse quickly. It will not pool on the ground like Kerosene does.

In aviation super strict control procedure and maintenance requirements will certainly be needed. Every joint and connectors will need scrupulous attention. Every physical space where gas can accumulate will need a detection system and/or a fail proof vent.

This is a big new challenge to aircraft airworthiness. The trick is to learn from other industries.

NOTE: The picture. At 13:45 on 1 December 1783, Professor Jacques Charles and the Robert brothers launched a manned balloon in Paris. First manned hydrogen balloon flight was 240 years ago.

Artificial intelligence (AI) transition

There’s much that has been written on this subject. In fact, for a non-specialist observer it’s not so easy to get to grips with the different predictions and views that are buzzing around.

There’s absolutely no doubt that Artificial intelligence (AI) will change every corner of society. Maybe a few living off-grid in remote areas will remain untouched but every other human on the planet will be impacted by AI. Where there’s digital data there will be AI. Some will say this brings the benefits of AI into our everyday and others herald a pending nightmare where we lose control.

Neither maybe totally on the money but what’s clear is that this is no ordinary technological transition. Up until now, the software we use has been a tool. Built for a purpose and shaped by those who programmed its code. AI is not like that at all. It’s a step beyond just a tool.

Imagine wheeling a hammer that changed shape to suite a job, but the user had no control over the shape it took. How will we take to something so useful but beyond our immediate control?

In civil aviation, AI opens the possibility of autonomous flight, preventive maintenance, and optimal air traffic management. It may work with human operators or replace them in its more advanced future implementations. Even the thought of this causes some professional people to recoil.

I’ve just finished reading the book[1] of a former Google chief officer, Mo Gawdat and he starts off being pessimistic about the dangers of widespread general AI. As he moves through his arguments, the book points to us as the problem and not the machines. It’s what we teach AI that matters rather than the threat being intrinsic to the machine.

To me, that makes perfect sense. The notion of GIGO[2] or “Garbage In, Garbage Out” has been around as long as the computer. It does, however, put a big responsibility on those who provide the training data for AI or how that data is acquired.

Today’s social media gives us a glimpse of what happens when algorithms slavishly give us what we want. Anarchic public training from millions of hand-held devices can produce some undesirable and unpleasant outcomes.

It maybe that we need to move from a traditional software centric view of how these systems work to a more data centric view. If AI starts with poor training data, the outcome will be assuredly poor.

Gawdat dismisses the idea that general AI can be explainable. Whatever graphics or equations that may be contrived they are not going to give a useful representation of what goes on inside the machine after a period of running. An inability to explain the inner working of the AI maybe fine for non-critical applications but it’s a problem in relation to safety systems.
