Shameful

Let’s look at the current fetor objectively. Is it reasonable to say that the Government is using language that is reminiscent of political parties in Germany in the 1930s?

Politicians speaking stridently about making new laws plays well with media commentators and meets the need of being seen to be doing something, even if that something is highly flawed.

To marshal support for a much-criticised proposal, the language being used by Conservative politicians is harsh. Speaking in the House of Commons, a Minister said “there are 100 million people” who would qualify for asylum in the UK. This is reminiscent of the right-wing rhetoric used in 2016 by the referendum Leave campaign to say that 10s of million of Turkish people would come to the UK is we stayed in the European Union (EU).

Shamefully, scare stories about migration are the bread and butter of right-wing politicians much as they were in early 1930s in Germany. It’s clear, that the much-discussed Tweet by a well know football commentator[1], this last week has touched a political nerve. The truth often does touch a nerve.

There’s more than double trouble with Conservative politicians forcing the UK’s “independent” national broadcaster to sanction a well know football commentator for a private remark.

Godwin’s law[2] is known to politicians but maybe not more widely known. Basically, starting an argument by mentioning a comparison to Nazis is not a good a way to win a case. It’s that making an extreme comparison can undermine the credibility of a fair case against something bad.

Now, a national broadcaster with an obligation to aim for political impartiality, with respect to news and current affairs, is inconsistency jumping on the head of one of its popular faces. 

It’s sad that scrutiny of a proposal for a bad law is being overshadowed by an entirely unnecessary media spat. An unnecessary spat that is undermining free speech in the UK[3]. I do not think that Conservative politicians engineered this situation, but they unjustly are benefiting from it. The controversy is corralling right-wing support for a government bill that is full of holes.

I don’t know how we got to this ridiculous state but it’s part of a trend that has been evident since 2016. The reason an evil political party succeeded in Germany in the early 1930s is that they masked their true intent, and countless people discounted their prospects of electoral success. There’s an important lesson in history that we should never ignore.

The language politicians use does matter. It matters a lot.

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.

Small Boats

Are there really hundred million people coming to Britain? Or is this a desperate scare tactic adopted by a Conservative Minister who has run out of workable ideas? It’s certainly the sort of tabloid headline that a lot of conservative supporters like to read. As we saw in the US, with former President Trump’s rhetoric on building a wall these themes stir-up negative emotions and prejudice. It’s a way of dividing people.

Xenophobia is defined as a fear and hatred of strangers or foreigners or of anything that is strange or foreign. With nearly 8 billion people on Earth[1] the potential for this destructive fear to be exploited has never been greater. Here, the Conservative Party is increasingly dominated by xenophobia and demagoguery, whatever a change of leadership may be trying to cover-up.

Will Parliamentary debate save us from the worst instincts highlighted in the Government’s latest proposals on small boat crossings? That’s a big question when the ruling political party has such a large parliamentary majority. Debate is likly to be heated and lacking objectivity.

Pushing the boundaries of international law can cause reputational damage, even if these rum proposals are defeated. However, what concerns most commentators is the high likelihood that the proposed measure will not work. They are merely a more extreme version of past failed policies.

One of the poorest political arguments is to criticise an opponent for reasoned opposition. It goes like this: here’s my policy and by opposing, it without providing your policy, you automatically make my policy a good one. It’s like planning to build a dangerously rickety bridge, likely to fail, and pointing to those who criticise the project as a reason why it’s a good to project.

When spelt out, like this it’s clear how curiously subversive this shoddy bombast can be. However, one of the basic party-political instincts, to seek headlines and publicity, has overridden common sense in this case. In the Government’s case, legislating regardless of the consequences, is an act of political desperation. Sadly, that’s where we are in this pre-election period.

NOTE: In June 2022, the UK had a prison population of roughly 89,520 people. The detention facilities needed to enable the Government’s small boats policy would need to be in the region of 40,000 people. Yet, there’s no published plan for a significant expansion of detention facilities.

Big Red Barn

Farmers lung is not a myth. Or at least the causes are real. Being under a haybarn roof on a super-hot summer day with dust and chaff saturating the air is not to be recommended. The red painted galvanised tin roof of the barn created an oven to work in.

Haymaking was a big event in my family’s year. My pocket money was earnt at haymaking time. My brothers and I did a lot for 25p an hour.

It was never entirely the same from year to year. That is, even if the work of cutting grass, drying it, baling it, stacking it, and hauling it back to the barn was the same. Weather made the biggest difference. Damp heavy bales or light dry bales are a world apart.

Each field presented a different test of our strength and endurance. They all had names. “Big Ground” was flat, wide, and open but wet at one end. “Pump Ground” sloped towards the small brook and had its own ruts and wet patches. “Goulds Farm Moor” was a far-off place, or it seemed to me, that was bounded by the River Cale. “Little Ground” was the easiest and its name says why.

Back to the big red barn. We refined stacking hay bales as if it was an artform. There were good practical reasons for taking care where hay bales were placed. They were building bricks. Like Lego. Stacking them alternately gave some stability. We learnt by making mistakes. If we didn’t stack them differently from layer to layer the whole construction would move alarmingly or present crevasses which were less than safe.

In the big red barn, at least the steel uprights gave some square corners and support. In a field, a hayrick had to be built with a sound foundation and skill otherwise it would not survive the winter.

Most of the summertime, it was too hot and sweaty to wear gloves. That wasn’t so bad when baler twine was made of sisal[1]. As polythene baler twine came along it could be brutal on the hands.

As a 15-year-old, my ability to throw hay bales across a barn is not something I could match now. That is picking them off a much abused Lister bale elevator and then throwing them to whoever was staking, Dad or one of my brothers. We’d swap jobs from time to time. Staking was often the hardest job. Keeping up with the pace was tough.

As an aside the bale elevator[2] itself was a story. Every year, Dad would grease and oil it to make sure the moving parts worked. Inevitably the winter took its toll on the mechanics and a fix had to be improvised. I use the word “improvised” but what I really mean is botched. Baler twine, coach bolts and nails have many uses.

Powering the whole contraption was a much-abused Briggs and Stratton petrol engine[3]. It had a cord pull start. It was one where we often pulled endlessly in hope rather than and chance of getting it to start. When it did start, if the drive chain didn’t come off, it would warble away contently.

It’s droning sound moved up and down the scales as more or less bales were place on the elevator. If, usually my Mum, would put more than 4 bales on the conveyer it would all but stop. Slowly puffing away and straining to get the load to move. Most disturbing was the habit the engine had of leaking petrol. How we never came to burn down a hay barn or stack I will never know.

Looking back in time, the whole show was a health and safety nightmare. In 1975, that was not the overriding thought that went through anyone’s head. We live to tell the tale.

App folly

Isabel Oakeshott is interviewed. We are no wiser. The ins and outs of the story of Conservative Government Ministers during the COVID pandemic lockdowns is a story that will be written a thousand times. Hectares of the social media landscape will repeat every embarrassing blunder and poorly thought-out assertion. These ins and outs need to be dissected but it’s not work for those tying to improve their mental health.

People who have had some exposure to British politics often love “Yes Minister”, the BBC series that overflowed with wit, twists and turns. It lifted the lid on the stumbling workings of Whitehall and the political class. At the time the series was made there were no mobile phones in every pocket and paper was still king. Civil servants carried bundles of files down endless corridors. This wood panelled and stuffy environment was a commonplace image.

Opening a file really meant getting a folder and putting numerous memos and reports in it. Staking it high with the record of decision-making for future generations of historians to dissect.

In the 1970s, the speed of communication was mitigated by the medium. When it came to paper trails, that was a relatively human speed. Typed up memos were rarely dashed off without a thought. Documents were released with an official stamp and multiple signatories.

Fast forward to the 2020s. Office desks appear totally different from the past, that is if one exists at all. Mobiles have concentrated super-fast digital communication tools into the palm of a hand.

That said, official and unofficial communication channels continue to play their part in the corridors of power. What is shocking, in the current news stories is just how much the unofficial communication channels seem to dominate.

Afterall, we are not taking about a release of official Government emails. It’s worth asking; why are Government Ministers using WhatsApp[1] so much? It’s a widely available commercial messaging application owned by the US company Meta.

Is the machinery of political governance getting so lax in the UK that we are behold unto a messaging mobile App over which we have no control what-so-ever? 

Globally, WhatsApp may have over 2 billion users but that’s no guarantee of its integrity. The system does get hacked. Ministers using unofficial communication channels as if they were totally within their control are foolish, unethical, and naïve, to say the least.

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.

To provoke

Social media provocateurs are on the rise. Say something that’s a bit on the edge and wait for the avalanche of responses. It’s a way of getting traffic to a site. The scientific and technical sphere has these digital provocateurs less than the glossy magazine brigade, but the phenomena is growing.

Take a method or technique that is commonly used, challenge people to say why it’s good while branding it rubbish. It’s not a bad way to get clicks. This approach to the on-line world stimulates several typical responses.

One: Jump on-board. I agree the method is rubbish. Two: I’m a believer. You’re wrong and here’s why. Three: So, what? I’m going to argue for the sake of arguing. Four: Classical fence sitting. On the one hand you maybe right on the other hand you may be wrong.

Here’s one I saw recently about safety management[1]. You know those five-by-five risk matrices we use – they’re rubbish. They are subjective and unscientific. They give consultants the opportunity to escalate risks to make new work or they give managers the opportunity to deescalate risk to avoid doing more work. Now, that’s not a bad provocation. 

If the author starts by alleging all consultants and managers of being manipulative bad actors that sure is going to provoke a response. In safety management there are four pillars and one of them is safety culture. So, if there are manipulative bad actors applying the process there’s surely a poor safety culture which makes everything else moot.

This plays into the discomfort some people have with the inevitable subjectivity of risk classification. It’s true that safety risk classification uses quantitative and qualitative methods. However, most typically quantitative methods are used to support qualitative decisions.

There’s an in-built complication with any risk classification scheme. It’s one reason why three-by-three risk matrices are often inadequate. When boundaries are set there’s always the cases to decide for items that are marginally one side or other side of a prescribed line.

An assessment of safety risk is just that – an assessment. When we use the word “analysis” it’s the supporting work that is being referenced. Even an analysis contains estimations of the risk. This is particularly the case in calculations involving any kind of human action.

To say that this approach is not “scientific” is again a provocation. Science is far more than measuring phenomena. Far more than crunching numbers. It includes the judgement of experts. Yes, that judgement must be open to question. Testing and challenging is a good way of giving increased the credibility of conclusions drawn from risk assessment.

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.

Every little helps

When drawing comparisons with parts of the UK, it’s responsible to say that the town I live in, Reigate[1] in Surrey is relatively affluent. However, much debt people may be carrying, the amount purchasers are prepared to pay for houses in this town is way above the national average.

Past associations between affluence and the habit of voting Conservative in local and national elections is well established. That said, for a good half of the population in Reigate there’s no love of what the Conservatives have done over the last 12 years. In fact, I would wager that a good number of former Conservative supporters are well and truly fed-up with the never-ending deception and incompetence of that political party.

Yesterday morning, just for a short while, in the chilly air a few local people gathered on a street corner to protest. Their concerns included polluted rivers, climate crisis, cost of living crisis, real incomes falling, idiotic Government rhetoric, corrupt politics, a damaging Brexit, and the suppression of the right to protest. The public response was overwhelmingly positive. Drivers tooted their horns in support, people waved and stopped to chat.

As is perfectly reasonable, there were a small number of passers-by who disagreed with the group’s banners and posters. Most often this was a shaking of the head or a traditional English gesticulation, but in addition one or two words were voiced. That’s the heart of the matter. It mystifies me how some people can be happy with the current predicament in Britain.

The most distressing words uttered were: “What’s the choice?”

There are several ways to interpret this negative shout-out. One: it could be a cry of genuine desperation.  Two: it could be a deep reticence accepting a bad situation and a loss of hope. Three: it could be a stubborn Conservative who’d be happy regardless of the situation.

This is what those who want to see change happen have got to get to grips with this year. To bring real change about there needs to be a big collection of people who openly welcome change. That does mean embracing those who are still sitting on the fence.

It means seriously building confidence that today’s troubles can be beaten. As can be seen from this small group’s posters the list of troubles is long, so this is no simple task. Hope for the future means overturning incompetent incumbents and giving a chance to competent fresh faces. It means having honest and practical solutions ready to go. It means having a vision. 

Rebuilding Britain’s liberal democracy is the vital and urgent mission.

Turnip

Root crops come in different shapes and forms. In Britain, most of our sugar comes from sugar beets[1]. It’s weaned the country off colonial sourced sugar cane of decades ago[2]. It’s a large home-grown industry that goes on under the radar. Given recent utterances, Government Ministers may not know that it exists.

There are deep cultural themes that are associated with root crops in Britan. Some of this imagery comes from a long history of growing root crops. Some of this comes from the British war time experience of ploughing up every available space for food production. In a time of food rationing the humble turnip played a key role. The turnip, Brassica rapa L., is one of the world’s oldest cultivated vegetables. Afterall they don’t require a lot of attention and can endure hostile weather quite well.

It’s a common myth that we (the British) all eat seasonally. It was mostly the poorer people in a community who had little choice.

My own recollection is of my father unsuccessfully growing a small field of turnips. They will grow in heavy Somerset clay soil but the mess of cultivating them on land that floods is beyond a joke. Machinery gets bogged down and the harvest is more dirt than turnips. I remember that the crop made good animal feed and little else. The field was quickly retuned to a new lay of grass.

This week, Conservative Secretary of State for the Environment, Food and Rural Affairs Therese Coffey told the UK Parliament: “lot of people would be eating turnips[3]…”. This was a government statement addressing empty British supermarket shelves.

Now, I’m not about to have a downer on the poor turnip. They are a bit of an acquire taste but have meritorious qualities and are inexpensive. It’s more the silliness of the Minister’s utterance in the House of Commons that is surprising. It’s a naive exposition that casts the vital subject of food security as a comic game. The Minister doesn’t seem to have a command of her brief.

We all know that crop production can be sensitive to weather conditions throughout the growing season and at harvest. Farmers know that and live that fact. Supermarkets know that and live that fact. Both food production and distribution adapt, accordingly.

The British problem is that the cost of production has rocketed. Brexit and high energy costs have hammered farmers. Former specialisms in agriculture, like tomato production under glass, are not sufficiently supported to remain viable in current condition. In fact, tomato production is not alone in this respect.

What’s clear is that the UK’s Minister needs to get a grip. She needs to understand the nature of British agriculture and stop making foolish excuses.
