NATS

A “technical issue” has caused UK National Air Traffic Services, NATS to impose air traffic flow restrictions[1]. They did not close UK airspace. This was not a repeat of the volcanic ash events of early 2010. Going from a fully automated system to a fully manual system had the dramatic impact that might be expected. The consequences, on one of the busiest weekends in the holiday calendar were extremely significant. Huge numbers of people have had their travel disrupted. Restricting the air traffic system ensured that aviation safety was maintained. The costs came to the UK’s air traffic handling capacity and that meant delays and cancelled flights.

Although the failures that caused the air traffic restriction were quickly resolved the time to recover from this incident meant it had a long tail. Lots of spoilt holidays and messed up travel plans.

It is normal for an Air Traffic Service (ATS) provider to undertake a common cause failure analysis. This is to identify multiple failures that may result from one event. So, the early public explanations coming from NATS of the causes of this major incident are surprising. Across the globe, contingency planning is a requirement for ATS. The requirement for the development, promulgation and application of contingency plans is called up in international standards, namely ICAO Annex 11.

So, the story that a single piece of flight data brought down the traffic handling capacity of a safety related system, to such a low level, is difficult to accept. It’s evident that there is redundancy in the systems of NATS, but it seems to be woefully inadequate when faced with reality. ATS comprise of people, procedures, and systems. Each has a role to play. Safety of operations comes first in priority and then air traffic handling capacity. What we know about even highly trained people and data entry is that human error is an everyday issue. System design and implementation needs to be robust enough to accommodate this fact. So, again attributing such a highly disruptive event to one set of incorrect data inputs does not chime with good practice or basic aviation safety management. It is concerning that one action can bring down a major network in this way.

EUROCONTROL would have had been sent a “rogue” flight plan in the same way as UK NATS. Brussels does not seem to have had the problems of the UK.

It is early days in respect of any detailed technical investigation. Drawing conclusions, whatever is said in public by senior officials may not be the best thing to do.

Calls for compensation have a good basis for proceeding. The holiday flight chaos across Europe comes down to one single failure, if initial reports are correct. That can not be acceptable. The incident left thousands stranded abroad with high costs to pay to get home.

Before privatisation, there was a time when the UK Civil Aviation Authority (CAA), ran the nation’s air traffic services[2]. It had a poor reputation at the time. I remember a popular newspaper cartoon saying – and now for some clowns from the CAA. They were entertaining delayed passengers.

UK NATS has done much good work to manage a safe expansion in air traffic and address many changes in technology, it would be a shame if this sad incident marks a decline in overall network performance.

NOTE 3: The likelihood of one in 15 million sounds like a low number but it’s not “incredibly rare” by any definition. Certainty when there are around 6000 flights a day in the UK. A duplicate error occurring is a basic error that could be anticipated.

Even more H2

There’s a couple of Hydrogen related topics that are worth a moment. One is super conductors and the other is fire.

Heavy complex equipment like the magnets for particle accelerators use superconductors[1]. When there’s space and a need for powerful magnetics, materials with special physical properties, at extreme cold temperatures find a good use.

Talk of room-temperature superconductors is far from what it seems. Such a wonderful innovation is a million miles from any practical applications, if it exists at all. There’s no theory of high-temperature superconductivity, but there’s quite a few physicists who would like to find one[2].

Aviation researchers search for high temperature superconductors for electrical propulsion with extraordinary performance is on. The likelihood of success is low, and the timeframes are very long.

When an aircraft is flying at high altitude, the cabin altitude is maintained for the safety and comfort of passengers and crew. Air compressors, valves, sensors, and controllers make sure that cabin pressure remains at equivalent to an altitude of about 8,000 feet, and lower in some cases. So, any kind of simply flammable gasses or materials inside an aircraft cabin are a definite no no. It’s a big hazard.

In flight, the positive pressure should keep leaking gas out of the cabin. That is as long as the sources of fresh air for the cabin are keep well away from potential leaks.

That’s where Hydrogen gas can present trouble. Leaks can be common in dynamic Hydrogen systems. Storage tanks must be very strong to resist pressures and insulated to keep cold, at around –250°C. Escaping H2 gas is tiny. If that’s vented overboard then the risk of explosion or fire is significantly lowered. Knowing the exact flows of liquid or gas is a must.

However, if the gas finds its way into a pressurise cabin that basic option is limited. Not only that but detecting low concentrations of the gas in the first place is mighty difficult. Its odourless but at least Hydrogen isn’t poisonous.

The big safety issue is that the gas has a very wide flammability range (4 – 70% H2 in air mixture)[3]. Yes, H2 needs a spark to ignite. A typical aircraft cabin environment will easily provide that event. Dry air and static electricity will do it even if other sources will not.

To compound difficulties, if H2 does ignite, and not explode, then its flame may not be visible to the human eye. The flame is almost colourless. Certainly, not what most people think of as a gas flame. Gas and flame detectors could be installed in aircraft cabins and baggage compartments. Audible and visual alarms could be generated but what would be the associated crew actions?

All the above requires detailed consideration in aircraft safety assessments. The move away from prescriptive regulatory requirements means each specific aircraft configuration must be addressed. There are no generic lessons to learn from past aviation accidents and incidents.

Although, I think these puzzles can be solved it’s a huge leap from here to there.

More H2

I think this came at me both ways as a schoolboy. Both from chemistry and physics. In our 1960s chemistry lab, Bunsen burners, flasks and array of hazardous substances were the norm. Physics seemed more cerebral. Still, the hands-on side of teaching still meant some practical experimentation. That’s the part that most engrossed me.

Electrolysis starred in two mostly harmless experiments. The colourful one was about copper sulfate[1] and the other was about splitting water into its component parts. Getting Oxygen (O2) and Hydrogen (H2) gas by electrolysis[2] is mighty simple and one of those wonders of nature.

Electrolysis is a way of producing carbon-free Hydrogen from renewable and nuclear resources. Despite the apparent straightforwardness of the process, it’s quite tricky to industrialise on a large scale. One key factor to the future use of Hydrogen is getting the cost per Kg down[3].

Let’s presume that this is a solvable problem and cheap and plentiful gas supplies will be up and running by 2030. That’s not so far off given its 2023. There will surely be a market for ample supplies given the multitude of applications for Hydrogen. Will it be a global market? It needs to be.

It’s a talking point. Hydrogen fuel is one of the viable fuels for aviation. Generating power and returning it to water in the atmosphere is an attractive idea. The process meets carbon-free ambitions even if it does have lots of complications.

On average, a Boeing 737-800 uses about 5,000 lbs (2268 kg) of conventional fuel per flight hour[4]. Cryogenic Hydrogen has lower energy density. That means much more on-board fuel storage will be needed to go as far or fly as long as a current day common commercial jet aircraft.

Designing an aircraft configuration that can accommodate these facts can be done but what of the space that remains for the payload? As it does today, on-board fuel storage will need to meet stringent safety requirements.

Adding this up, it may not be the technical issues that make this difficult. Although they are difficult the technical issues can be addressed. However, will the overall package that results be economically viable? If costs are increased by a factor of, say 5, will this provide for a commercial air transport system that is like the current one?

We may have to accept that carbon-free flying reverts to the 1960s[5]. What I mean is that, instead of low-cost flights hopping here, there, and everywhere for £100, the future maybe one where long-haul flying is a relative luxury or an expensive business need.

ULEZ 2

It’s not the first time I’ve experienced poor air quality. It’s a wonderful city but, on certain days of the year, the air in the German city Cologne is unpleasant. It can be stagnated, stale and dirty when the weather’s hot and there’s no wind blowing.

It was compulsory. You get a fine if you don’t have one. I remember getting a green environmental badge for my car[1]. This is a scheme by which the most polluting vehicles are banned from the central city. Introduced in 2008, initially vehicles were not banned but everyone had to have a coloured badge. These were red, yellow, or green depending upon the type of vehicle. Now, only green environmental badged vehicles are permitted to enter a prescribed city zone.

Yesterday, I drove from Reigate in Surrey to Croydon. Purley Way in fact. That’s a part of the main A23 road in the London Borough of Croydon. I now wonder at my sanity in doing so. The traffic was abominable. Purley Way is a mass of shopping warehouses, tarmac, and suburban sprawl.

What’s visible is the provisions for the introduction of the Ultra Low Emission Zone (ULEZ)[2] at the end of the month. Cameras and signs. This doesn’t ban dirty vehicles from London, but it does charge them a £12.50 daily to drive into or within the ULEZ zone. 

So, here are two different approaches to addressing poor air quality. The German one doesn’t require extensive infrastructure, but it does mean additional policing. The London one is more permissive but at a price. Collecting money from polluting vehicle owners to pay for cameras, enforcement, and publicity. Both require signage to warn drivers of the zone boundaries. Both have their detractors who object to any kind of restrictions.

To me, the problem of poor air quality can not be put on the back burner. You don’t need sensors and precision measurement to know that the problem is huge, real, and persistent. Even in my small Surrey town, the marked difference between days of traffic jams and empty roads is so evident. In the middle of COVID, I walked the High Street of Reigate, and the air was as clear and fresh as a Cornish village in winter. This week, with road works underway the town has been one big traffic jam and breathing the steamy air walking the pavement is not nice. Health suffers and it’s not just the environmental damage.

The utility of the internal combustion engine has seduced our communities. Now, the balance between the benefits of driving and the freedom it once symbolised has tipped. The sheer mass of vehicles in urban environments and their daily impact is so damaging that restrictions must be mandatory. There’s no turning back.

In Cologne, these changes are particularly pertinent. It could be said that the whole ball started rolling in that city. In the district of Deutz there’s a monument to Nicolaus August Otto[3]. He was a German engineer who successfully developed the internal combustion engine.

Pathway

Conversation drifts across a table. “What do you do?” It’s a classic conversation starter. Maybe “Where are you from?” comes up just as often. It’s those basics about identity that either bond us together or throw us apart. Or at least tigger certain ingrained responses.

In a society, like ours that has a long tail of class-based judgement, these questions have greater implications than elsewhere. In of itself that is a questionable remark. Leave the UK and similar markers create stereotypes that are easily recognisable. US comedy is full of them. For fans of the classic series like MASH[1] or Frasier[2] they are there is spades. Situation comedy often depends on misunderstandings and social tensions.

Anyway, I’m writing this when it comes to mind what a big gulf there is between those of us who had “desk jobs” and people who worked far more with their hands and wits. The labels of administrator or artisan can be stamped out so easily in British society.

A conversation went like this – I was a coach builder. I built lorries. I could never have done a desk job. My response was – I was lucky. Sometimes, I sat at a desk under piles of paper. Or in front of a keyboard. Sometimes, I travelled to, just about anywhere, where they built or flew aircraft and got to deal with real hardware. But however much there was an overlap between us two seniors at a bar, there was still a gulf that was probably born of a dividing line that was drawn when we were teenagers. Streaming people away from academic study was a grading system, certainly in the 1970s.

You might say that these traditional social barriers are a thing of the past. They are not, are they? In fact, in powerful places the line between people with real lived experience in craft or public service type roles is growing. Take a cross section of Members of Parliament. How many can count an experience of working a skilled trade or hands-on time doing something useful?

The Oxbridge mafia is as in control as it ever has been. Although recent examples from that background should be enough to put people off. The leisurely stroll from Philosophy, Politics and Economics (PPE) to the green benches is so much simpler than any other pathway.

I love the revitalisation of apprenticeships[3]. However, that word now means something different from what it once did. There weren’t such notions as intermediate or advanced apprenticeships in my time, although they were implicit. Just a few found a sponsor and a pathway to a degree course on the same level as those who stayed on at school.

As much as providing new pathways the social context still matters. Elevating the status of apprenticeships matters. This is a first-class stream. From it can come future leaders.

Local air

There are cases of synergy. That’s where aviation and local authorities have a mutual interest. This often centres around the economic prosperity of an area. Relationships can be complex, difficult, and fraught with volatility. There are plenty of housing and industrial estates that cover the ground of former airfields. Like the railways that closed under Beeching’s axe[1].

Public interest was dominant 50-years ago, but privatisation dramatically changed relationships. Sustaining profitability through good times and bad have proven to be more than some locations could support. There’s so many combinations and permutations but fewer and fewer active commercial airfields in the UK.

London Manston Airport is an airport that only just clings on to existence. In 2013, the Welsh Government acquired Cardiff Airport. So, some aviation facilities have returned to public ownership and run as an arm’s length business. A few airports are given support to ensure connections exists between remote parts of the UK. Highlands and Islands Airports is an example.

Advanced Air Mobility (AAM) is coming. This is the extensive use of electric vertical take-off and landing aircraft (eVTOLs). AAM is an innovative concept that will require Vertiports and integration into busy airspace. To make the economics work a lot of routes will be in, and over urban areas.

My view is that AAM will only succeed in the UK if aviation and local authorities come together and embrace it. That is going to be a massive challenge whatever national government does.

In the case of local authorities with a mission of protecting the interests of residents this has often meant objecting to aviation developments. I go back to proposals of 30-years ago to make Redhill Aerodrome a feeder to London Gatwick Airport[2]. This was well and truly shot down by local interests. In fact, rightly so given the complex twists and turns it would have made in the airspace.

AAM needs the harmonisation of standards to ensure interoperability anywhere in the country. There are one or two UK local authorities that are already embracing the potential opportunities of this new form of flying. Coventry City Council is taking on the challenge[3]. It’s welcoming the development of the ground infrastructure for “air taxis” and delivery drones.

By the way, my view is that introducing the subject as “flying cars” or “air taxis” is not a good idea. This creates images from science fiction that may not resemble the reality of these new air services.

Over the Horizon

Reading Anne Corbett’s article on the Horizon Europe research programme[1], I’m struck by the one step forward and then one step backward walk that the UK is taking. The politics of the moment leaves a UK Prime Minister (PM) dancing on a knife edge. Afraid to fall to the right or to the left of his own party. Having been part of an extremely destructive period in British politics, Rishi Sunak is attempting to re-brand the Conservatives with a colour of nationalism that’s designed to be anything to everybody and as variable as the wind.

From the start of the year, Rishi Sunak has made five promises[2] on economy, health, and immigration. The one on the economy is steeped in blandness. This is presumably to claim success regardless of the situation in the run-up to the next UK General Election. If a PM, of any political party, didn’t want to grow the economy, create better paid jobs and opportunity across the country there would be something distinctly wrong. A wish is fine but what about actions?

I have to say that it’s good to see a UK PM that’s 20-years younger than I am. Particularly when the US is playing out a game of geriatric musical chairs. Russia being plagued with the politics of generations past. China’s building global influence. And to top it all the Earth feeling the impact of climate change like never before.

This why I have such difficulty in understanding Sunak’s attitude to working with our nearest neighbours and closest allies. We have more common interests now than we did in the 1970s when the UK first joined our local trading block. I’m sure the zealots can’t see this fact but undoing the last 40-years is not a good way to forge a future. We can do so much better.

Culham is known for its Centre for Fusion Energy[3]. Its work is collaborative. It needs to be, given the huge costs of working in the field of fusion energy. That’s the way the Sun generates its energy. Here’s an example of the UK being a focal point for European fusion research. Post Brexit, like the problems other research institutions have faced, some researchers returned to continental Europe.

The idiocy of de-Europeanisation serves no one. It’s a residual of discredited political thinking. A Government doesn’t need to advocate re-joining the European Union (EU) but they do need a whole new positive approach to working together with European countries and institutions. Research is at the core of our common interests.

ULEZ

Londoners in all Boroughs need clearer air to breathe

Oh yes. London has an air quality problem. It’s not the only city by any means. My recent trip to Cologne left me in no doubt that cities must address this problem. It’s an insidious hazard. It’s not so – in your face – as noise or water pollution. We’ve this human capacity to normalise bad things. Much to our detriment. Air quality becomes most evident when you move from a place of bad air quality to a place of good air quality. Then the difference becomes acutely noticeable.

Last weekend, I was in the West Country. Way down the A303. The difference is quite striking.

Last evening, I was traveling on the Tube to get to the Albert Hall. The difference is quite striking.

Whatever you may think about the implementation of the Ultra Low Emission Zone (ULEZ) in London, there’s a need to do something drastic.

Expanding ULEZ across all London Boroughs from 29 August 2023 is getting a lot of political attention. No doubt some of this is whipped up purely to punish the Labour Mayor. However, the dilemma is clear. Penalising a lot of people who are not directly feeling the discomfort of poor air quality is inevitably going to cause a stink.

Now, we shouldn’t get disproportionately agitated. That fact is that poor air quality is killing people is not in question. The fact that a small fraction of vehicle owners will be made to pay is not in question[1]. The balancing act between reliving an unacceptable situation of harm and causing minimal economic pain is a tricky one. It would be a tricky one for whoever was in power.

My view is that measure that force people to change their vehicles should be accompanied with a practical scheme to compensate them for significant financial losses. Or that the emissions thresholds set should take account of the natural turn-over of vehicles that takes place in normal years. The political controversy of the moment is much because of the speed of change and its coincidence with a cost-of-living crisis that is very real.

Londoners in all Boroughs need clearer air to breathe. But London doesn’t sit in isolation. Afterall the Borough boundaries do not track urban boundaries. Parts of adjoining areas are equally urbanised, and the air doesn’t know about administrative boundaries. The M25 motorway doesn’t do much for air quality, that’s for sure. So, hearing of the London Mayor doing battle with adjoining areas is a bit sad. Solutions need to be negotiated with all impacted parties regardless of the politics.

By the way, I’m not impressed with communications from Transport for London. I clicked on an e-mail sent to me on the above subject and this came up: “This link has expired. Please contact the sender of the email for more information.” Thanks a lot.

[1] More than 4 out of 5 vehicles meet emissions standards, but if you use a petrol vehicle over 16 years old, or a diesel vehicle over 6 years old, you need to check it.

Energy Policy

Saint Augustine’s early life was not what we associate with a saint. As a young man he prayed “Lord, make me chaste (pure) – but not yet!” Just now that’s the way, I fear, we are thinking of the environment. Global, national, or local. It’s total human but it needs to be fully recognised for its downside. Yes, we would like to do more to restore our environment and fight climate change but we’d rather it happened tomorrow. Tomorrow, tomorrow.

The instinctive urge to put-off decisions for what appears to be an easier life now rattles down through history. The lesson we might learn is that this approach is generally a bad way of going about thing if long-term success is the aim. Civilizations have ended because they failed to change.

This blinkered approach could be called political expediency. It’s at the core of what has become political populism[1]. The drive to persuade an electorate by retreating from commitments and heralding jam today. This fits our social media saturated public debate to the tee. I want it, and I want it now. The future will look after itself.

It’s a sad philosophy. I say that because the premises is that we may as well live well today because we have no control over what happens next. In populist terms, that’s put down to an imaginary conspiring elite that will inevitably win regardless of what you do. Truly nonsense.

That might have been true in the stone age but its far from true in the 21st Century. In reality, and on average, individual citizens have more choice than they have ever had. I say “on average” because there’s a billion people in the world who still live on the breadline.

Anyway, my point is that putting-off environmental measure is foolish. I’m reacting to a Conservative Energy Minister, has said that the UK government will “max out” remaining reserves of North Sea oil and gas[2]. I’s almost as if the Minister thinks this has no impact. That’s other than short-term political gain amongst climate sceptics and right-wing newspaper owners.

If the target for Net Zero is – yes but not yet – there’s virtually no hope of achieving the goal. Events being what they are there will never be a perfect time to stop using fossil fuels. I’m in agreement that the rundown of fossil fuel use should be graduated. However, putting off real change doesn’t make change easier. In fact, it makes change harder.

In the run-up to a UK General Election the possibilities for policies of self-harm are all too evident. A Conservative Government desperate to cling on to power will wriggle and produce contorted justifications for delay. It’s a basic instinct.

I’m not saying that we should all become zealous exponent of hairshirt policies. What is desperate is that we don’t become side-tracked from practical measures that can be practically taken. Taken now.

Work as though everything depended on you, and the choices you make. That needs to be true of Government Ministers as much as every one of us[3].

Thumbs down to British Conservatives

It has been a morning when one thing is certain. Real votes, in real ballot boxes give an indication that British opinion polls are not so far off reality. Conservatives got a pounding when voters expressed their preferences. The only thing to hold back the tide was in Uxbridge and South Ruislip, where the local issue was squarely London’s plans to expand its Ultra Low Emission Zone (ULEZ)[1]. 

The Liberal Democrats won in Somerset and Frome by a huge majority. The Labour Party won Selby and Ainsty with a significant swing. Prime Minister (PM) Rishi Sunak’s Conservatives are soundly on the back foot.

These seats in the House of Commons (HoCs) became vacant as Members of Parliament (MPs) stood down. In these cases, these by-elections have taken place before a soon coming General Elections (GE). Traditionally, that means there’s an element of protest in by-election results that is often more locally focused than in a GE. However, as Tip O’Neill, a former Speaker of the US House of Representatives, was quoted as saying “all politics is local”[2].

The UK Parliament’s HoCs doesn’t sit again until September, but it will have 3 new MPs when it does.

The British economy is underperforming, its health service is struggling, and the cost of living is punishing a lot of people. So, there’s plenty of work for a government to do, even if they seem to have run out of ideas, momentum, and talent.

In terms of the bigger picture there’s a sign that green issues can present politicians with a double-edged sword. On the one hand voters genuinely want to see progress towards greater sustainability and on the other hand they don’t want measures forced on them that make them poorer. Here’s a challenge to all the political parties.

Now, former London Mayor and PM Boris Johnson has gone back to scribbling for the tabloid newspapers and his political style is heading for the dustbin. British Conservatives are floundering with a national identity crisis. Although the Labour Party should be pushing at an open door, there’re plenty of obstacles that remain in their way. For the Liberal Democrats the news is universally good. They have reestablished themselves in their West Country heartlands.

We are only halfway through 2023. It’s been more than a year since MP, and former Conservative Government Minister Nadine Dorries has spoken in the UK Parliament. She did say she would step down but, so far, when this will happen remains a complete mystery[3]. Being an MP should be a full-time job and not just a badge of status. The people of Mid-Bedfordshire deserve better. So, we await her next move on this subject.
