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.

Electric Flight

Hype has its place. Being positive while buffeted by the inevitable ups and downs of life is purposeful and necessary. What’s not true, and might be the impression, is that electric aviation is easy. When forging ahead to build a future, that is not yet realised, there’s a need to maintain confidence. However, being blinded by the light doesn’t help when it comes to tackling difficult problems. Proof-of-concept is just that.

The big positives of electric aviation are the environmental benefits. Electric aviation is spawning many new types of aircraft and the possibilities of new types of operation. So, there’s no doubt that this is an exciting time to be an aviation enthusiast. What a great time to be in aerospace design and manufacturing. Here we are at the start of a new era[1].

My point is that high power electrics, and their control are not “simple” or intrinsically safe in ways other types of aircraft are not. I know that’s a double negative. Better I say that high power electrics, operated in a harsh airborne environment have their own complexities, especially in control and failure management. Fostering an illusion that the time between having an idea and getting it into service can be done in the blink of an eye is dangerous.

The design, development and production of advanced aircraft power distribution, control and avionics systems is not for the faint hearted. Handling large amounts of electrical power doesn’t have the outward evidence of large spinning mechanical systems but never underestimate the real power involved. Power is power.

The eVTOL aircraft in development deploy innovative design strategies. There’s a lot that’s new. Especially all together in one flying vehicle. Everyone wants fully electric and hybrid-electric aircraft with usable range and payload capacity. So, the race is one. Companies are productising the designs for electric motors of powers of greater than 10kW/kg[2] with high efficiency and impressive reliable. These systems will demand suitable care and attention when they get out into the operating world.

A 500kW motor will go up with one hell of a bang and fire when it fails. The avionics may shut it down, but everything will have to work smoothy as designed every day, not just in-flight but on the ground too. Suppressing an electrical fire isn’t the same as a conventional fuel fire either. To fix these machines the care needed will be great. 1000 Volt connections capable of supplying high power can kill.

Not wishing to be focussed on the problems but here I go. Another major problem is the number of qualified engineers, with knowledge and experience who can work in this area. The companies who know how to do this demanding work are desperately searching for new people to join their ranks.

Educators are starting to consider these demands as they plan for the future. Sadly, there’s not so many of them across the globe who are so foward looking.

The global aviation industry needs to step-up and train people like crazy. The demand for Subject Matter Experts (SMEs) is self-evident. That’s true in design, production, and maintenance. Post COVID budgets maybe stretched but without the big-time investments in people as well as machinery success will be nothing but an illusion.

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.

H2 is difficult

I mentioned Hydrogen as an option for aviation. The use of Hydrogen to either power jet engines or to power fuel cells to provide electricity is a real technical option. Although the person I was talking to was engaged in environmental work, they shrugged their shoulders when I mentioned Hydrogen. They were certainly not impressed by these possibilities despite our agreement on the urgent need for de-carbonisation.

I can understand why there’s a level of cynicisms. On my part, it’s like the X-Files[1]. Fox Mulder was the believer and Dana Scully the sceptic. Broadly, I want to believe.

Today’s, liquid fuels can be explosive in certain conditions. However, it takes a considerable effort to create the conditions whereby a devastating explosion can occur. The Boeing 747-100 that was Trans World Airlines Flight 800 (TWA 800)[2] exploded, broke up in the air and fell into the Atlantic Ocean in 1996. This was an example of a worst-case scenario. 230 people were lost in that fatal accident. Now, the ignition of a flammable fuel/air mixture in aircraft tanks is better prevented by design and operational procedures.

If Hydrogen is to be viable in civil aviation such hazardous conditions will be harder to prevent. A flammable hydrogen/air mixture can be ignited much more easily than conventional liquid fuels. Such dangerous situations can be prevented but the measure to do so will require robust design and stringent operational procedures.

Several development programmes are underway, making practical Hydrogen powered aircraft viable. A range of aircraft configurations are possible. From hybrid generator and electric motor set-ups to combustion-based propulsion. This work is moving from academic research into commercial possibilities.

There little read across between the behaviour of conventional hydrocarbon liquid fuels and liquid Hydrogen. This would be evident in any serious incident or accident scenario. Let us imagine the case of British Airways Flight 38, in 2006, a Boeing 777-236 that came down at the end of a runway at London Heathrow[3]. A significant amount of fuel leaked from the aircraft after it came to rest, but there was no fire. There were no fatalities.

The breakup of liquid Hydrogen tanks or plumbing in such a scenario would almost certainly result in a significant fire. The mitigating impact of that fire is the lightness of the gas. Instead of liquid fuel pooling on the ground, Hydrogen would burn upward. However, any explosion could be devastating.

So, for large aircraft design the provisions to protect liquid Hydrogen tanks and plumbing must be extensive and extremely robust. This would have to be maintained, as such throughout the whole operational life of the aircraft. These requirements would be onerous.

Keeping crew and passengers well away from Hydrogen infrastructure will be a must.

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.

Weight

Projects aiming to electrify aviation are numerous. This is one strand to the vigorous effort to reduce the environmental impact of civil aviation. Clearly, feasible aircraft that do not use combustion are an attractive possibility. This step shows signs of being practical for the smaller sizes of aircraft.

Along the research road there are several hurdles that need to be overcome. One centres around the source of airborne power that is used. State-of-the-art battery technology is heavy. The combinations of materials used, and the modest power densities available result in the need for bulky batteries.

For any vehicle based on electric propulsion a chief challenge is not only to carry a useful load but to carry its own power source. These issues are evident in the introduction of electric road vehicles. They are by no means insurmountable, but they are quite different from conventional combustion engineered vehicles.

The density of conventional liquid fuels means that we get a big bang for your buck[1]. Not only that but as a flight progresses so the weight of fuel to be carried by an aircraft reduces. That’s two major pluses for kerosene. The major negative remains the environmental impact of its use.

Both electricity and conventional liquid fuels have a huge plus. The ground infrastructure needed to move them from A to B is well understood and not onerously expensive. It’s no good considering an aircraft design entirely in isolation. Any useful vehicle needs to be able to be re-powered easily, not too frequently and without breaking the bank[2].

Back to the subject of weight. It really is a number one concern. I recall a certain large helicopter design were the effort put into weight reduction was considerable. Design engineers were rushing around trying to shave-off even a tiny fraction of weight from every bit of kit. At one stage it was mooted that designers should remove all the handles from the avionics boxes in the e-bay of the aircraft. That was dismissed after further thought about how that idea would impact aircraft maintenance. However, suppliers were urged think again about equipment handling.

This extensive exercise happened because less aircraft weight equated to more aircraft payload. That simple equation was a massive commercial driver. It could be the difference between being competitive in the marketplace or being overtaken by others.

Aviation will always face this problem. Aircraft design is sensitive to weight. Not only does this mean maximum power at minimum weight, but this mean that what power that is available must be used in the most efficient manner possible.

So, is there a huge international investment in power electronics for aviation? Yes, it does come down to semiconductors. Now, there’s a lot of piggybacking[3] from the automotive industries. In my view that’s NOT good enough. [Sorry, about the idiom overload].

Safety is poltical

It’s a surprisingly controversial statement. It’s particularly difficult for those working in traditionally technical specialisations to come to openly acknowledge “politics” in their work. By raising the subject, it’s almost as if one had stepped in something unpleasant.

I recall the period when a new aviation agency was being established. That’s in the dawn of this new century. EASA, the European Aviation Safety Agency came into operation in 2003, but the debate about its shape and form occupied many of the preceding years. Politicians, administrators, technocrats, and industry were vocal about the direction to take.

The impact of liberalising European civil aviation, that stated in the 1970s, was primarily a political drive. It envisaged both a commercial and social benefits. Separating the operation of aviation from the vagaries of political personalities seemed to offer a future that would be led by the customers needs.

The general acceptance that State control of businesses, like airlines and manufacturers, had a stifling effect, limiting innovation and opportunity was questioned but not so much by those with the power to make changes. Momentum pushing liberalisation was given a boost by the apparent successes of businesses, like Southwest airlines[1] in the US. Freddie Laker had a big influence in the UK[2].

In these decades of transformation aviation safety has always been heralded as a priority. Whoever is speaking, that’s the line that is taken. Safety is number one. What industry has experienced is a decades long transition from the ways and mean of trying to control safety to an approach more based on managing potential outcomes. This is characterised in a shift from mostly prescriptive rules and regulations to other more adaptive approaches.

Back to the proposition that safety is political. There are several ways to address this as an exercise of analysis. There’s a mammoth amount of historical evidence to draw upon. However, my thoughts are more to do with anecdote and lived experience.

Number one is that our institutions are shaped by political decision-making. This is to varying degrees, from year to year, but international bodies, national ministries, administration, authorities, agencies, committees, learned bodies, all depend upon political support. If they do not muster and sustain this support, they will wither and die.

Number two, change is a constant, failures happen but safety achievement depends on a consistency, dependability, and stability. Maintaining public confidence. There lies a dissonance that must be reconciled. Governments and politicians instinctively insulate themselves in such cases and so the notion of “independent” regulation is promoted.

Number three, arguments for liberalisation or intervention do not stop. The perpetual seesaw of cutting “red tape” and tightening rules and regulation may settle for a while even if these are always in movement. This can be driven by events. The proximity of fatal accidents is always a significant political driver. Domestic fatalities, where consequences are borne locally, will have much more impact than similar events 1000 miles away.

Does any of this matter? Afterall it’s a context that exists, de-facto. It’s no good saying: stop the world I want to get off.

Yes, it does matter. Accepting that safety is political helps dispel some of the myths that persist.

A prerequisite to safety success is provision of adequate resources. Constantly cutting a budget has consequences. A blind drive for efficiency that doesn’t effectively measure performance invites failure. Much as lack of planning invites failure. Reality bites.

It’s reasonable to question of investigatory or regulatory “independence” from time-to-time. The reasons for safety decision-making can be purely objective and technical. Questioning that “purity” need not be impugning politicians, administrators, or managers in their motivations. Shedding light on contextual factors can help learning and avoidance of future failures.

Accepting the perpetual political seesaw of debate can help a great deal in meeting safety goals. What this means is the importance of timing. Making a proposal to tighten a rule concerning a known deficiency can meet a stone wall. Making the same proposal after an accident, involving that deficiency, can go much better. Evidence that is compelling can change minds. This is reality.

digital probing

It’s the Japanese knotweed of the digital world.

Advertising, marketing, promotion, selling, I expect some of those cave paintings of ancient men and women were showing-off to the rest of their society. They’d be saying, extra tasty bison if you head on down to this big watering hole. Throw your spear this way for the best results. The communication medium, a rock face isn’t so different from billboards, hoardings and signage that line busy roads. Catching your eye is the aim. Doing it on a busy throughfare is a proven method.

Too much of this can be annoying, distracting and ultimately defeating. Wall-to-wall advertising that’s pushy, gaudy and litters the highway is a nightmare no one wants to see. It’s not just the urban planners that get riled-up when they see streets plastered with garish advertising.

What of the digital worlds we inhabit? It’s clear they’re no exception. A great deal of the money to be made digitally comes from advertising. My beef here is with the saturation questioning that this industry uses to accumulate data. The bombarding of people with questionnaire after questionnaire is as annoying as any gaudy poster. Survey after survey pops-up as soon as you give away your e-mail address in any purchase. “We’d love to know more about the experience you recently had……………”

It’s one reason why I always refuse any request made at a till in a shop. Occasionally, shop assistants will look offended. It’s as if you have slighted them, is some incomprehensible way. It’s no good them saying they can reassure you that your data will be “protected”. Such reassurances are meaningless.

There are so many examples of data held securely and in line with data protection rules being hacked[1][2][3][4] and spread around like confetti. Compensation after the event is not compensation for the aggravation.

Making purchases it’s inevitable that we will give away data. Few of us read the terms and conditions under which we give away our data. There’s an expectation of “protection”. The conveniences of digital transactions are traded against the risks of losing vital personal data.

When it comes to advertising there’s no necessity. Unless there’s some form of inducement. One came into my in-box saying, “win a £10,000 holiday”. I did what I normally do – deleted it. I find such hooks like “This survey will only take a few minutes to complete” as annoying as improbable competitions and insincere thanks.

I don’t suppose I’m eccentric in disliking all this unrelenting digital probing. It’s clutter. It’s invasive. It’s the Japanese knotweed of the digital world.

UAP

….none of us are familiar with the variety in shape and size of flying machines currently being designed and developed for general use

There was a time when anyone raising the issue of the potential for an asteroid to send humans back to the stone age was mocked and derided. Anyone bringing apparent sci-fi plots into Parliament was jeered. Now, the subject is studied with intensity and considerable resources. The probabilities of Near-Earth Object[1] (NEO) impact is calculated, and small asteroid and comet orbits are monitored in detail.

Really bad films, like the one starring Bruce Willis have a lot to answer for. That space between fiction and reality gets filled with more than a few eccentrics and conspiracy theories. Trouble is that gives you, and me licence to smirk anytime cosmic occurrences come into discussion.

I must admit I like the term Unidentified Anomalous Phenomena (UAP) better than UFO. They are airborne phenomena, they are unidentified until we know better, and they are anomalous. Although, most reports are attributed to things that are known, even if they are rare events. Some are pooly reported and only scant evidence is avialable.

Discovering all there is to know about such airborne phenomena is a matter of both safety and security. However remote it might seem, part of this is the safety of aircraft in flight. I know of no examples of extra-terrestrial objects colliding with aircraft but it’s not impossible. I’m reminded of that classic picture of a bullet hitting a bullet in-flight and fusing together. It’s from the Battle of Gallipoli.

We might be entering a new era of transparency in the scientific study of UAP. This is a wholly good thing and highly necessary given the coming expansion in the number of air vehicles in flight. If Advanced Air Mobility (AAM) is going to do anything, it’s going to led to an increase in aviators and public reports. For one, none of us are familiar with the variety in shape and size of flying machines currently being designed and developed for general use. It’s likly that red and green lights moving through the sky at night is going to prompt public reports of the “unknown”.

Perspective plays a part too. A small drone close can look like a large airship at distance. As environmental conditions change so the perception of airborne objects can change dramatically. So, what we might observe and confidently attribute to be a drone or helicopter or aircraft in-flight is not always definitive. Applying disciplined scientific analysis to the data that is available has benefits.

Given that our airspace is likely to become ever more crowded, NASA’s study[2] of UAP has much merit. Recognising that resources are needed for this work is a lesson most nations need to learn. We can sit on our hands or giggle at the more ridiculous interpretations of observations, but this kind of reporting and analysis will be advantageous to aviation safety and security. It’s part of giving the public confidence that nothing unknown, unmanaged or uncontrolled is going on abover their heads too.

Happy Birthday EASA

Happy Birthday EASA. 20 years is a good age

For me, it was a peculiar day in July. It was a baking hot Brussels. The sun beat down and the city’s trams were full of sweaty travellers. The interview room was a classic board room style. Modern office, heavy polished wooden table, and heavy black leather chairs. On a hot bright sunny summer day that was not a pleasing formula for a formal interview.

I was surprised at the result. I got the job. A moment in July 2004 became a pivotal moment in my aviation career. Not quite 20-years ago. The European Aviation Safety Agency (EASA)[1] was already up and running in a shared office in a Brussels suburb. It was the bare bones of an organisation in the process of a rapid build-up. Discussion about the locations of the Agency’s eventual headquarters were concluding.

That kicked-off my 11-years in Cologne. I arrived in the city when the tower building was being constructed and as the staff had just moved from Brussels to take up the new headquarters. It was December 2004. Offices, on the 6^th floor of the main building were buzzing. The Agency was small in numbers and running fast to fulfil its new responsibilities.

European aviation safety regulation was going through a major change. Up until September 2003, Europe’s National Aviation Authorities (NAAs) acted as a partnership within the Joint Aviation Authorities (JAA)[2]. A body of rules and regulations and ways of working had been harmonised. However, because of the “club” like nature of the JAA there remained unresolved disagreements, incontinences, and a confusing representation at international level.

The legislation that called for the formation of EASA was set to unify aircraft certification and rulemaking activities and drive a consistency in the application of standards across Europe. It was the start of a long road to build world-class civil aviation safety regulator. It worked.

I experienced the first decade in Cologne. The storming and norming. The extensions of remit and turbulent days when we were finding our way. Several tragic fatal accidents and a least one Europe wide crisis. Now, the Agency is about to start its third decade.

EASA is undisputed as the European organisation that talks to the international aviation community. It works in lockstep with the European Commission. It is an achievement to be celebrated.

Yes, I find it sad that the UK is no longer a member of the Agency. But that doesn’t stop National Aviation Authorities (NAAs) working together in a constructive and positive manner[3]. There’s much to be gained from avoiding the fragmentation and conflicts of the past.

Happy Birthday EASA. 20 years is a good age.
