Electrics & Mechanics

Yesterday, I wrote on LH2. The potential fuel for electric aircraft of any size. Yes, I’m not just talking about smaller commuter class transport aircraft.

Let me take some anecdotal evidence from the transition that is going on in road transport. Repairer turns up to fix an electric car that will not start. It’s a simple matter given that the car has been standing unused for a long time. The battery had discharged. A quick charge from another battery pack and all is well. Meantime in conversation it’s clear that the repairer hates working on electric cars. I could say, no surprise, they were trained on combustion engines and have been forced to make a transition in technology.

What’s evident here is the apprehension of a person who likely has a mechanical bias towards their work and the necessity to take on fixing powerful electrics. Mechanics, those who love working with moving parts, often have a dislike of electrics and electronics. It’s an engineer’s “feeling” expressed to me casually over the last 40-years.

In fact, it can be the reason that a design or maintenance engineer took the career path that they did. There is a dividing line between mechanical engineers and electrical engineers that is embedded in our institutional, educational, and training systems.

So, there’s two practical human issues to grapple with in a transition:

  1. Propensity of one branch of technically capable people to find mechanical work less fearsome and more satisfying than electrics or electronics, and
  2. Streaming that is embedded in our institutional, educational, and training systems. Qualifications and recognition are often not so multi-disciplinary focused.

I’m not for one single moment making a luddite argument that mechanical engineers[1] and electrical engineers[2] are two tribes that must be kept apart. Far from it. What’s more important is to recognise that transitions are hard.

New electric aircraft are going to demand technical people with a multiplicity of both mechanical and electrical knowledge. The way the engineering world has been divided up in the past doesn’t cut it. Some of our most cherished niches will need to be challenged.

Transitions of this nature always take much longer than is originally anticipated. In a way, that should be such a surprise. It’s a generational change for a community that can be conservative with a small “c”.

This is NOT business as usual. For example, handling powerful 1000-volt electric technology is not for everyone. Removing and replacing cryogenic plumbing is, again, not for everyone. The hazards are clear. The skills needed are clear.

Reorienting the aircraft maintenance engineering world is going to need new plans and programmes. Better start by enthusing people about the change rather than just forcing it.

Hydrogen in Aviation

The potential for LH2 (liquid hydrogen) is enormous. That’s matched by the logistical and technical difficulties in exploiting this gas’s great potential. It offers energy for a means of propulsion that is nowhere near as environmentally damaging as existing means.

Society already integrates hazardous liquids and gases into everyday life. Each one has been through several iterations. It has been a rollercoaster. Each one has been at the root of disasters, at one time or another.

  • We use gas for cooking and heating in domestic settings. Periodically explosions demolish buildings. Leaks cannot be ignored. Harm can be done.
  • We use light and heavy oils widely in transport systems. Periodically intense fires burn vehicles. Care in handling is essential. Harm can be done.

Without having to say it, both above harm the environment. The search for non-CO2 emitting ways of flying is urgent. Here, I’m writing about harm to people. Physical harm. The business of aviation safety.

Often the physical harm is not associated with the design of the systems used but to the maintenance of those systems. Naturally, there was a learning curve. If we look at early versions of those systems, fatal accidents and incidents were far more regular. So, here’s the challenge for aviation. How do we skip the dangers of the early learning phase? How do we embed rigorous maintenance practices from day one? Big questions.

On the first one of these, lots of fine minds are engaged in putting together standards and practices that will address good design. If this works, and it will be tested extensively, the chance opens for introduction to service with a great deal of confidence that the main risks will be managed.

On the second of these, there’s not much happening. You might say there’s an element of chicken and egg. The shape and form of future LH2 systems needs much more work before we can think deeply about how they will be maintained.

I think that’s wrong. It’s old-fashioned thinking. As the industry has often practiced, making the systems first and then devising ways of maintaining them while in-service. That’s yesterday’s reasoning.

Making aviation system maintenance the Cinderella in the LH2 world is to invite failure. This is a situation where advancing the consideration of how the in-service realm could work, day by day, is necessary. It’s advantageous.

Here’s my reasons.

  1. There are generic approaches that can be tested without knowing the detailed design. That can take existing learning from other industries, like chemical and space industries, and consider their application in aviation.
  2. Emerging technologies, like machine learning, coupled with large scale modelling can provide ways of simulating the operational environment before it exists. Thereby rapidly testing maintenance practices in a safe way.
  3. It’s imperative to start early given the mountain that needs to be climbed. This is particularly true when it comes to education and training of engineers, flight crew, airport and logistics staff and even administrators.

Everyone wants to accelerate environmentally sustainable solutions. When they do get to be in-service, they will be there for decades. Thus, an investment, now, in study of maintenance systems will pay dividends in the longer term. Remember, early fatal accidents and incidents can kill otherwise sound projects or at least put them back on the drawing board for a long time.

NOTE 1: I didn’t mention Liquefied Petroleum Gas (LPG). It’s in the mix. Another CO2 contributor. LPG containers have pressure relief valves. LH2 containers will likely have pressure relief valves too. That said, venting LPG is a lot more environmentally damaging than LH2. From a safety perspective they can both create explosive conditions in confined spaces. Maintenance staff may not need to carry a canary in a cage, but they will certainly need to carry gas detectors when working on LH2 powered aircraft. Our noses will not do the job.

Choice

Desperate British Prime Minister (PM) comes out with the line that the future will be troubled and fast paced change will outstrip past progress. Ok, so what’s new? Hasn’t that been the path of the world since the invention of the computer? Acceleration of change is now locked into humanities destiny.

The audacity of the man is astonishing. Having been intimately associated with calamitous failures of the past decade he espouses his unique abilities to keep us safe and secure.

Hell, I thought former PM Boris Johnson had a big ego. Monday’s speech goes beyond ridiculous[1]. When he says: “People are abusing our liberal democratic values” what comes to my mind is the right-wing government he leads.

We all know, it’s reported continuously, how dangerous the world has become. Noone in any major political party would dismiss that reality. That is bar the eccentric, downright crazy and maybe the fringes of the Greens party.

Interestingly, as far as I know, PM Rishi Sunak isn’t a climate change denier, but he doesn’t have much to say on this monumental global issue. When he says: “And in this world of greater conflict and danger, 100 million people are now displaced globally.” It should occur to him that competition for resources in a world where the climate is changing is at the root of this movement. By the way, there are 8 billion people in the world[2]. So, let’s get our reality in proportion. True, the 0.1 billion people now displaced globally is a figure likely to grow in the next decade. But they are not the enemy.

I had to laugh when I came to the mention in the speech of “robust plans”. The thing that has been characteristic of this Conservative period of government is the distinct lack of planning.

The country’s whole relationship with its neighbours was changed without any plan (Brexit). The ups and downs of the COVID epidemic were endured without a plan, other than that which was made up day-to-day. Year-on-year cuts in defence spending have only been reversed in the wake of global events not a plan of any kind. Surely the Conservatives can only offer a – make it up as we go along – way of governing? It’s what they’ve always done. Hence, the slow decline that has afflicted the country.

The PM lapses into a lazy “needs must” argument that sprinkled with Brexit bull****. Shakespeare would have approved. One example, in All’s Well That Ends Well:

Countess: Tell me thy reason why thou wilt marry.

Clown: My poor body, madam, requires it: I am driven on by the flesh; and he must needs go that the devil drives.

Nothing wrong with being positive about the future. As a country we can do great things. What the PM claims is to have a plan. What he hasn’t got is a plan. And if he did have a plan the likelihood of his own side following that plan is absolutely minimal. He only goes where the devil drives.

ID

Photo ID is essential, or your ballot will be denied to you in the UK. You can’t vote in elections. That was the case for service veterans, last Thursday. The armed forces veteran card was not deemed acceptable ID[1]. This card was heralded as a great step forward by Conservative Ministers. It seems they had not thought through the implications of the new ID card.

The Electoral Reform Society pointed out that the arbitrary nature of voter ID rules is a problem.

No doubt to get milk the publicity, Boris Johnson, former PM, praised the officials who turned him away from the polling station where he attempted to vote in the South Oxfordshire police commissioner vote[2]. That inspired one or two cartoons. As you would expect featuring clowns. The legacy of Boris Johnson’s chaotic time in the premiership continues to echo.

News is not all negative on the voting front. The 15-year time limit on the eligibility of British people living overseas has been lifted. They will now be permitted to vote in UK elections[3]. Most interestingly, around 3.5 million additional people will have the right to vote in the forthcoming UK General Election. I wonder how those living in the European Union (EU) will vote.

Anyway, if we look at the results from last Thursday, the Conservative attempt at what could be called voter suppression seem to have backfired. Big time. My view is that we should be making it easier for citizens to vote and not harder to vote. As one joker pointed out, in this Parliament, there have been more cases of MP’s misdemeanours than there have been of voter fraud.

I agree that many of the heartfelt arguments of 25-years ago about ID cards are now somewhat moot. The way we use mobile phones has put paid to those arguments. Big Brother is here to stay. It’s astonishing how much personal information we give away freely, not to the Government, but to commercial entities committed to extracting profits from our data.

Formally proving ID is an anarchic process in the UK. There are multiple means, and they are all confusing or mixtures of one another. What is becoming a fixed point is one’s mobile phone number. So many computer systems send a text message that requires acknowledgement to prove who you are who you say you are. The assumption being that the person with the mobile phone is the person who owns the phone, and its number.

Maybe it is time for one unified and recognised official UK ID system.

Culture

Yet again, Boeing is in the news. The events of recent times, I feel are immensely sad. Now, it is reported that the FAA has opened an investigation into a possible manufacturing quality lapse on the Boeing 787 aircraft[1]. Concern is that inspection records may have been falsified.

A company that once had a massive professional engineering reputation has sunk to a place where expectations are low. It’s not so much that the company is having a Gerald Ratner moment. Unfortunately, the constant stream of bad news indicates something deeper.

It’s interesting to note that Frank Shrontz[2] passed away last Friday at the grand age of 92. He was the CEO and Chairman of Boeing, who led the company during development of the Boeing 737NG and Boeing 777 aircraft. In the 1990s, I worked on both large aircraft types.

A commonly held view is that, after his time and the merger with McDonnell Douglas the culture of the organisation changed. There’s a view that business schools graduates took over and the mighty engineering ethos that Boeing was known for then went into decline. Some of this maybe anecdotal. Afterall, the whole world has changed in the last 30-years. However, it’s undoubtably true that a lot of people lament the passing of an engineering culture that aimed to be the best.

A famous quote comes to mind: “Culture eats strategy for breakfast.” Those sharp 5 words get discussed time and time again. Having been involved in a lot of strategic planning in my time it’s not nice to read. How wonderful intent, and well described policies can be diluted or ignored is often an indicator of decline. It’s that cartoon of two cavemen pushing a cart with a square wheel. One says to the other: “I’ve been so busy. Working my socks off”. Ignored, on the ground is an unused round wheel. If an organisation’s culture is aggressively centred on short-term gain, then many of the opportunities to fix stuff gets blown out of the window.

We keep talking about “performance” as if it’s a magic pill. Performance based rules, performance-based oversight, and a long list of performance indicators. That, in of itself is not a bad thing. Let’s face it we all want to get better at something. The problem lies with performance only being tagged to commercial performance. Or where commercial performance trumps every other value an engineering company affirms.

To make it clear that all the above is not just a one company problem, it’s useful to look at what confidential reporting schemes have to say. UK CHIRP is a long standing one. Many recent CHIRP reports cite management as a predominant issue[3]. Leadership skills are an issue.

Runaway

Real votes in real ballot boxes are the best way to get an indication of where we are in these unsettling times. OK, I admit that the voter turnout for local elections doesn’t match that of a General Election (GE) in the UK, by a long way. However, what you can say is that those who are motivated to vote in local elections are certainly going to make the effort to vote in a GE.

So, the voting trend that has been observed over the last year, at least, continues. The Labour Party is gaining ground. The Conservative Party is sinking rapidly. The Liberal Democrats and Greens are making measured progress. Independents are gaining. Nationalists are treading water. The newcomer, the Reform Party is growing rapidly from a petite base.

If you have any association with, or supportive opinion of the Conservative Party this must be an extremely unsettling time. Yes, a lot can change in the next few months but the political party in power in the UK is steaming towards an iceberg at high speed. It’s the modern-day Titanic of the British political scene. It’s quite sinkable. It’s members running in different directions.

Often vigorously supported by “conservatives” is the British First Past The Post (FPTP) voting system for GEs. As is self-evident from any inspection of its history, FPTP punishes harshly small political parties or political parties whose national support dips below a certain point. Probably for the first time in decades the British Conservative Party looks as if its heading for that fine line whereby it’s devastated by the results of a national election. The political dynamics are different in England, Scotland, Wales, and Northern Ireland. That said, the general trend of decline of the modern Conservative Party is national.

Brexit is a failed past experiment. The Banking crisis of 20-years ago, COVID-19 and so called “woke” don’t cut it as excuses. That’s pure desperation. Agreed, that no one predicted how conflict and war would be such a pressing concern.

It’s an opinion, but I’ll express it anyway, that the public are swept by a mood of discontent. They are soundly fed-up with the British Conservative Party. There’s little, if anything, that can be done about the trend set by this public mood. It’s an abstract concept, the “public mood” and not so easy to quantify or qualify. It’s the sort of thing that we only know by its symptoms.

The tone of language used to describe the Prime Minister (PM) and his Cabinet is one sign. It’s as much to say – who the hell would want his job unless they were barking mad? Putting on a brave face when the trend is set.

Moving away from the Titanic analogy to that of a runaway train[1], the image in my mind is that of a steam train driver frantically pulling every leaver that can be found but nothing changes. The train is going to crash.

T’was in the year of 24. On that old Westminster line. When the wind was blowing shrill. The polls closed. And the party would not hold. And Number 10 came racing down the hill.

I’ll bet someone can do better than me with that children’s favourite.

AAM

This week, I watched an FAAs Advanced Air Mobility (AAM) webinar[1]. The subject was community engagement. AAM could be air taxies but it’s many uses of the new electric aircraft that are becoming a reality. The term eVTOL is used for those aircraft that have the capability of vertical flight. My reflection is that there are several aspects of AAM that need much more attention. Naturally, I’m taking the discussion of what’s going on in the US and thinking about it in relation to the UK.

  • Land Use Planning

Generally, National Aviation Authorities (NAAs) are consultees when it comes to land use planning. They do not determine planning applications. NAAs may well have set out policies and guidance on the subject but they will not be determining the site of vertiports.

It seems to me that there’s little chance that eVTOL aircraft routes will be established without sufficient community consent.  Community engagement has been appropriately recognised as essential. The aspects in play are like those for existing aerodromes. Often for AAM applications proposals are for the use of new locations, hence a concern. Anytime there’s a serious proposal for a new aerodrome the opposition is up and running long before the proposers have got their act together.

The subject is complicated by the mix of public and private ownership of infrastructure. If the intention is to interconnect AAM with other transport services (bus/train/boat/road), then complicated agreements are going to be inevitable. It’s not just about buildings and tarmac but having a trained workforce available is a location dependent issue too.

  • Business Models

I’m about to sound as if I’m securitising the plans of a contestant on The Apprentice[2]. There are plenty of way of losing money in commercial aviation. It’s been a well-practiced art over the years. Great ideas fall by the wayside after huge amounts of money have been expended. Customers are key. People must want to fly the routes available, time and time again. And like London Black Cabs be prepared to pay the fare. Given the relatively small cabin sizes that are on offer these people are likely to be moderately prosperous groups or individuals.

Regular schedules air services can produce a reliable income. Airport-to-airport connections seem like a good bet. Problem there is the conveyancing of weighty luggage. Busy airspace could be a challenge too. That said, with tens of thousands of people at both ends of a route, no doubt some people will choose a comfortable, speedy direct connection.

There are good possibilities for major event driven transport services. Getting to and from a motor race or horse race event or a concert or festival can be hell when tens of thousands of people are all trying to get to and from a location or venue. The numbers may well stack-up to make eVTOL a premium way of dodging the crowds in an environmentally sound way.

  • Batteries, Batteries, Batteries

Everything in respect of aircraft performance depends on power density. How much oomph can you get out of a small, light weigh physical space. Recharge and go. Do it, again and again. It’s as simple as that. Not only that but aircraft battery packs must be affordable and available. Whizzy technology that cost a mountain of cash and can only be use for a few hundred cycles is no use at all.

Power distribution infrastructure must be up to the job too. Who will pay for this is up for grabs. There’s a good case for public funding given that there are multiple uses of enhanced electrical supply. Given the monopolistic nature of power generation and distribution this will not be easy or quick.

That’s only three issues that require a great deal of attention. Not the attention of researchers. Not the attention of academics, Not the attention of political policy wonks. Connecting entrepreneurs and public bodies needs practical stimulus. The possibilities are exciting.

Highways

The last time I visited the city of Baltimore was in 2012. It was the location of the annual seminar of the International Society of Air Safety Investigators (ISASI)[1]. That was when I was representing the European Aviation Safety Agency (EASA) at such international events.

The relationship between aviation accident investigators and regulators are generally cordial. There’s a great deal of work that requires cooperation and good communication. That’s not to say that the relationships between these two vital parts of national and international aviation safety systems is easy. It’s not. My reflection on that fact is that a degree of constructive tension is inevitable and not always a bad thing.

One way of seeing that relationship is that the primary role of an investigator is to make findings to prevent the repeat of a given accident. For a regulator the primary role is to ensure the complete aviation system runs safely on a day-to-day basis. Both organisations have the public interest at their heart. However, their operational context and perspective are different.

Firstly, my condolence to the families and friends of those who perished because of the Francis Scott Key Bridge accident[2]. The collapse victims and survivors had no way of knowing what was to happen on the night of the accident. I use the word “accident”. This was not an act of God, as some commentators would have it. The safety risks involved in the operation of the port in Baltimore could be anticipated.

In the US there’s an independent federal agency that is tasked with such major investigations. Interestingly, it’s the same one as that investigates aviation accidents and incidents. The National Transportation Safety Board (NTSB) is a multi-modal organisation. That is something we don’t have in the UK. Also, we don’t have a divide between federal and state organisations. Since in the UK we have separate independent national Air, Marine and Rail investigation agencies that cover the country (England, Scotland, Wales, and Northern Ireland).

I will not comment on the accident sequence or causes. It’s the job of an independent investigation to arrive at the technical facts. Recommendations will flow from that investigation.

Where a comment may be in order is that there are many locations across the globe where a vital piece of infrastructure, like a bridge being struck by a large container ship is a possibility. I’d generalise that further. When infrastructure that was designed a built 50 years ago meets modern day operational stress there’s going to be vulnerabilities. Yes, the aviation system is not immune from this fact too. It wasn’t so long ago when I read of PDP-11 computer hardware used for air traffic control (now, historic artifacts[3]). I’m sure there are still Boeing 747s, and alike that need floppy disks to update their hardware.

So, the wider subject is operational legacy systems working with modern systems. This is the interface that requires particular care. The safety risk appetite and exposure in the 1970s/80s was quite different from that which we expect upheld today.

Unfortunately, society is often reluctant to revisit this subject. Additionally, there’s the incentive to go for quick fixes and sweating assets. The example I have in mind the so-called “smart motorways” in the UK[4]. I don’t know how many fatalities can be linked to “smart motorways” but I’m sure, sadly, it’s too many.

POST: In time-off I enjoyed a trip out to Fort McHenry and a walk around the places where The Wire was filmed. The Fort McHenry story is interesting given its role in times of war. The British burnt the White House but the navy didn’t get past Fort McHenry in 1812.

Smart

One of the most irritating peak-time adverts on British TV, now, is the one where a fake Albert Einstein wibbles on to a fake dog in a hideously fake humorous manner. It’s condescending and preachy. What on earth the Albert Einstein has to do with household energy meters I can’t imagine. His famous equation is more useful for making nuclear bombs than measuring domestic power consumption. You might think the great man was an annoying Italian computer gaming character.

The smart meter is pushed on the basis that “you can better manage your energy”. I expect that’s true in most cases when they work well. I’ve had one for some time. We recently changed energy supplier. Guess what? In the transition I had to throw away an indicator and replace it with another.

In the news are reports of defunct smart meters causing people concerning problems. Smart meter mode means a meter can automatically send readings to an energy supplier. When they don’t work, lack of meter readings opens the door to energy companies making up bill estimates often to their advantage.

When I informed our power company, I got an education that put me right. Can’t possibly call the whole system a smart meter. No, that would be wrong. So, says the company:

“The smart meter you are enquiring about is actually an In Home Display, the smart meter is the meter on the wall.”

That informative reply reminded me of the Not The Nine O’clock sketch set in a gramophone shop. Foolish householder not knowing that it’s called an In Home Display (IHD). The smart meter is installed on the wall.

I’m in support of energy saving and the role an intelligent meter can play in monitoring the use of domestic energy. What are they trying to do – put me off?

Long gone are the days when meter readers knocked on the door and with a cheery smile jotted down the gas or electricity numbers in the understairs cupboard.

Now, I see the claim is that the “vast majority” of smart meters are operating as intended. That’s good. Those words mean about 88% according to a BBC report[1]. That sounds fine but what about the 12% who are in limbo? That’s not an inconsiderable number of people.

The roll out of smart metering technology started in 2011. There’s a first-generation and second-generation set-up out there in homes. A lot of work has been done to sort out communication problems. However, network coverage is not universal. Those connection issue are familiar to anyone with even the best mobile phone.

The BBC report is right to highlight problems. There ought to be a bigger focus on a plan for maintenance of the system as much as pushing new smart meter installations.

Safety Culture

Civil aviation remains an extremely safe means of transport. That said, any form of complacency must be addressed. It’s reassuring to say the past has been great but what passengers are most concerned about is their next flight. To have the confidence, to think it irrational to be afraid of flying, to look forward to the next journey, we must have a safe aviation system everywhere and all the time.

For any widespread system that has complex interactions between people and technology there’s never a moment when it can be taken for granted. We count the numbers, but safety is not purely an absence of accidents and incidents. Numbers counted are always past events. They have no direct causal influence on what happens next. True, there are factors in past accidents and incidents that will pop up again and again, but every flight is a unique event.

One of my colleagues who was a senior captain in a major international airline always remined me of the fact that, for all that has gone before, flight risk begins the moment an aircraft sets off down the runway with the intention getting to a destination. When the wheels lift off the ground there’s no stopping time. Reliant on the diligence, vigilance, and integrity of everyone who made a flight possible, flight risk is then in the hands of the crew.

The above is perhaps why we talk a lot about safety culture. The whole aviation family has a role to play. The care, professionalism, and watchfulness of every person makes a difference.

This can extend from the drafting of a new component for a new design, that a decade down the line. ends up as a part of an aircraft just about to leave the gate. This can go back to a flight instructors’ message that emphasised a key point back in a pilot’s initial training, years ago. This can encompass the extra care a couple of air traffic controllers took as they changed shifts.

Safety culture comes from caring. It’s that heightened awareness of the consequence of actions. Being alert to possibilities. Both the good kind, and the bad.

Safety culture is a matter for both individuals and organisations. One without the other doesn’t work. Placing a vigilant person in an organisation that doesn’t care is much like placing a reckless person in an organisation that does care. Although this is what I’ve written, systemic problems are likely the ones that are most likely to cause negative outcomes. This is where the role of management has the most impact.

Culture exists in context. When the ways people interact are determined by practices, processes, and procedures there’s an obligation on management to ensure they fit the bill. Drivers are often economic. In a commercial operation that’s no surprise. It’s when that driver displaces the safety imperative then safety suffers. There’s been several occurrences of this negative phenomena in the last year.
