More specifically, they were grounded by a non-functional iPad App they used to check their flight plans, and weren't carrying paper backups.

Let's reflect on the fact that a major freight and passenger hauler was relying on the Cloud and a personal computing company for navigation - and by glad no body was hurt when that went belly up.

Not to call you a luddite but...

This kind of thing has been going on for a while and is a MASSIVE cost saving - the kind of paper backup's companies used to rely on is a) expensive and b) Labour intensive (and in the case of Airplanes where extra weight costs more fuel also HEAVY)

The real issue here is one of Software testing, speaking as an insider who has been migrating the company I work for into the cloud (Microsofts in our case), the cloud has led Software engineers to push updates out far quicker but with less testing simply because their customers are always connected and thus will all update at once - in this case the glitch was with a piece of software provided by boeing, I would hazard a guess that they had just pushed an update out which has "issues".

Well, my belief that relying on computers should never be the only option available to those operating heavy machinery has been reinforced. Tech's great, and we should use it, but until it become's fool-proof we shouldn't be completely ditching the old methods in case the new ones fail.

What if the Heavy Machinery they are operating are essentially a computer to begin with?

Modern planes are essentially flying computers - hell most modern fighter planes cant even fly without the computer, if it breaks they literally fall out of the sky.

This is also true of modern cars - mine cant start without its onboard computer.

The simple truth is Computers are part of almost everything we do today and "clinging" to old methods with serious problems simply because they work is a really bad idea - using these old methods as a back up is still valid (and what the pilots in this case did... stupid story really)

I retract my doubt of tech but I retain that there should have been a backup.

I'm a big believer in backups and safetys and these guys were caught out without one. The least they could have done is had a backup ipad, or better yet had the documents on a cheap e-reader or something.

I'm not sure whether I would use cloud-reliant apps on an airplane, make them work offline and give them a spare in case the first one has a failure and most scenarios should be unproblematic.

I disagree - Id say the story shows they had a very rigorous safety system in place - the pilots all checked their systems before takeoff and upon finding a fault canceled the take off until paper copies could be produced (the fault in question was with software not the actual Ipad so any backup Ipads would have had the same fault)

We should be praising American Airlines for having such a well thought out and executed system instead of chiding them for reliance on technology.

The really interesting question should be to Boeing about why they pushed out a glitchy patch to a safety critical piece of software

The software in question is not cloud reliant - it is designed to work offline (according to Boeing's website) - it seems to work by downloading the maps while the plane is at the gate and connected and then running offline while the plane is in the air - id hazard a guess that the problem was in a failure to download the maps (since the article mentions the pilots having to return to the gate to fix the issue)

You completely missed the point.

The flight plans should be on the plane's own internal computer, which should be receiving encrypted data from American Airlines' own servers this would, among other things, prevent the update issue you mentioned. The Cloud is all well and good if you're sending people weather reports or news but Civilian Airlines should have the same sort of fully internal systems as the military does, you shouldn't be using a third party like Apple to actually run the system.

Hmmm that is a interesting point but really its just a shift of whose cloud you use - your own (in which case you are responsible for maintaining a large array of very expensive computers and a complicated network) or a third party who has dedicated a large amount of resources to maintaining an immense number of very expensive computers and is letting you rent a part of that at a fraction of the cost.

again from experience the Third party option wins out in every way - primarily due to scaling.

If you are maintaining your own cloud in order to add extra resources you need to add more computers - if you are using a third party you simply rent more resources.

If you no longer need the extra resources you are stuck with expensive computers if you are hosting and will need to go through the costly process of removing and recycling them. If you are renting you simply reduce your allocated resources...

I am not saying using third parties is flawless but generally its far more cost effective and reliable (Hosting companies will spend a lot to make sure their cloud doesn't go down- and if it does they are liable not their clients)

Well, I made a somewhat generic statement since some people mentioned that but the article doesn't indeed. It just says the app was failing due to duplicate data and they had to re-download it at the gate once the error was fixed.

This will be a non-issue once the planes are drones and fly without pilots.

Its inevitable really - the planes already fly themselves with Human oversight so its only a small step to remove the pilot entirely...

I suspect they wont go all in however and the first move will be to remove the Pilot from the plane and have them instead connected like the current Reaper drone pilots (ie sitting in a secure facility in a centralised location), they still get the benefit of "trust" then - as this thread shows some people just wouldn't trust a machine without any Human oversight...

Yes, I'm aware of the problem - reading over your post I see that the main plank of your argument is cost. Now, cost is certainly important, even for the military, but the reality is that reliability is much more important for something life this, and the ongoing cost of renting the service is usually more than the cost of running it yourself, certainly for something like a large airline. Reliability is also not great - going back to the military thing - I once stood guard in a guardroom with a broken armoury alarm. That meant that it was impossible to know if someone was braking into the armoury, it was an old camp without CCTV. Why was it broken? Because the German-based company the British Army was renting their own camp from hadn't fixed it.

You really underestimate how much Clouds cost to build and operate - these are MASSIVE arrays of very powerful computers which require constant cooling.

Think about it this way for second - you run a Business which requires a large amount of computing power 5 days a week - if you buy your own machines 2 days a week you will be paying upkeep on machines you are not using. If you Rent you pay for what you use.

On reliability - if you buy the machines you have to maintain the hardware, the area that houses the hardware, the network that the machines are connected into and all software installed.
If you are renting you have a company that is reliant on the cloud working to make its money at your beck and call to make sure everything is Ok... all you need to do is make sure your internal network can contact the external cloud.

so on the Rent side of things it is both A) far cheaper and B) far more reliable.

The only benefit you can gain from controlling your own cloud is the security of knowing all data is handled in house - you would be surprised by the number of business that don't care about that... especially when you consider how difficult and expensive it is to maintain a secure network as Sony as found out...

Another point where most Germans and most businesses break the law.
If the government interpretes the privacy laws strictly, then every german person/company using cloud services to put important data there would have to go to the cloud provider personally and check the data security measures to see whether they are compliant with our data security laws. You can probably imagine how many people or even companies here do that and how many actually put data into the cloud.
Our government has been kind so far and decided not to jail us all.

If you think that's funny consider that clothing companies which should check their suppliers for the use of child labor also hardly do so, John Oliver just had that topic. The EU/US is an unregulated banana republic really, no wonder there are failing iPads on airlines.

This will all change when merciless machines enforce the laws. :robot: :smg:

No, I understand the rationale, and it makes sense for a services company.

Not relevant in this case as airlines operate 7 days a week, 24 hours a day.

If you do a little digging you'll see Sony uses third parties to provide it's customer support, and those third parties necessarily have access to the Network. As to mechanical reliability, there's nobody more obsessive about that than aircraft engineers so it's unlikely that would be lower in-house unless American Airlines fails to understand that their network is actually a part of their mechanical fleet, and not their customer service... which they probably don't.

Bottom line - unless you do it yourself you don't know what the quality is really like.

You could help that a bit by demanding for example a certain level of ITIL fulfillment or some certifications where your provider was independently tested for service quality. And then you have service level agreements and so on. It's not always just a matter of your company having to trust the other company.

Or the CEO of the other company could be your golf buddy/cousin and you just know they can be trusted. ~;)

You still don't seem to be grasping what I am saying so lets put this in context of an airline.

In order to operate their cloud they would need enough resources to operate at their peak times. Lets for argument sake say they have 1000 planes operating at peak times- they therefore have to make sure any hardware they buy can operate at peak efficiency.

They do not always run at peak however - most of the day they will be flying less planes lets say at their quietest they operate 200 planes. This means they are paying for the resources to operate 1000 planes when in fact only 200 are running.

Lets say they expand their business and their peak times now operate at 1200 planes - they now need to procure new machines since their current architecture cannot support the new peak. This means going out buying new machines.

Even with the growth at peak time the number of planes at their lowest remains at 200 - so now they are paying for considerable more resources at down times than they need.

THIS is scalability and is the key reason third party clouds are so attractive - when you are operating at peak the Cloud can distribute more resources to you - they will be far far bigger than you need and can shift resources with ease since they already have them - when you are at your lowest you are not paying for resources you are not using and so are saving a tonne of money.

I want to know whether what you say is relevant here, though.

You speak of clouds very generally, but here's the issue: in the specific case of flight plans, would "vertically-integrating" their electronic management actually cost them anything?

As an example: electronic mail. Creating or licensing an in-house e-mail client, and storing the emails locally or otherwise on company servers, needs an investment of basically $0. This is not a function that it makes any sense to outsource.

Generalizations aside, why wouldn't flight plans be like emails here? I bet you could store a flight plan on a floppy disk. Am I wrong?

Husar
05-01-2015, 03:05
Am I wrong?

Not necessarily, it depends, do they download just the flight plan or a map? If it's e.g. a map with an up-to-date weather forecast then it may not be feasible to run the cloud on your own as you would have to get the maps from the provider anyway unless you also want to run an in-house weather service.

This is one good reason - another reason American Airlines is using a cloud is sadly based on their choice of interface - an IPad.

If you are going to use an Apple product you are probably going to end up using the Apple cloud simple because thats how Apple pushes their business.

I can understand why they picked an IPad as an interface - its light, small and everyone knows how to operate one - but it does limit their options.

Lastly (and this is probably a big plus) the cloud is great for protecting shared data.

If you are emailing or transporting maps you still need to store the data in a centralised location in case of loss (ie a pilot loses the email or disk) - the cloud does that by its very nature (any data is not on any one machine and is usually spread over many so is difficult to lose barring any catastrophic failure).

as to speaking in vague terms about the Cloud... well thats again part of the problem - anything you can do on a Computer you can do in the cloud which means the number of applications is whatever you can think of... Its very difficult to talk specifics without knowing the specifics of what you want to do...

Is the cloud always the best option? No.

For any company running Websites, Database, File storage or needing a large amount of Computing power at infrequent times it is great - but not all companies need that, if all they need is a basic Website and Email its probably far more cost effective to use more traditional means (renting a web server etc).

There is also a cost involved for big businesses which already have large amounts of hardware - they cant just dump it...

There's also a third party where the IT is absolutely critical for their business, such as banks or some stock market traders. If your business depends on having a fe microseconds less signal travel time to the servers of wall street to be able to trade a few microseconds sooner than your competitors, you're not going to outsource your trading to some cloud with servers in Nevada, Vancouver and Greenland.
If you're a bank and your IT is so critical for your business that the time to call a support guy would lose you more money than paying your own support guy for ten years, then you're probably going to keep your critical IT in-house.

As for being specific or non-specific, I just meant that in this particular case we'd need more details to make a somewhat sound judgement on the use of clouds or whatever. Apparently the issue wasn't exactly with the downloading part anyway but with the software having an error once it was to be used offline on the plane.

I doubt there are any individual humans who can make an HB pencil from scratch.

Grow the wood, make the machines (including finding, digging, smelting the metal for the machines), form the graphite.

As for cloud. I doubt there is a single Telco that has dedicated WAN & LAN links to every domestic let alone international airport that an airline might travel to. Then the airline would have to build their own servers, OS and apps. To do it 100% themselves.

I'd much rather the experts and specialists do their own things.

The flight plans should be on the plane's own internal computer, which should be receiving encrypted data from American Airlines' own servers this would, among other things, prevent the update issue you mentioned.

I have a rather unique perspective on this as my wife used to work (up until last summer) for Jeppesen (http://jeppdirect.jeppesen.com/category_template.jsp?catId=cat50&kwpgus=&cid=sem90043849) which is the company that produces all the charts for every airline in the world. She was actually one of their control desk managers who controlled the entire printing process for the paper charts and was involved in some of the switchover to the iPad when it first started being tested.

The first thing to understand here is what it costs to produce the paper charts. Jeppesen has a printing facility here in Colorado that probably still has 100 or more employees, and when my wife left that printing operation ran 24 hours a day 6 days a week. That is expensive, and all of that cost is transferred to you every time you buy an airline ticket. FedEx has several trucks per day that pick up charts, and then they fly them out to the various airlines who then ship them to the various airports around the world. You cannot simply email the file to an airport and let the airport print things locally. The paper these are printed on is 30 or 36 inches wide and can be up to 6-7 feet long depending on the chart. If you look at the pic in the article posted above you will see one stack that has a big rubber band around it, that is one of the charts that folds out and can be 6 feet long. These things a printed on huge printing presses like this one (http://www8.hp.com/us/en/commercial-printers/indigo-presses/30000.html) that cost like $50,000 each. I know when they installed 4 new ones a couple of years ago the setup time and costs were pretty crazy. So the incentive for a better solution is a real one.

When they started testing iPad stuff a few years ago, Apple built special versions of the iPad just for this. Sort of like Blackberry doing special things for Obama's phone. I have actually seen (but not touched) one of them. I am not sure of all the details but these are not retail iPads, and they work on their own cloud system.

When an airline is scheduled to go someplace, they have to have charts for the originating airport, the destination airport, and a bunch of airports in between for emergency landings or other detours (weather, whatever) that cause them to land someplace else. In addition, they have to have not just charts but all kinds of other paperwork for all these destinations. Stuff like terrorist plans and emergency procedures, airspace info and landing patterns, and probably a ton of other things I have no idea about. You can get an idea of what they need by using iflightplanner.com (http://www.iflightplanner.com/AviationCharts/) and just clicking around a bit. Just zoom in on anything you want and you will see a bit of what I mean. Its quite a bit of stuff, and commercial airliners have stricter requirements than private pilots do.

Its all very complicated and the more airplanes, airlines, and general aviation flights there are out there the more complicated it gets. All of these charts have to be constantly updated, printed, and shipped out. And damn near anything can trigger the requirements for charts to be updated. Airport construction, construction around an airport, a tree being planted, you name it. In fact one of reasons for the push to go digital was actually the tsunami that took down the Fukishima power plant a few years ago. Many people do not know it, but the runways at the Tokyo airport moved forcing an update of the charts.

FAA regulations prohibit commercial pilots from flying without updated charts. The reason this was a problem during the Fukishima crisis is because we were trying to ship literally tons of aid into the area. The US government actually called privately owned jets into service. There is a rule that says if the government loans your company money to buy an airplane, they can call that airplane into government service for emergencies. And they did this, they called on United and others to provide planes to ship supplies into Tokyo and support the military operations. I posted this on TWC a few years go, but the short version is that those pilots could not land in Tokyo because of the lack of updated charts and the FAA would not relax the rules for the flights. They ended up landing in Singapore and China and other places, moving the cargo to military planes, and then flying onto Tokyo because military pilots do not have the same restrictions. It was a disaster.

My wife ended up working like 36 hours straight as they updated charts, printed them by the thousands, and shipped them out. FedEx had a truck sitting on the dock running as stuff was coming off the presses and then that truck got a police escort to Denver International where it was just driven straight into a plane with priority takeoff so they could get the new charts into the hands of people needing to fly emergency supplies into Tokyo.

The digital version eliminates all of those problems since once its updated it can be loaded onto one of the iPads from just about anywhere. It may not be perfect 100% of the time but its been running since late 2012 now and I rarely hear of an issue with it, and the paper process is far from perfect as well.
