The $100,000 Device That Could Have Solved Missing Plane Mystery

First time accepted submitter evidencebase writes "How can an airliner simply disappear, leaving no clues? And why do we have to wait until the black boxes are found to learn what happened to Flight MH370? As this article explains, there's no good reason that flight data needs to go down with the plane, because the technology to stream it to ground, from the moment things start to go wrong, is already on the market. It can be fitted to a commercial airliner for less than $100,000. But the industry has decided that it's not worth the expense. Tell that the the families of passengers on Flight MH370."

Does it really cost $100k?

[jonwil]

Or does it cost $100k PLUS the cost of labor and maintanence to install the device PLUS the huge cost of taking the plane out of service for x amount of time while the device is being installed (even if its installed at the same time as other maintanence is done, its still a non-zero cost)

Re:Does it really cost $100k?

[Spazmania]

Yeah, it really costs $100k. Custom Iridium devices of this character aren't terribly expensive, on the order of $500k to $1M to design and $5k-$10k each to manufacture in small quantities. The rest is the cost of putting it on the plane, maintaining it and paying for satellite service.

Iridium is an LEO satellite constellation. You only send the radio signal a few hundred miles, you you can basically point an antenna generically at the sky and talk. It doesn't require the kind of complex engineering that talking to a geostationary satellite from a moving vehicle would.

The report didn't say, but a device of this nature is most likely what was on he air france flight, sending in the maintenance reports.

Nevertheless, $100k is a lot of money. Would the passengers have been willing to pay more for the tickets so that their loved ones would have a slightly better idea where they crashed? Probably not.

Re:Does it really cost $100k?

[Frobnicator]

I'm confused, is it a "huge" cost, or a "non-zero" cost?

Both, because you need to multiply it by planes in service.

A few seconds on Google shows there are around 20,000 registered commercial airliners, and around 145,000 registered aircraft (including commercial aircraft, corporate jets, personal airplanes, military aircraft, and so on.) It doesn't include non-registered aircraft, of which there are many.

But the costs multiply. So when you start with $100K for the device plus installation, you are looking at $14B for the first pass. Then your small annual fee multiplies to perhaps fifty million every year in upkeep and service fees.

If you are talking about a major aircraft like a commercial B777 passenger craft, the installation and upkeep is relatively small. These massive aircraft are expensive to buy and maintain. The amortized cost per passenger over a year's flights is going to be a fraction of a cent.

When you are talking about smaller craft like the super common Cessna 172, the device is going to be about 1/4 of the cost of the airplane. All the little utility aircraft are the most common type of aircraft, even though most of us only associate airplanes with the giant cargo jets and passenger flights.

Ultimately let's assume they are looking around $14B initial investment plus $50M/year continuous cost. All of that money to get a little information once every few years when an airplane gets lost over the ocean. Is it worth it? Perhaps it is worth it for the large commercial passenger airlines, but not for all aircraft.

Come on, let's do some math instead of just guessing at the answer: if a plane seats 200 people, flies 4 segments/day, 300 days/year, and the device has a useful life of 10 years, that's $100K / 10 / 300 / 4 / 200 = about 4 cents per passenger segment. An order of magnitude more than "a fraction of a cent", but still pretty close to negligible.

Re:Does it really cost $100k?

[icebike]

Wait, the sat service is already in place. You are simply talking about another data channel interleaved on the existing data channels these planes already stream back to the airlines and to Boeing/Airbus.

If airlines are going to start feeding passengers internet access they surely have time to insert a few OOB packets for event recording. I believe some of this is part of ACAS data streams.

The flight in question had GPS tracking for flight arrival information.
It went dead the same time as everything else. (EMP pulse?)

Re:Does it really cost $100k?

[gnupun]

Nevertheless, $100k is a lot of money. Would the passengers have been willing to pay more for the tickets so that their loved ones would have a slightly better idea where they crashed? Probably not.

No, $100k is not a lot of money. Consider just the fuel cost: 10 hours flying time by a Boeing 747 consumes 36,000 gallons of fuel. That's around $100k or more.

Re:Does it really cost $100k?

[LeeRyman]

I disagree,

Maintenance schedules are already extremely tight, and there is a great deal of engineering change procedures that would need to go into fitting something like this to ensure it actually works without making the aircraft fall out of the sky (would kind of make the device redundant). Mods are made, but not without extensive rigour and testing.

(And yes, I have worked in an aircraft through-life support industry)

Re:Does it really cost $100k?

[hey!]

What does it matter, on a plane like the 777 that costs $260 to $377 *million* dollars to acquire? That's less than 4 hundreths of a percent of the acquisition cost. 100K$ is peanuts on the scale of costs it takes to acquire and operate a large airliner.

And since it is not, strictly speaking, a piece of *safety* equipment, there's no need to take planes out of service to install it. Just require it on new planes, and maybe retrofit existing large airliners when they're down for major maintenance.

It seems likely to me that the probably reason this device isn't required is engineering conservatism. Before something like this is required, you have to convince people that (a) it's a good idea, and (b) this is a good implementation of that good idea.

Re:Does it really cost $100k?

[amicusNYCL]

Ultimately let's assume they are looking around $14B initial investment plus $50M/year continuous cost.

Why are we assuming that? A Cessna 172 has a maximum takeoff weight of 2400 pounds, while cockpit voice recorders are required on aircraft with a MTOW of over 12,500 pounds (5700kg). Why are we assuming that this technology to supplement a black box is going to be required on aircraft where a black box is not currently required?

This is aside from my initial point of calling out the parent because he sounds like a black box manufacturing shill opposed to any technology that might some day replace a black box, using easily-fungible terms like "huge cost" followed up by, well, it's at least a non-zero cost.

This is also aside from the fact that a private aircraft owner does not lose anything when his aircraft is "out of service". He's not losing passenger dollars. If I open up my Cessna or Piper for maintenance it doesn't cost me anything other than the parts. In short, exclude aircraft with a MTOW of less than 5700kg from your calculation and it will be much more realistic. Figure out how many aircraft are currently flying around with black boxes and you'll at least be in the neighborhood.

Re:Does it really cost $100k?

[Cederic]

How much are those boxes? What's the cost to install them everywhere? What's our likelihood of a lawsuit?

Multiply by the 78 other devices that might save a life one flight in 400 million.

Or just accept that airline travel is already exceedingly safe, and surprisingly cheap, and choose to fly or not.

should a giant plane smacking into the water allow for such a thing.

Technically, yes - see the Hudson river landing for a fine example. But see my point above, and accept that sometimes you hit the sea so hard you die from the impact, sometimes you drown, and sometimes - if you're lucky, just like 28 million other people that day - you land safely at your destination.

Re:Does it really cost $100k?

[cpotoso]

Your posting is close to non-sense. Who is saying that every Cessna 172 should have this device? We are talking about AIRLINERS, and in particular those that go transoceanic routes where radar tracking is not possible. On a 767-sized plane (and above) the $100k cost IS negligible when compared to other operational costs (fuel, crew, maintenance, insurance).

Re:Does it really cost $100k?

[khallow]

Should we remove that equipment, or are we better off with it?

That's the question that should be asked about any such equipment. We have both costs and benefits more or less laid out. The benefit is that it provides better information for the times that planes are lost - when it works. And costs are that it's another critical piece of gear that has to work in order for the plane to fly. That's not just a $100k one time cost.

Re:Does it really cost $100k?

[mjwx]

Costs to acquire are often not the highest costs. Same with this, it may cost $100K to purchase, but how much to keep running?

I read the article, the technology is flawed in two ways.
1, it depends on the instrumentation or pilots detecting something going wrong. One of the leading theories in the AF447 accident was that an instrument was reporting incorrectly.
2. it depends on satellite communication (which isn't cheap) and MH370 disappeared from RADAR and radio communications. What makes you think a dial on demand satellite connection would work.

Besides this, much like the summary the article is full of half baked assumptions, attacks on the aviation industry, emotive language and thought terminating cliche's in the place of fact or at least tests and results. The aviation industry rejected their devices before because they dont add any real value due to the flaws I mentioned above. They are essentially trying to use a tragedy to sell something of dubious value whilst people are too emotional to think critically. I think FLYHT are scum.

Re:Does it really cost $100k?

[Alex Zepeda]

The slashvertisement did mention the technology used in AF 447: ACARS. MH 370 may have been equipped with ACARS as well, but if it was, it would not be transmitting via satellite as there is no sat antenna on the vanished plane (9M-MRO). In fact, Malaysia Air has been pretty cagey about whether or not 9M-MRO had ACARS. If 9M-MRO *did* have ACARS installed, and the information *could have been* received/recorded there's still the question of whether or not Malaysia Air was paying for upkeep. If Malaysia Air (who's been in financial trouble for a while now) was too cheap to pay for ACARS, why would they pay for the slashvertised product?

Hell, 9M-MRO has Rolls Royce engines. Rolls Royce (and likely other engine manufacturers) offers remote health monitoring of their engines. You don't need an additional $100,000 device for basic tracking.

Let's not forget this salient point from the slashvertisement:

Of course, that wouldn’t yield much information if a plane is blown out of the sky by a bomb, or suffers a sudden catastrophic structural failure at cruising altitude. But in those rare cases, conventional black boxes are really the only viable technology.

Re:Does it really cost $100k?

[noh8rz10]

Most people involved in an airplane crash survive the accident.

are you high? did you just drink some sizzurp? why would you think that most people in an airplane crash survive the accident? Note that the only planes that could benefit from this locator are planes that disappear in mid-flight, because if they have a crash on the ground or in take-off/landing, then everybody already knows where it is.

I assure you that when a plane falls out of the sky somewhere over the ocean, the survival rate is not high.

Re:Does it really cost $100k?

[noh8rz10]

we're missing the obvious solution to the communication problem. why not make it illegal for planes to fly over water? then they'll always be in contact with land. sometimes the problem is right in front of you!

[Joce640k]

Can't we just get the copilot to throw the black box out of the window before they hit the sea?

Much cheaper...

Re:Does it really cost $100k?

[Talderas]

According to that link there's an article which helps break data down.

One thing to note is that I didn't get a good definition for what constitutes an accident so the only thing I have to go off of is "fatal accident".

40% of fatal accidents occur during landing. Survival rates were 18% in 1970s and 20% in 2000-2009.
En route accidents result with survival rates of 11% in 1970s and 7% In 2000-2009.

What the data does show is that if you have a serious accident during a flight, your chances of survival are greatly diminished. That makes sense because the forces involved during en route accidents are going to be far greater than takeoff or landing when the plane is travelling at a much slower speed.

Re:Does it really cost $100k?

[Immerman]

Actually, I would suspect an ocean landing to generally have a higher initial survival rate than an overland one. After all you're presumably gliding in at speed, and the ocean tends to be a lots smoother,softer, and less obstacle-filled than land. If both wings fall off and you literally fall out of the sky on the other hand, well then yeah, survival rates are likely extremely low no matter what's underneath you, but that's an *extremely* rare case. Far more likely that you partially lose engines, control systems, or cabin pressure and have to attempt an emergency landing.

not worth it

[rcarsey]

black boxes are almost always recovered. the only thing it would save is a big oceanic search -- how often does that happen?

Re:not worth it

[K. S. Kyosuke]

I also wonder what prevented the COSPAS-SARSAT system from helping in this case. Or is it just that they don't equip the planes with these beacons? That would seem strange to me.

Re:not worth it

[quenda]

Yeah, that $100k is per aircraft. So two billion dollars for the world's commercial fleets. (around 20,000 jetliners)
That's makes the search and recovery of black boxes look cheap. Very rarely is one lost permanently.

Re:not worth it

[amicusNYCL]

Seems the 9/11 planes' were lost too.

Damnit. Just think, if we would have recovered that equipment then we could have figured out why the planes crashed.

Re:not worth it

[quenda]

We are not saying it is unaffordable.
We say the cost exceeds the very rare benefits.

Lat / Long?

[CohibaVancouver]

I can see how a constant stream of telemetry might be cost-prohibitive, but what about a squirt of data consisting of -

- Flight Number
- Lat / Long
- Airspeed
- Groundspeed
- Altitude
- Compass heeding

...sent every five minutes? At least that would give a 'last known' location.

Re:Lat / Long?

[lesincompetent]

Couldn't simply ACARS be adapted to do this?

Re:Lat / Long?

[amicusNYCL]

Something like that already exists.

Re:Lat / Long?

[TWX]

One could even integrate this kind of thing into the mesh network concept, where aircraft and ground stations simply routinely exchange their data as a sort of near-field-communication thing for the skies.

It could work along the same lines as the early shared-bandwidth ethernet model:

• Plane, on takeoff and once away from range of the airport (which could be a predetermined value and could even be unique to any given airport) starts listening, and starts a random count to transmit (like the CSMA/CD negotiation for Ethernet). The aircraft is listening for basic data such as grandparent post outlined.
• If aircraft detects a transmission from another, it simply notes the sender ID and checks if it has previous data on that sender. If it does it simply appends to the log on the sender, otherwise it starts a new log with that sender's ID.
• If there's no one transmitting, the aircraft transmits.
• If the aircraft detects a special node, like a ground-based node, and if no one is transmitting, the aircraft transmits its flight history information, and then transmits the collected information on other aircraft. This could be on a different frequency so to avoid interrupting the real-time data from aircraft.
• When the aircraft lands, it uploads all of the history on itself and on other aircraft to the airport. Depending on the airline or nation, it may then delete the logs of other aircraft or it may hold on to them, but it holds on to its own logs until maintenance clears them. Once it takes off, the process repeats itself.

To me this isn't all that difficult of a concept, though it would require mandatory participation among commercial jets to be most effective. It would also require that the system couldn't readily be turned off either, so that a hijacker can't disable it.

Because some company using a tragedy to peddle their wares that have dubious value and are not even remotely guaranteed to work is closer.

Pot, meed kettle.

FLYHT are scum. Their products have been rejected by the aviation industry because they don't add value but add additional cost (satellite data connections aren't cheap), are just as prone to failure as current methods (relies on instrumentation or manual activation) and have additional points of failure (a dial on demand satellite connection, when a flight disappears from radar and the pilots cannot be raised on the radio and the transponder is gone... WTF makes me think a dial on demand satellite connection will work). And now they're using a tragedy to try to peddle their crud.

I read the article, it's nothing but attacks on the aviation industry and badly used thought terminating cliche's like "tell that to the families". Its the kind of thing an angry pre-pubescent child would write when their parents ground them.

"Tell the families"? Really?

[fuzzyfuzzyfungus]

As much as penny-pinching on safety systems is a bad habit, is the emotive "zOMG, Tell the Families!!!" really the best argument that there is for these systems?

It's been what, over three days now, with an aircraft that disappeared from radar at commercial cruising altitude without so much as a burst of garbled obscenities from the flight crew. Do you think that your family is clinging to those little flotation-device pillows, awaiting a rescue that would have come in time if only for upgraded real-time blackbox transmission?

If anybody derives some sort of comfort from whatever they do manage to find, all the better; but this is all trying to recover data for failure analysis, not survivors.

Now, if you want to justify real-time transmission, check out the amount of (incidentally not paid for by the airline) search gear that has been diverted from Malaysian, Chinese, and other sources to looking for the debris. Whole bunch of ships, airplane and helicopter overflights, diversion of what, 10 satellites? That starts to make the $100k look like savings.

Re:"Tell the families"? Really?

[i.r.id10t]

Part of these resources are being provided by people or organizations or governments who just want to Do The Right Thing.

Some more of these resources are being provided by those who see others Doing The Right Thing and thinking to themselves that "gee, if A can do it I should do it to show I'm just as good at DTRT as them".

And the last little bit are doing it for a positive karma, so they can get away with Something Bad later on...

A positive motivation for "doing the right thing" is the fact that these military crews have to stay proficient at their job. These emergency situations give them practice for the real world without having the dull feeling of a drill. Not to mention the fact that they would have spent the money flying those helicopters, planes, and sailing those ships regardless. The real question of cost is whether they were diverted from another mission of value, or whether they were just sitting in the south China sea practicing their ELINT skills?

Misunderstanding of risk

[DriedClexler]

Tell that the the families of passengers on Flight MH370."

Oy gevalt! This again? When minimizing risk, you have to invest where you get the best returns in lives saved. Obviously, in retrospect, after an accident, you'll wish you had spent infinity on having more safety, but that's the wrong way to think about it.

You should instead:

1) figure out how much you're willing to spend per statistical life saved

2) deploy safety measures up to that point

It's not always going to make sense to keep throwing on all kinds of safety equipment simply to handle every black swan event you can think of -- remember, they do log airplane location remotely and continuously; it's just that that still wasn't enough in this case.

You might as well advocate that planes start giving everyone a parachute, without realizing it makes flight so unaffordable as to push people to less safe modes of transportation.

Comments like these promote a worse understanding of the issues.

It starts transmitting when something goes wrong

[innocent_white_lamb]

This $100,000 gadget doesn't do continuous data transmission. It starts transmitting when something goes wrong, and that's it.

If something does go wrong and there's time for this thing to start transmitting, then wouldn't there also be time for the pilot (copilot, navigator, stewardess) to get on the radio and say "Hello, chaps on the ground. Something has gone wrong."

If it blows up in mid-air or something like that, you won't get anything more with this device than you get without it.

What do you gain for $100,000, then?

$100 grand? Try $300 Million/yr

[Overzeetop]

The fine article states that L-3 (who has a bit of a conflict of interest) says that streaming all data real-time would cost $300M/yr. The mfr of the "glass box" says it wouldn't stream data until there was an anomalous event, and so it wouldn't cost nearly that much.

Who's right? Well, TFA states "Of course, that wouldn’t yield much information if a plane is blown out of the sky by a bomb, or suffers a sudden catastrophic structural failure at cruising altitude. But in those rare cases, conventional black boxes are really the only viable technology."

So you either stream data all the time, or you miss the really crazy disappearances. Which is exactly the ones you WANT this data from. So to the families of passengers of MH370 - we don't know where your plane is because we didn't spend billions of dollars to equip every plane and then spend an extra $300Million a year to run the system.

Oh, and since the transponder that relays back basic information failed on this flight, there's a chance that whatever took it out would have also taken out the full-data relay, and after spending all those billions of dollars we might *still* not be able to find it.

How would this have helped with MH370?

[tipo159]

"Of course, that wouldn’t yield much information if a plane is blown out of the sky by a bomb, or suffers a sudden catastrophic structural failure at cruising altitude. But in those rare cases, conventional black boxes are really the only viable technology."

MH370 was sending data when it disappeared. The ADS-B data can be found on FlightRadar 24. Rolls Royce indicated that it was receiving ACARS data from the engines.

All of this stuff was either switched off or stopped working because of a sudden catastrophic failure.

Re:Higher prices

[Carnildo]

The number of unrecovered black boxes is pretty damn low: in the past 25 years, only one airplane's recorders were lost. The rest were either destroyed in the crash, or deliberately not recovered.

[jtownatpunk.net]

It shouldn't cost that much. Many planes already have data service (run thru satellites) that they sell to passengers. Shouldn't be that hard to tap into the available instrument data and send out a blurp every 10-15 seconds. Doesn't even need fancy 2-way handshaking. Just send the encrypted packets and grab them as they arrive at the NOC. Not a big deal if the occasional blurp gets missed. But, if they never get another blurp from a plane, at least they got the data right up to the point of disaster.

[140Mandak262Jamuna]

They reel you in with that el-cheapo 100K offer, but then you have to sign a 24 month contract. The "unlimited" streaming plan streams at high speed only for 2GB, then it crawls at 128 Kbps. Want really really unlimited, then you pay per GB. Then there are roaming charges. International roaming charges. Then international texting charges. You have to root the device to install WhatsApp. When the contract is up they will do employ high pressure sales tactics to sign on for another two years for marginal upgrades. Original "free" equipment is designed to crap out in 24 months. Stay away from these data streaming companies.

True, $100K may be a lot of money, if it's the price you pay to put a device into your $10K car.

But we are talking about a jet plane that is worth $100M and up.

What is the ratio of $100K to the original plane pricetag of $100M ? 1: 1000

Allow me to put it in the context of your car - Let's say your car's price tag is $10K, What will that device cost you, if it's 1000th of your car ? $10 ??

Cost per use

[spasm]

Ok, according to the FAA there's ~3,739 U.S. registered passenger jets which carry more than 90 passengers (http://atwonline.com/aircraft-amp-engines/faa-us-commercial-aircraft-fleet-shrank-2011). Cost to fit just U.S. registered aircraft with this device would therefore be just under $374 million.

Number of U.S. registered passenger jets which can carry > 90 passengers that have crashed with any fatalities since 2000 is maybe 5 (https://en.wikipedia.org/wiki/List_of_accidents_and_incidents_involving_commercial_aircraft#2000), and the number of those where it wasn't immediately obvious where the wreckage was was zero.

So in the US alone, we're talking close to $374 million dollars to fit out just aircraft that carry more than 90 people, for a return of nothing. I couldn't find a reliable estimate of the number of commercial passenger aircraft currently flying and capable of carrying > 90 passengers globally, but I did see a number of guestimates in the 15,000-20,000 range. Assuming there's only 10,000 currently active passenger planes in the world capable of carrying >90, that's $1,000,000,000 to fit them with this gadget. The number of planes since 2000 which went down with passengers on board which couldn't be immediately located is what? Two? The Malaysian Airlines one now and the Air France one a few years back?

So if every passenger plane in the world capable of carrying more than 90 people had been fitted with this gadget since 2000 we'd currently be running at half a billion dollars per actual use. I can think of a *lot* of uses for half a billion dollars which would actually save tens of thousands of lives. There isn't a single case in the last 20 years where this gadget would have saved a single life - all it can do, at best, is provide slightly faster confirmation to grieving families that their loved ones were indeed dead and here's how it happened. Which is not trivial - I don't mean to invalidate what such news might mean to someone with a loved one who was on that flight - but oh, my, that's a staggering bill to just provide speedy confirmation of a loved one's death for a few hundred people.

Let's NOT tell that to the families

[whistlingtony]

"Tell that the the families of passengers on Flight MH370"....

Would this device have stopped the plane from crashing? No. It would have told us what happened... So, in other words, it wouldn't have helped at all. We'd still be telling the families that their loved ones died. We'd just be able to tell them what happened. Which we'll be able to do once we recover the plane (and we will, be patient, sheesh) and find the black box.

In other words, this device does nothing that we need. It just tells what happend in time for the news cycle to remember there was this plane crash.

Re:Yes.

[CapOblivious2010]

Once again, the free market fails where regulation would succeed - the former can only correct for the future AFTER everyone's dead and un-buried.

Why do you say that? What makes YOU the authority on the "correct" answer? Maybe people are perfectly comfortable with the status quo - after all, it's not like this box would save anyone, it would just help to find their corpses a little sooner. Considering only a few hundred people a year die in commercial plane crashes (vs around 100 million total deaths per year), and the vast majority of those are found very quickly, it's not really that big of a deal. There are probably better ways to spend $100K per plane to improve the flying experience (safer, more comfortable, less TSA, whatever), yet you've suddenly decided that the best thing to do would have been to bump this box (which you never even heard of until today) to the top of the list!

Worldwide, thousands (probably millions) of people turn up missing every year - it's sad, but true. The number of people who would be found significantly sooner by this device probably averages around a couple dozen per year. What makes those people worth spending billions of dollars on?

It's more likely you could use that same money to find a lot more than a couple dozen people by spending it more intelligently. The only thing that makes these people special is that they were rich enough to afford trans-pacific plane tickets, and they're in the news. If you think that makes them more important than other people, then YOU are the one barely attached to human reality.
