Engine Data Reveals That Flight 370 Flew On For Hours After It "Disappeared"

Advocatus Diaboli writes "Aviation investigators and national security officials believe the plane flew for a total of five hours based on data automatically downloaded and sent to the ground from the Boeing Co. 777's engines as part of a routine maintenance and monitoring program. As part of its maintenance agreements, Malaysia Airlines transmits its engine data live to Rolls-Royce for analysis. The system compiles data from inside the 777's two Trent 800 engines and transmits snapshots of performance, as well as the altitude and speed of the jet. Those snippets are compiled and transmitted in 30-minute increments, said one person familiar with the system." Update: 03/14 11:41 GMT by S : The WSJ has since updated its report to say the data was from the plane's satellite-communication system. However, Malaysian authorities have denied both scenarios, saying neither Boeing nor Rolls-Royce received data past 1:07am (the flight initially disappeared off radar at 1:30am).

There was a recent airworthiness directive for 777-series aircraft about hull skin problems where SATCOM antennas are mounted on the top of the fuselage but it didn't apply to the Malaysian Airlines 777s since apparently they didn't have those antennas fitted.

      The latest reports is that the radios are there and ping the satellites even when they are not going to transmit data.

      U.S. officials said earlier that they have an "indication" the missing Malaysia Airlines jetliner may have crashed in the Indian Ocean and is moving the USS Kidd to the area to begin searching.

The Boeing 777 jetliners are equipped with what is called the Airplane Health Management system in which they ping a satellite every hour. The number of pings would indicate how long the plane stayed aloft.

For starters, "polar" orbits don't necessarily go over the pole (I think "polar" is any orbit with a ground trace that goes north of 60 degrees or so) ; so why would you put your main assets where relatively few of your customers are? Most people, and most ships, are not in the Arctic, or in the middle of the ocean. There are possibly as many ships in the North Atlantic and Mediterranean (~10% of the Earth's surface) as in the whole of the Pacific (50% of the surface). So where do you concentrate your high-bandwidth resources?

      The experience that you get from an Iridium phone (the ones I've seen are comparable to an early 1990's mobile phone - they need chunky batteries for a lot of transmission power!) in continental North America is not going to be typical or average.

      Surely if voice is 'easy', then an at-least-56k-dial-up-speed Internet link should be no problem,

      In Siberia, using Iridium rack-mounted units, we'd count ourselves lucky to get 9k6. And no, we didn't use it for an "internet link" It was strictly for dialling into a mail server with an offline reader. At (IIRC) $7/ minute, you did not spend one second longer than necessary on that link. Part of the daily mail package to the Boss was a second-by-second justification for the previous day's Iridium usage, and if I wanted to use the link (as a sub-contractor to the company with the Iridium), I had to sign a printed receipt for the line usage every time I needed to call our (mutual) Boss.

      It was easy to run up a $200 bill on the phone in one day. We didn't bitch about the associated paperwork. And woe betide the person who received a personal email on the work's account with a megabyte photo attached to it. I'd send photos of rock specimens etc - part of my job - but you choose them *very* carefully.

      We could, I suppose, have got a land line run to the site. It was 85km to the nearest phone exchange, which served about 30 houses and a pipeline pumping station, and the line would have cost ... tens of thousands of dollars to build, and possibly lives to maintain in the winter (it hit -50degC for weeks during the rig up of that camp). And we'd have been lucky to get 2k4 over a line like that.

      Most people don't understand the meaning of "remote location". A couple of jobs ago we had a guy break a leg quite badly. It took 13 hours to get him to a hospital, using an air ambulance. We don't rush so much over equipment.

      OP has it right, but we can add more information. I've been following the discussion over at www.airliners.net where some people know more about this plane's electronics.

      First some back story. The SATCOM system is sort of like your cable modem, or more accurately a cell data stick for a laptop. It's a sort of modem that knows how to connect to the satellites. Like a unprovisioned cell phone it still reaches out and says "can I have service", and then gets no answer. ACARS is an application that runs on another computer in the plane. It's sort of like a "twitter feed" for a plane. Short messages can be placed on it and routed off to other places. Boeing offers a service where the plane reports its health back to boeing using this application. Rolls Royce offers a service where the engines report back to them using this service. Pilots can even send short text messages over the service back to their HQ. The GPS system can send a message with its position. ACARS knows how to transmit over HF, VHF, and SATCOM. It also goes through a cleaning house (think twitter again) who routes the individual messages to the right party.

      Mayalsia Airlines apparently bought the "limited" package of monitoring. As such ACARS was programmed to send no information to Boeing, and only limited information to Rolls Royce. Compare with the Air France crash in the Atlantic where they subscribed to the "full" suite of monitoring and 29 messages were generated. Further, Mayalsia apparently didn't pay for SATCOM airtime, instead letting it report over HF and VHF. If it was far enough out over water these methods would not be within reach of the radios.

      However, the plane still had a SATCOM system on it (comes standard), and it was still like an unprovisioned cell phone saying "can I have service", apparently once per hour. Further the satellites in orbit have directional antennas that cover a particular section of the ground. It appears in this case ACARS was disabled (either intentionally, a small switch in the cockpit) or via failure (fire, or whatever).

      The key detail is that while ACARS and many other functions can be turned off from the cockpit, the only circuit breaker for the SATCOM systems are NOT in the cockpit according to experts. It would require going to the electronics room on the plane which is not easy to reach in flight, and more importantly would not be possible to reach if a individual had taken over the plane.

      So the stories line up. Boeing received no messages as the plane was not programmed to send them any. Rolls Royce received two during the normal part of flight, and then nothing as the system was turned off or disabled. However that SATCOM modem apparently continued, once per hour, to look for service. I guess the US authorities were able to talk to the satellite provider and get logs of it making those requests, and perhaps even narrowing it down to a specific antenna on the satellite.

      On power; the experts say the plane has ~30 minutes of battery in the case of total electrical failure. In flight it also has a ram air turbine (think mini-windmill) that can generate enough power. If it did a "miracle on the hudson" style landing in water and it somehow stayed afloat (being under water even 1' makes the sat signal too week) batteries would only last ~30 minutes.

      The more useful source of data is secondary radar, which relies on transponders. The transponders generate a pulse when they are interrogated - the aircraft doesn't need to know its own location for this to work - the ground station works it out from the time to receive the reply. The transponder can encode a code to identify the aircraft, and it can also encode the altitude (or at least what the plane thinks its altitude is).

      AK Marc: I'm a licensed pilot, aircraft mechanic, and avionics technician, and have worked on FAA radar systems. What you say is completely untrue. Aviation surveillance radar worldwide is RADAR with capital letters. There is no WiFi involved, no AP, nothing like you describe. The system was designed in the 1960s and, except for some incremental enhancements, has been largely unchanged since then.

      It consists of a ground based antenna system that transmits sweeping RF energy beams that bounce off metal objects such as aircraft (and occasionally flocks of birds) and reflect back to the antenna. The radar electronics complex processes digitized radar data streams from multiple antennas and generates a synthesized image, which appears on controller screens. Controllers can see this basic radar "blip" if they choose, although generally it's displayed as a faint background trace to keep the screen uncluttered.

      The transponder system works by sending a coded signal that rides on the radar energy beam. When the beam paints an aircraft, the on-board transponder receiver decodes this as an "interrogation".

      In its most basic form, called Mode C, the aircraft answers the interrogation with a data packet containing the a four-digit code assigned by a controller to the aircraft (which the pilot typically sets manually after receiving the "squawk" code verbally from the controller), and the aircraft pressure altitude. In the more recent Mode S, this packet contains additional data, such as the GPS location, airspeed, etc. Aircraft can overhear each others' Mode S replies and use that information to build an internal model of occupied airspace; this process is the foundation of the Terminal Collision Avoidance System (TCAS).

      The transponder data gets painted on the controller's integrated radar display to make it easier to track targets. This is called "narrowband" mode because a this system can filter out a lot of clutter, leaving the controller with only verified targets to track. But if the narrowband system fails, which happens on occasion, controllers are all trained to revert to an old manual system using paper markers that they stick to their screens to track aircraft.

      All commercial aircraft and many general aviation aircraft use Mode S today, and thus we collect quite a lot of data about flights in progress. In the Malaysian case, the aircraft was in radar coverage, receiving interrogations and responding, when they lost contact with it. Although the actual radar data hasn't been revealed, the sense of what has been shown so far is that the raw radar return, or echo, as well as the transponder Mode C, stopped simultaneously. It's possible that the controllers were not displaying non-transponder returns on their screens, so it may turn out that there was a raw signal for some time. That's the big question that, once answered, will indicate whether there was a deliberate action to turn off the transponder or a cataclysm turned it off.

      There is no parallel with WiFi. WiFi broadcasts are just data packets; radar interrogations are directional energy beams that locate aircraft in distance and azimuth. WiFi broadcasts are no different from the packets the client sends back to the AP: the framing, timing, and encoding is identical. But radar interrogations are tri-pulse trains on a common global frequency, with unique timing to identify the type of interrogation. Transponder replies are at a different common global frequency transmitted in as TDM-encoded data frames. Replies are omnidirectional and only pass data generated by cockpit instrumentation back to the radar station.

      Thus transponder data is only used by controllers for identification and altitude, and some ancillary data. Mode S GPS content in transponder replies is used by other aircraft for TCAS, not by controllers for position information. If the aircraft is outside reflection range, it won't transpond. By definition if the transponder replies to an interrogation, it was because the aircraft was being painted by a radar's "skin" beam, which at microwave frequencies means there is line of sight between the aircraft and ground antenna. The radar echo is guaranteed to make it back to the station because of this line of sight. On an aircraft the size of a 777, very little energy needs to be reflected to generate position data, and I've never seen a situation where transponders don't have a corresponding primary radar blip.

Suppose that the aircraft is at a distance from the radar such that the signal is attenuated to just below the detection threshold. That is the radar can not get a skin paint -- but barely. However, the strength of the radar signal that strikes the aircraft at that range is 4X (in an ideal world; in reality its probably even higher) the strength of the signal that arrives back at the radar receiver. This is because doubling the distance (which assumes perfect reflection; in reality it's not quite that good) will quarter the power.

      Therefore, the transponder can very likely detect the incoming radar signal -- and respond to it -- at ranges beyond which the radar can get a skin paint, since it receives 4X as much power.

      The question, then, is whether the transponder replies with greater energy than the reflection at those long ranges. If so, then there is a zone in which the transponder signal can be detected but the skin paint cannot.

    Let's see, how about the conspiracy of silence regarding the crash of TWA flight 800 back in 1996?
    About a year ago, CNN had six former hands-on investigators who all worked on the original crash investigation.
    All six investigators finally came forward as a group in their retirement to recount how the actual evidence found contradicted the officially announced cause of the crash (officially the 747 fuel tank vapors exploded bringing down the airliner), and how they were essentially compelled to falsify their conclusions by higher administrations.
    I have not seen these six former investigators story picked up (arguably extremely reliable sources), by CNN or any other media outlet since the obligatory CNN lip service broadcast (likely done merely to cover CNN's own ass if the shit hit the fan, so CNN can claim to have actually covered the story).
    It's highly likely the government (and its media lackey), are covering up the real cause of the crash of TWA 800 (probably because the truth would be highly damaging to the American government itself).

    Catastrophic failure
     

    One expert told USA TODAY the lack of warnings about a problem aboard the aircraft suggests a catastrophic failure. Steve Marks, a partner at Podhurst Orseck law firm in Miami who has represented relatives of victims in airline crashes, said the Boeing 777 should have been relaying reports of problems — if there were any. A lack of reports could mean a catastrophic failure, perhaps from the plane breaking up.
     

    Mechanical failure
     

    The plane's transponder, which identifies it to civilian radar systems and other nearby planes, was not working. Experts say a massive failure knocking out its electrical systems, while unlikely, could also explain the outage.
     

    Pilot sabotage
     

    Another possibility on why the transponder was not working is that the pilot, or a passenger, likely one with some technical knowledge, switched them off in the hope of flying undetected.
     

    Pilot error
     

    Officials haven't ruled out pilot error, though information provided by Malaysia Airlines shows the crew in the cockpit were very experienced: The flight was piloted by Capt. Zaharie Ahmad Shah, 53, of Malaysia. He has 18,365 flying hours and joined the airlines in 1981. The first officer is listed as Fariq Abdul Hamid, 27, of Malaysia. He joined the airline in 2007 and has 2,763 total flight hours.
     

    Terrorism
     

    U.S. officials told USA TODAY over the weekend they were reviewing possible terror links. Terrorism theories were fueled by information that two Iranians who boarded the flight had stolen passports. Interpol Secretary-General Ronald Noble said neither man has a criminal record. The two had bought tickets to get to Europe, where they hoped to obtain asylum.
     

    The plane kept flying
     

    A U.S. official who spoke to the Associated Press on the condition of anonymity said Thursday investigators are beginning to explore whether the plane may have flown for another four hours after contact was lost, based on the estimated fuel onboard and the inability of searchers to find wreckage.

    A fundamental aspect of radar operation is that the signal strength diminishes as range^4, due to spherical propagation of both transmitted and reflected wave fronts. Transponders essentially amplify and retransmit the signal (often adding additional information), so the effective attenuation is only proportional to range^2. This makes a very big difference to the maximum tracking range for a given radar system. So, switching off the transponder could easily make the plane disappear from ATC's point of view, with the reflected signal from the aircraft skin being well below the noise floor.

    Military radars are designed with uncooperative targets in mind and tend to be much more powerful. Long range early warning radars have typical ranges of a few hundred km, which can still leave a lot of gaps on a regional/global scale.
