Boeing Told To Replace Cockpit Screens Affected By Wi-Fi

Rambo Tribble writes The Federal Aviation Administration has ordered Boeing to replace Honeywell-built cockpit screens that could be affected by wi-fi transmissions. Additionally, the FAA has expressed concerns that other frequencies, such as used by air surveillance and weather radar, could disrupt the displays. The systems involved report airspeed, altitude, heading and pitch and roll to the crew, and the agency stated that a failure could cause a crash. Meanwhile, the order is said to affect over 1,300 aircraft, and some airlines are balking, since the problem has never been seen in operation, that the order presents "a high, and unnecessary, financial burden on operators".

      The FAA realizes that regardless of how many times the crew tell passengers to turn off their RF emitting devices people are still going to ignore them or not even realize the device is on in the first place.

      Typically the primary displays in the cockpit all have the same part number - just different configurations/strapping. This keeps the quantity of replacement screens on hand down.

      The pilot and copilot sides are (mostly) isolated from one another. Power is provided via two separate busses and redundant subsystems feed the respective pilot side. In this case however all of the screens have the potential to fail at the same time regardless of these redundancies. This is obviously BAD. This is why the FAA is particularly antsy about this issue.

      Of course there is always a backup set of instruments in the cockpit... but the intention is to maintain the primary systems and eliminate any potential for failure.

      Might interest you: with speakers, it only interferes if you're inducing it into a pre-amplified line (where the signal levels of the wifi and the regular audio line are comparable and amplified together). Once past that, the audio signal is so strong that any induced wifi noise is essentially imperceptible. For example, a rather powerful antenna signal is about -40 dBmW, whereas audio amp output power level is approximately +40dBmW (for a ~10W speaker). That's a good 80 dB of delta, or about the difference between a whisper in a really, really quiet room at 6 feet (30 dB) and a jet at takeoff (110 dB).

      Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes, and
      Model 777 airplanes. This AD was prompted by testing reports on certain Honeywell

      to radio frequency emissions in WiFi
      frequency bands at radiated power levels below the levels that the
      displays are required to tolerate for certification of WiFi system installations.

      Clarification of Cause of Unsafe Condition
      The cause of the unsafe condition stated in the Discussion section of this AD is a
      known susceptibility of the Phase 3 DUs to RF transmissions inside and outside of the
      airplane. This susceptibility has been verified to exist in a range of RF spectrum (mobile
      satellite communications, cell phones, air surveillance and

      radiated power source (set-up in the flight deck) was increased to a high level. VOZ also
      stated that under normal operating conditions of the WiFi radiated power, there was no
      blanking of the DU, but interference was present only at a certain frequency. [...]

      [...]

      The susceptibility of phase 3 DUs to RF transmissions was initially identified
      during a WiFi STC installation by an operator and a WiFi vendor and reported to the
      FAA. As a result of this discovery, we performed a risk assessment for in-service
      airplanes equipped with phase 3 DUs using our established COS process, which
      determined that an AD action was warranted for this issue. In addition, Boeing did an
      independent safety review and also determined that the DU blanking was a safety issue

    Dear Airline,

    Please fix your cockpit system.

    We, the passengers, LOVE our WiFi gadgets so much that even our kids have WiFi enabled Fisher Price tablets. With the Internet of Things, practically everything has WiFi in it: cameras, phones, tablets, laptops, kids toys, kid tracking devices, etc. And if you think that every single one of these are turned off during the flight, you are fooling yourselves.

    Just because there have been no public reports that the system has been interfered with, doesn't mean that it hasn't happened or won't happen. It just means that you have been lucky so far. Take a page out of the car manufacturer's handbook. They had known issues that they didn't fix and look at all of the trouble that they have been in!!! This could be you, only 100x worse.

    So, do the right thing, stop complaining, fix your system, and let us get back to our margaritas...

    That's only cheaper if you think flight attendants work for free (and that they have the power to arrest anyone).

    They don't work for free but they do have the power to arrest. Not following the directions of the captain of an air vessel is a felony. Once the plane is moving by itself (even taxiing on the ground), the flight has started and the captain is the ultimate authority.

    So yes, the can, and if needed they will, arrest and restrain you if you interfere with the safety of the flight or fail to follow any legal directions. That includes telling you to turn off your phone.

    I think the smug bastards were those who refused to put away devices during takeoff, landing and taxiing on the ground. Their few minutes of delay being unacceptable.

    Smug bastards who dismissed pilot reports. Things like seeing a device interfere with navigation inflight. Literally taking the device to the cockpit, turning it off and seeing the deviation in heading stop, turning it back on and seeing the deviation in heading reappear, turning it off again and seeing the deviation stop again, etc.

    Smug bastards who fail to consider just how antiquated much of the **ground** control equipment used during taxiing is. And who fail to consider that some of the biggest air disasters that have occurred were the results of mistakes while taxiing. For example and aircraft moving across a runway when another is landing.

    Failure to replicate things in a lab is not proof that incidents do not occur. Guess what, equipment actually installed in aircraft is not always in pristine and properly installed lab conditions.

    "Boeing conducted a laboratory and airplane test with 16 cell phones typical of those carried by passengers, to determine the emission characteristics of these intentionally transmitting PEDs. The laboratory results indicated that the phones not only produce emissions at the operating frequency, but also produce other emissions that fall within airplane communication/navigation frequency bands (automatic direction finder, high frequency, very high frequency [VHF] omni range/locator, and VHF communications and instrument landing system [ILS]). Emissions at the operating frequency were as high as 60 dB over the airplane equipment emission limits, but the other emissions were generally within airplane equipment emission limits."

    Yes, you are right, but this is also true for any other non-law enforcement arrest. In this case, the captain's ultimate authority ends the moment the plane hits the gate and the flight has ended so he has to hand them over. Furthermore, a captain can delegate his ultimate authority to other flight crew, or even passengers should he deem that necessary. But as you could read in the other sources, a citizen's arrest is legally recognized in most of the world in cases of a felony. Interference with the flight crew also happens to be a felony in most countries as well. And remember, on a plane, the law of the country it is registered in applies as well.
