Qantas Looking To Blame A330's Sudden Drop in Altitude On Passengers' Gadgets?
Posted by John Mahoney at 3:45 AM on October 10, 2008
Earlier this week, a Qantas A330 inexplicably climbing 300 feet then nose-diving back down. In the cabin, 71 people were injured. Interestingly, the ATSB is now looking at in-cabin interference from personal electronics as a possible cause of the "irregularity with the aircraft's elevator control system." Wait, what? Really?
AU: I feel the need to clarify this: the original article on this stated that investigators were looking at "onboard computers" being the cause of the sudden dive. An enterprising (and unnamed) journo at AAP decided that "onboard computers" must mean "passenger laptops" and hence the rumour was born. While the investigators havent ruled out passenger laptops as a possible cause, they also haven't ruled out the possibility that the co-pilot rendered the entire cockpit unconscious with a stench-laden, in-flight meal-fuelled fart (okay, they may have ruled that out). My point is that this is a media beatup fuelled by some shoddy journalism. You may continue flying with your gadgets without fear of dying.UPDATE: Check out this APC piece by David Braue about the whole incident. It's a good look at the real facts involved with the story.
This wouldn't be the first time Qantas has blamed passengers' gadgets for an in-flight mishap; in July, a Bluetooth mouse was said to have resulted in a Qantas jet's autopilot being thrown off course. Passengers on Tuesday's ill-fated altitude drop will now be questioned regarding what electronics they may have been using at the time of the incident.
The issue of whether everyday personal electronics can actually cause any significant problems on board an airliner is clouded, to say the least. On one hand, it's hard to see how such common devices that meet FCC and UL interference standards can affect airliners that are designed to be able to withstand lightning strikes--critical components on a commercial jet are shielded to prevent any kind of interference getting through. On the other side, claims of the insulation degrading in older jets making them more susceptible to interference make sense. Then of course there is the perfectly rational "why chance it" argument.
This Wiki page delves into the issue in more detail, and Patrick from Ask the Pilot, one of my favourite online columns, gave the issue a characteristically sober and level-headed look earlier this year (verdict: interference technically possible but highly unlikely). So why Qantas would be making a push for this line of reasoning is kind of a mystery.
What about you guys? Do you heed the warnings to turn off everything, or fly in the face of danger with iPod blaring away during takeoff. Must admit I've been guilty of the latter, occasionally.

I was an aircraft mechanic my first four years in the Air Force. One thing that I learned is that our electronics DO NOT cause interference with any of the avionics. The FCC pretty much controls at what frequency everything can transmit and you would need a defective piece of equipment in order to cause such interference, and it would be minor.
Can it happen? Sure, but the probability is slim to none, and slim is out of town.

You know, I have to wonder how spoiled we are that we can't bear to not use our personal gadgets for the 15-20 minutes at both ends of the flight that the cabin crew politely asks us to keep them turned off.
I'm also for never, ever allowing cell phone conversations on planes.

Sorry 'bout that. It was me. I was listening to Cool the Engines by Boston and the damn plane started shutting down. Thinking quickly I switched to The Steve Miller Band and Jet Airliner.

I call bullshit. Qantas, after a reasonbly unblemished safety record (and they've never lost an aircraft), have come under some scrutiny lately after several maintenance-related issues (bits falling off, doors blowing out).
They are just trying to divert attention away from what is probably yet another maintenance issue.

[quote]On the other side, claims of the insulation degrading in older jets making them more susceptible to interference make sense.[/quote]
This is in reference to electrical insulation that is being degraded (as in the plastic is becoming less flexible and breaking off), which has nothing to do with the capability of those wires to block electro-magnetic interference (EMI). If the EMI shielding was going to pot we'd have the planes falling out of the sky every time they flew within 100 miles of a radio tower, cell tower, CB radio, etc.

I do lightning testing at a major avionics manufacturer (Boeing, Airbus, Cessna are our big customers) and these items are capeable of causing interference on an airplane.

If you want to put a tinfoil hat on, it looks like someone in government was covering up for an Airbus deficiency to keep the company's reputation in good standing world-wide.
However even the engines for these planes were modified after the fact. The pilot of the flight did jail time for manslaughter.

@ford4life: Air France flight 296 at an air show... The voice-over is sort of misleading... This is an Airbus 320 w/ Fly-by-wire. Basically, the computer attempts to prevent the pilot from doing things that would overstress the airframe.
There was a VERY large scandal over this crash, including switched flight recorders.
The plane design had engine acceleration issues that Airbus had posted a notice about, but Air France had apparently neglected to pass the info on to pilots.
The pilot was supposed to fly no lower than 100'...

Why would any of you assume that every electronics you carry would be safe on any flights. Oh sure, FCC prevents frequency overlapping, but that compliancy is only for US devices. When you're dealing with international flights or have international passengers, you can't guarantee all devices are FCC compliant. That is why the FAA rule is there regardless of the safety from FCC.

There seems to be some confusion about the rules regarding the use of portable devices on airplanes.
Here are the reasons you need to keep everything turned off in the first/last 10 minutes:
1. Turn them off so that you are not distracted from the crew's instructions in case of trouble.
2. In case of a mishap (which is most likely to occur at takeoff or landing), your devices can become projectiles, which is why you need to have them stowed in the overhead bin or under the seat.
You are allowed to use these devices while the plane is cruising at altitude.
You are not allowed to use RADIO devices at all, as they can cause interference with the navigation systems (ground-to-air transponders, etc.). All of you who think you know better than the crew, please just stay off the planes. (By the way, the expensive, in-seat phones and all the other radio devices on the plane use frequencies that are known NOT to cause interference... It is not the same as your cellphone or radio controlled car.)

Come-on folks, can't you want that extra 5 minutes??? Whatever you think you need to say can wait, I promise.
I was originally a bit skeptical of all the concern (though I still turned things off) until about 5 or 6 years ago while checking-in to a Southwest flight of Burbank Blvd. I had placed my StarTac phone on the counter while getting my boarding pass but the attendent's computer screen went blank or froze or was otherwise out-of-commission. I removed my phone and all was well. Just one datapoint, to be sure, but it convinced me.

As an air traffic controller, I am around aircraft and piles of electronics every day. Years and years of this and not a single issue. We have all sorts of interfering radio signals flying through the air including cell phones. It's crap. How many cars die each year on the highway because someone's cell phone shut them down? I am all for people never being allowed to talk on their phones on planes just for the annoyance factor but seriously, a bluetooth mouse causing an airliner to nosedive? Have they checked to see if there was an SBX tracking radar nearby in the water? A floating radar the size of an oil rig is much more likely to have confused the computer.

The only reason I can think of that everyone is asked to keep electronics shut off during take-off and landing is so that they don't distract the pilots with loud, unusual noises.

@Lite: The problem with the fly by wire in that accident was the airplane thought it was in a different phase of fligt (landing) than the pilot did (go around), and the airplane did not respond to his inputs the way he expected. It was a flawed understanding of the software on the part of the pilot in command.

He forgot to turn his off on a flight, and when they dialed up the localizer course (final approach), he received a phone call at the same moment and the course indicator swung to the opposite side. It stayed there until he turned off his phone, then returned to normal.

Yeah, Yeah, gadgets are waaaayyyyy too dangerous to be used at takeoff or landing, but they are perfectly safe at 37,000 feet.....Does anyone else see how ridiculous that is? If personal devices were thought to cause a massive safety problem on flights, do you really think they would even allow them on the plane? I doubt that they would take the chance of letting stupid, or devious, passengers take them onboard.
That's like saying "ok, you can take your sidearm on the plane if you promise that you didn't bring the bullets with you...no, no... no need to prove it, I'll just take your word for it. Welcome aboard."
If there was proof or some verifiable incident, we'd be getting onboard with nothing but a newspaper. All carry-ons would be stowed in the hold in a shielded cargo box and you would be patted-down for gadgets.

I've been flying Airbus fly by wire aircraft for 17 years. I was somewhat sceptical about electronic interference until I had an incident and that was enough to convice me. I had just commenced descent when both of the navigation displays failed simultainously. Shortly after that, the Purser reported that a passenger was using a mobile phone in the first class cabin and refused to turn it off. He was seated directly above the avionics compartment. The passenger was again instructed to turn his phone off, and this time he complied. Shortly after, both nav displays returned to normal. That occurred early on in my 'electronic aircraft' experience and was only the one time, but that was enough to convince me. I've also been struck by lightning in an airbus, right where the avionics compartment is. No problem with any of the aircraft systems, just some burn marks along the fuselarge. Transmitting devices should never be used by passengers on board aircraft, fullstop. It is, however, deemed extremely unlikely that non transmitting electronic gadgets can cause interference, and that's why they are allowed to be used, but at cruise altitude only. If there's a chance, however slight, of a ghost getting inside the machine, at least then the crew would have time (height) to recover. Imagine the consequences of the Qantas incident if it had occured during takeoff or on approach. For those even more in the dark......... Queensland And Northern Territory Aerial Services is where the QANTAS name is derived from.
