Digital Photography On Aircraft Not Permitted on Take Off orLanding
Podge wrote:
I was on an Air New Zealand flight a while ago, and I started to take a few pics (from my digital still camera) as the aircraft took off. An air hostess politely told me that the use of electronic devices was not permitted during take-offs or landings. I told her that I was using a dedicated still digital camera and not a camcorder, but she still asked me to turn it off. About 10 minutes later, when land was well out of sight, we were able to turn on our "electronic devices". But about 10 minutes before landing, while still over the sea, all electronic devices had to be turned off again. The only worthwhile photography from this flight was during the first and last 5 minutes of the flight, and this would apply to many other flights that I have been on. Now I know that the use of camcorders has been banned during take-offs and landings, but I didn't know that digital still cameras now suffered this fate. My digital camera can't take movies, but I know that a lot of digital still cameras can also take movies. From a practical point of view, does anyone know whether digital cameras really CAN interfere with an aircraft's navigation systems? Are airlines being a little too cautious with regard to the use of digital cameras and camcorders? About 5 years ago, nobody cared when I used my camcorder or digital still camera during take-offs or landings, and there were no reports then of interference with the aircrafts' navigation systems! So what has changed during the last 5 years? One time on a flight I had my mobile in the overhead thingie and my BT headset and PDA on me. Heard a vague vibrating noise from above about 10 mins into the flight and the BT headset beeped... Oops... Then figured I would try getting on the net thru the phone and that worked a bit for a few mins till it got higher. And then my mate was poking thru someone elses windows shares on their laptop that was broadcasting an adhoc network. Both didnt result in a crash. |

So I did. The plane didn't crash and burn. I asked if I could use a GPS during a flight recently and was told that I could. I think asking is the key. David Gosh, you guys must be better looking than me (or something) because I was told that using my GPS on a flight was an absolute no no! I doubt whether any airline's official policy would allow the use of a GPS in flight because it is transmitting quite a powerful RF signal to satellites above. no it isnt. gps's are receivers. the satellites are the transmitters. the gps doesnt transmit anything. if my mobile is left on in my pocket when I go flying I can hear quite loud bdip bdip bdip bdip noises through my aircraft radio as the mobile synchronises with the cell. I'd hate to be flying with 50 of the buggers up the back. Stealth( cachophony comes to mind ) Pilot |

wrote: A good web site, thanks. I can't imagine that tiny digital cameras would pose a serious threat to an aircraft's navigational systems, so I would like to see some serious research that proves that they do. I don't doubt that some such devices could generate interference... but I would seriously hope that systems so critical as those on a modern airplane would be a bit more hardened against such low-level interference. One can only imagine the sort of havoc that could be wrought if someone was actually TRYING to screw up the avionics! ahhhh 'scuse me miss. are we at 10,000ft yet? I wanna run me tesla coil for a bit. Stealth Pilot |

From what I have read so far, there seems to be more of a problem with equipment that has radio transmitting and receiving abilities. I very much doubt that a digital camera could cause interference on the same scale as a cell phone, for example. But, perhaps the answer is to revive my old film camera and use this on flights instead of a modern digital camera? Fifty fifty as to which is worse. The cell phone has a higher output level, but it produces radiation within a relatively narrow band of frequencies. The camera is little different than a laptop computer, and while it produces only very low levels, the frequency range is very broad. -- Floyd L.

The argument that some electronic device will interfere with the plane's navigation is bull****--and, if it were true, then it would make sense to ban the electronic devices while cruising, when they could get lost, not on takeoff and landing when they can see where they are going. Any airplane that could crash because some 10 year old kid is playing his PS2 is a plane I wouldn't want to fly on, and neither would you. Don't fly on any airplanes then, because potentially they *all* could. The difference is that at altitude very few problems are critical. The pilots have time to determine that an instrument is not accurate, and can make reasoned decisions about alternate methods to compensate. During takeoff and landings, they are making split second decisions one after the other and the effect of an instrument failure is magnified many times. I doubt that there has been a single plane in the last 10 years that hasn't had at least one person leave their cell phone on for the entire flight, and there have been none, zero, zip, zilch, nada crashes therefrom. But there *have* been instances of interference with the flight instruments from cell phones. The reason there have been no crashes is because they are banned, and the exposure has therefore been reduced. The goal of all of this is to turn the passengers into sheep. It sure looks like the plan is working. Nobody cares that you are woolly. -- Floyd L. Davidson http://www.apaflo.com/floyd_davidson Ukpeagvik (Barrow, Alaska) |

Although a digital camera may have some components that are also used by a cell phone, a digital camera can't transmit a powerful radio signal like a cell phone can. I would regard a transmitting cell phone as a much higher risk to navigation equipment in an aircraft than a switched on digital The cell phone does not generate a wideband radio noise virtually across the entire useful frequency spectrum either, and your digital camera does. camera, because of the cell phone's ability to transmit and receive radio Receiving radio signals is not a risk factor. signals. I think Air New Zealand would also agree with this viewpoint as there are quite stringent rules with regard to the use of mobile phones: http://www.airnewzealand.co.nz/trave...#priorapproval What they say about mobile phones has virtually nothing to do with how digital cameras present a risk. "Mobile phone use is permitted on all Air New Zealand aircraft when the aircraft is stationary on the ground, with the entry door(s) open. When the last entry door is closed, you will be advised to switch off your mobile phone/PDA. Please leave it off until you are advised that you are permitted to turn it back on again in-flight, should it be equipped with a flight or safe mode. Flight or safe mode mobile phones and PDAs may be used in-flight. Flight mode enables the basic functions of your mobile phone or PDA to be used whilst disabling the transmitting function. To take advantage of this, you must switch your device to flight mode, and then turn your device off, before the aircraft doors are closed. When the device is turned back on again, it will already be set to flight or safe mode and deemed safe. At no point during the flight will you be permitted to make or receive phone calls or SMS texts, send or receive emails, or use the internet." That suggests they would not agree with you at all! -- Floyd L. Davidson http://www.apaflo.com/floyd_davidson Ukpeagvik (Barrow, Alaska) |

It will be amusing to see the reverse when mobile phones start being allowed on suitably equipped flights! Cell phone systems are not compatible with aircraft operation. Can you imagine, for example, how many cell sites will be triggered if you are at 35,000 feet over London and try to get a dialtone? -- Floyd L.
