Well if Flight Mode shuts down both bluetooth and the phone dialer itself, so that the phone can not transmit radio signals... then why would it interfere with devices on board???... hell an electric razor probably would cause more interference!!! damn facist bastards!!! | |

This whole thing about not to use mobile phones i aircraft is a hoax. In the early nineties Ericsson and SAS made an extensive study with elaborate field tests and found absolutely no interference with onboard instruments. At the same time SAS had started to roll out onboard creditcard phones in their aircraft so the report was classified since obviously they wanted as much traffic as possible from the creditcard phones (at ridicously high prices). So stop worrying that your phone might interfer with the plane.

Here is the UK Civil Aviation Authority (CAA) ruling on this subject and here is their research summary page on the topic.
Vodafone participated in a test withe CAA earlier this year and the conclusion was that mobile phones should still be banned.
the following was taken from this PCWorld article which also mentions that SAS specifically allow the use of phones equipped with flight mode such as Nokia 9210i and  P800
.....
Airlines should continue their ban on the use of mobile phones on board aircraft because of possible interference with navigation and communication equipment, according to a study published Friday by the U.K. Civil Aviation Authority.
A series of tests exposing a set of aircraft avionic systems to simulated cell phone transmissions revealed various adverse effects on the equipment's performance, CAA said in a statement. Although the equipment allowed a margin above the "original certification criteria for interference susceptibility," the margin wasn't sufficient to protect against potential cell phone interference under worst-case conditions, the authority said.
Vodafone Group participated in the tests.
Suffering a Setback
The study could deal a blow to some airlines, such as Scandinavian Airlines System, which hope some day to offer passengers the opportunity to use their mobile phones in the air in much the same way they're accustomed to on the ground.
Cell phone use has long been banned on airplanes, while the use of many other electrical devices such as notebook computers is banned on take-off and final approach. But passengers, particularly businesspeople, are interested in using their phones on planes to keep in touch with their offices and customers.
In the U.S., the Federal Aviation Administration bans the use of cell phones on airplanes because, like the CAA, it too is concerned about wireless calls interfering with a plane's navigation system.
Safety Concerns
From March 1996 to December 2002, CAA recorded 35 aircraft safety-related incidents that were linked to cell phones, the authority said.
The reported interference incidents included interrupted communications due to noise in the flight crew's headphones, according to the study.
CAA recommends a continued ban on mobile phone use by passengers in aircraft and urges airlines to introduce safety procedures that ensure phones are switched off.
Whether the CAA study will encourage airlines to prohibit the use of mobile phones with flight-safe features remains to be seen.
Flight-Safe Mode
Last week, SAS announced a policy for allowing passengers during flights to use all mobile phone functions, such as calendars, address books, and reading e-mail, that require no signal transmission. To do so, passengers require phones equipped with a flight-safe mode, which essentially prevents a handset from sending or receiving signals required to make phone calls.
Nokia with its 9210i Communicator and Sony Ericsson Mobile Communications with its P800 smart phone are among the first manufacturers to offer handsets with the flight-safe feature.
"We continue to recommend to our customers that they should turn off their mobile phones when inside aircraft and should only turn them back on if equipped with the flight-safe mode," said Nokia spokesperson Damian Stathonikos. "But we understand that some airlines prefer passengers not to use their mobile phones at all."

The airlines are well aware that there is only an extremely small risk of problems with using phones, same as the ban on mobile use in roadside filling stations, but at the end of the day, its THEIR rule & they can tell you to wear a clown outfit while flying with them if they want, it's up to you if you want to use the service you must do it on their terms.
Maybe that guy in the Macdonalds ads comes over by sea, ...i don't know.

My Siemens SL45 had flight-mode and I bought that nearly three years ago! |

Although I do find it very inconvenient not to be able to use my P900 (or P800 as the case once was) on a flight I don't think that its the end of the world. I use my P900 for busniness mostly and really time spent in an airplane could be spent more productively than drinking the free champagne and eating the free food, I just can't stand all that time wasting:) The worst part is that they have started to include massages in-flight too! Give me spreadsheets, documents that need read and speeches to prepare any day of the week

that incident happened to me also when i travelled to bangkok using lufthanza. they asked me to turn off my fone, even though i showed them that it's on a flight mode.
since that i don't want to cause any arguments and be the cause of the delay, i had no choice but to turn it off. |

I understand airlines policy, but it's always boring when flight-crew ask me to switch off my pda and my walkman during take off/landing. Come on, It's non-communicate device :-(

Is it called 'flight' mode for the very reason that you can use it during a FLIGHT, or for some other reason? |

For some other reason.

I can't get a signal in town, so there ain't a hope in hell 35,000ft up!
The following is taken from,
"P900/P908 White Paper, October 2003, Sony Ericsson, Page 73 -74"
Interesting sections to this post are from, 'Certification' onward, but I included the rest beacuse I couldn't be botherd cutting it.
Flight Mode
What is Flight Mode?
GSM or Bluetooth radio signals from a mobile phone may be harmful to the safe operation of an aircraft.
Flight mode is a special mode of the P900/P908 in which the phone does not transmit such signals, but
allows the user to read and write information resident in the PDA part of the device.
How it works
1) Ordering the phone into or out of Flight Mode can be done in two different ways:
• From the Power Button
• From the Status bar signal strength icon
2) When going into Flight Mode
• The radio signal strength indicator, RSSI changes into a red circular Stop Symbol
• The radio transmitters for both GSM and Bluetooth are switched off
• The operator name is changed into "Flight Mode"
3) While in Flight Mode:
• The phone does not emit any intended radio signals
• Unintentional signals caused by the electronics in the phone are at a similar level to other consumer
electronic devices and do not exceed levels stated in FCC part 15, or EN550022.
• The phone can not by itself leave the Flight Mode.
4) When leaving the Flight Mode:
• The red circular Stop Symbol once again changes into the normal radio signal strength indicator, RSSI
• The radio transmitters for both GSM and Bluetooth are switched on
• The text "Flight Mode" is changed into an operator name
Certification
The above facts are hereby stated and certified by us, the manufacturer, Sony Ericsson Mobile
Communications AB, located in Stockholm, Sweden. There is no certificate from any independent
certification authority.
Flight attendants
It is important that flight attendants learn how to recognize:
• What phones is Flight Mode capable
• That the phone is in the Flight Mode stage
We recommend that no devices be switched on during take-off and landing.
Regulatory
Currently, the FAA has issued a document, USE OF PORTABLE ELECTRONIC DEVICES ABOARD
AIRCRAFT, stipulating how airlines should handle these devices.
The document is due for a make-over, probably by the end of 2003.
The EUROCAE (European Organization for Civil Aviation Equipment) released a document WG-58 (Working
Group-58) that outlines tests and PED evaluation aboard European aircraft.
Standardization
It is the opinion of Sony Ericsson, that:
• Flight Mode ought to be standardized. Suitable bodies for this may be the FAA, IATA etc. Both the user
interface and the procedures should be standardized.
• No new radio emission standards need to be set up for Flight Mode. Instead, existing standards should
be applied; e. g. FCC part 15, or ETSI EN550022.
