737 aircraft & flight mode on iphone
Just got back from Prague flying back with BMI Baby on a 737 500 seires and was told that flight mode in mobile phones was not allowed on this type of aircraft. I have an iPhone and wanted to listen some tunes like I normally do when fly with Virgin or BA. What's so different with the aircraft?
Unfortunately, it's another of those "grey" areas - like security procedures. Some airlines will allow flight safe mode, some not. In the USA, Russia and some European countries, mobile phones may be used after touchdown. This causes considerable problems when those passengers fly on British airlines where this is normally not the case.
But there you are, that's commercial flying and rules is rules.
You have to grin and bear it

No quite as simple as that, since national aviation authorities often dictate to airlines.
But given the (understandable) reluctance of the industry to play fast and loose with safety related matters, conservatism usually drives the rules.
The CAA in Britain has recently modified its stance regarding the potential use of mobile phones and here is the info

I have a PPL and have seen the effect that a GSM phone can have on nav equipment. Whilst pax do inadvertently leave their phones on in flight, without any apparent problem, I second the cautious approach!

That link refers to the use of mobile phones. The OP is not suggesting use of a mobile phone. They are asking why the PED element cannot be used in Flight Safe mode on BMI. A reasonable question given that VS, BA and quite a few others do allow use. Therefore, the suggestion it is a company decision is probably correct.

Yet many airlines which will not allow the use of "flight mode" on a telephone will allow use of laptops, all of which nowadays have wireless capability.
The rules at the above reference specifically exclude the use of virtually all modern laptops as they all contain wireless network devices.
I have often seen passengers challenged by cabin crew if they are using a telephone. Never once have I seen a laptop user questioned.
"Excuse me sir , does your laptop have a wireless device built in?"

Does WiFi in a laptop use the same frequency as a typical mobile phone ? Further, does a laptop which keeps searching for some local wireless network have the same effect on navigational kit ? What about laptops with Bluetooth installed ?

Wifi is around 2.4GHz along with microwave ovens. Cellphones are very approximately 800-950 MHz and 1.8-1.95GHz, depending on the technology used.

Just pointing out that using mobile phones on aircraft is not an airline only decision and showing how the CAA has changed it's view.
Flight mode or otherwise, it's still a mobile phone, although the CAA view seems pragmatic and does not scope flight mode into the rules.

WRT laptops, I found out recently that Air Malta now allows the use of DVD drives in flight.
Apparently their rules changed a while ago.
Optical drives used to be a no-no in flight, anyone had experience with other airlines?
Regarding wifi, I always make sure that my laptop wifi is physically switched off before boarding (unless using it with the now departed Boeing Connections service) and I tend to choose laptop models with a physical, rather than software, switch.
I always switch off my BlackBerry, as I don't trust the 'soft' switch to disable the radio.

Interesting question and no I haven't. If they asked me, I'd show them that it is switched off (there is an external switch) and thus is a non transmitting PED.
I did once see someone challenged for using a built in CD drive - that was years ago, though.

Bushfiva is on the money regarding frequencies (Bluetooth also uses the 'microwave oven' 2.4GHz band). The signal power is significantly different, however:
Mobile phones - maximum of 1-2W
Wi-fi - maximum of 100-200mW
Bluetooth - maximum of 1-2mW
Mobile phones - maximum of 1-2W
Wi-fi - maximum of 100-200mW
Bluetooth - maximum of 1-2mW
