"No mobile" signs are to replace the outdated "no smoking" signs above airline seats with the introduction of in-flight mobile phone services in Europe next year.
Air France will be the first airline to trial the satellite-based technology early next year, followed by the UK's BMI and Portugal's TAP.
The technology, developed by Airbus and Sita joint venture OnAir, will allow passengers to make in-flight mobile calls and send text messages on short-haul flights across Europe at a cost of around $2.50 per minute.
The overhead "no mobile" signs will be retrofitted to old aircraft and fitted to new Airbus planes coming off the production line, which will be used by airlines to provide the in-flight mobile phone service.
The illuminated "no smoking" signs have now become outdated since almost universal bans on lighting up on scheduled passenger planes were introduced in the late 1990s.
The "no mobile" sign will show a mobile phone crossed out and will be illuminated during take-off until the plane has reached a certain height in order to ensure there is no interference with mobile networks on the ground.
A spokesman for OnAir told ZDNet UK sister site, silicon.com: "After take-off, an announcement will be made that passengers are allowed to use their mobile phones. At this point the 'no mobile' sign will be turned off."
The new signs are currently only applicable to Airbus aircraft but OnAir said it hopes to have them on Boeing planes as well if the in-flight mobile service is extended to its aircraft in the future.
Boeing last month warned the financial markets it may take a $315m hit on the sale or closure of its own troubled in-flight broadband technology operation Connexion, which has struggled to take off.
Talkback
What next? No s*x signs replacing no mobiles signs? If a high proportion of the world's people enjoy something, it is sure to get banned. Even with "No Mobiles" signs, it's a guarantee that many businessmen, especially those in economy class, will ignore the signs unless they are caught red-handed by a Stewardess. Let's have smoking, mobile phones, unlimited dope, loads of loud music and a large extension to the Mile High Club for all long haul flights. Otherwise, we can all become boring old farts and sit quietly, watching clouds go by, for 10 hours.
please god no, it is bad enough listening to stupid calls at high volume while waiting to take off. Now to have them also while in the air is unthinkable
