Are the children allowed to use gameboys on the plane?

LeCras said:I am obviously unable to comment on your particular flights, but most airlines prefer that entertainment devices are not used when the fasten seat belt signs are illuminated. This is to ensure your own safety - if they need to make a cabin PA announcement you are more likely to hear it without your headphones.![]()

disneyholic family said:i guess it must depend on the airline....on the airlines i've flown, they seem to have a 10,000 foot rule....when the plane reaches 10,000 feet after takeoff you're permitted to use electronic devices....and they always make an announcement that you're permitted to turn them on and when you have to turn them off before landing...
by the way, there are a few electronic devices that you're not supposed to use on planes at all, but i can't remember what they are....
but gameboys and ipods are ok...

Galactic Emperor said:Sorry,
but that's just´plain wrong. The main reason why electronic devices shall not be used during certain flight phases is the possible disturbance of the aircraft's navigational systems. As soon as you left the vicinity of the airport until you start the initial approach into your destination you can use electronic devices. The fasten seat belt sign during flight is more or less unnecessary anyway, as everybody should stay buckled up for the duration of the flight. A clear air turbulance can hit any aircraft at any time, only complete fools open their belts when the lights are extinguished after departure. The 'Fasten seat belt'-sign being switched on during flight has the meaning 'If you're walking around the plane or not in your seat right now, get back and stay seated!'.
And teh statement about the necessity to hear the PA is also wrong or the flight attendants would have to wake up every sleeping passenger in that case.
Galactic Emperor said:This one's wrong or least not completey correct: The position of the aircraft is not relayed to ATC via radio. This is done by RADAR. There are two different radar systems used for this.
Primary radar is used to 'see' the aircraft. This is doen by using those use rotating antennae which are shaped like a snow ploughs blade. The emitt a radar impulse which is reflected by the aircraft and displayed on a scope. Unfortunately this is just 'blip' not saying anything about the ID of the aircraft. For this there is
Secondary radar. This is a second system attached to the primiary radar's antenna. It's a long box usually located at the lower or upper edget of aforementioned 'snow plough'. This sends out a signal to every aircraft in its range. All aircraft have a so-called 'transponder', which then sends back a signal containing information about the ID and the altitude of the aircraft. This info is then used to generate a label on the Air Traffic Contoller's scope. Saying for example BA1234 410 480. This means British Aiways flight 1234 at Flight Level 410 (41.000ft) flying at 480 knots. The speed is determied by the radar sysstem's computer simply making a distance/time calculation between two sweeps of the scope.
The transponder in the cockpit can be set to 4096 different codes only as it is a 4digit code based on the oktal system. As there are more than 4096 aircraft on this planet, pilots have to change codes frequently when crossing airspace boundaries. Additiinally there are special codes available which can be set to attract ATC's attention, i.e. in case of a general emergency, unlawful interference (Hijacking), or radio communication failure.
