I was wondering why you cant have your cell phone on in an airplane?? My phone has a setting called airplane mode, would that be okay to have on while the plane is moving??
Nowdays, on up to date passenger aircraft, it is fine to turn it on once the seat belt lights turn off, there is even an onboard cell tower because the ground ones wont work inside an aircraft. Make sure it is ok before you turn it on! Because this is only on up to date aircraft and there are still commercial passenger aircraft in the sky that are 30 or even 40 years old and on these it causes problems.
You cant have your cell phone on when on an airplane becuase its signals block out the signals from the air plane towers going to the air plane. Even with airplane mode setting, it still does it. Thats why you cant have it on.
it might interfere with certain flight systems
