You heard you can now use your iPad during all phases of the flight, right? Well don’t get too excited:
Can I use my e-book reader/tablet/cell phone throughout my flight now?
Once your airline has shown the FAA its airplanes can safely handle radio interference from portable electronics, they can let you use your devices in airplane mode only most of the time. At certain times — for example, a landing in reduced visibility — the Captain may tell passengers to turn off their devices to make absolutely sure they don’t interfere with onboard communications and navigation equipment.
So the FAA has approved it, but now the airlines themselves have to send data to the FAA to allow passengers to use these devices. That shouldn’t take any time.
