Those weigh more than Kindle, for example.
BTW, how hard would it be for FAA (or airlines) to say exact iPAD model AA is using (probably iPAD 2 wifi 16G version?) and say only that model is approved for use?
I don't understand why portable voice recorder or electric shaver
(that hasn't been tested at all) can be used but not the thoroughly tested iPADs.
Shavers emit harmonics of the fundamental frequency and its harmonics. None of these frequencies are anywhere near the RF range. It's even below AM. Moreover, shavers are not designed for the purpose of transmitting electromagnetic waves. Any emission by a shaver is a consequence of rotation of its motor. Voice recorders also are not in the business of communicating via electromagnetic waves.
iPad in the cockpit are under direct control of the cockpit crew. Their use has limitations, such as only read only connection with data systems, and transmit/receive ability for AAC only. PAssengers are not allowed to do everything pilots needs to do.
