Am I the only one who finds it odd that many people seem to think that it's unreasonable to expect people to know the difference between turning a device off and putting it to sleep, yet at the same time they feel that these same people should be allowed to exercise their own judgement in terms of the level of risk involved in leaving it on?

As an engineer who flies every month. When they ask for electronics to be turned off, I mark my page and close the cover. I have a Sony, so there is no pesky radio and I know the eink is not held in place by electric signals.
However, I never point any of this out to the flight attendants. I value my safety, and as a result I do not want any flight attendants thinking or analyzing electronic designs. They are simply not qualified. Just like they don't know my watch is powered by an electric motor. The engineering reasons are not the point. They need simple rules, and they need it to look like you are following them. Some electronics are bad, and problems have the most significance near to the ground. We have a rule to mitigate that risk. The rule can't be "only bad devices must be turned off", because then we'd need someone to test devices, and the airlines would need a 500 page list. That's a bad rule. The current rule is much better. Please turn off your toys, quickly, so you don't make my plane late. |

This is what I posted the last time this topic came up...
The FAA takes air safety VERY seriously (which is a good thing). You would not believe the amount of testing that is required to certify a new piece of electronic gear to be installed on an airplane, and this is stuff coming from companies that are specifically designing electronics for flight operations. The FAA's main point of view is that if it has not been thoroughly tested and certified, then they don't want to take the risk. If they don't KNOW that a device is safe, then they say that you have to turn it off. If you look at it case by case, are there some devices where it seems silly to require them being turned off... sure. But the general policy from the FAA is, for the most part, a good one. If they're not positive it's safe, then the answer is no. The only way they are positive is if it goes through their certification. No company selling consumer electronics (cell phones, ebook readers, etc) that are not specifically being designed/sold for flight operations is going to want to spend the amount of time and especially money it would take to get it certified by the FAA. Such use would only be a tiny part of their market anyway. |

The DR800 can't be turned off. You're only required to turn off devices that can be turned off. But when a device can be turned off, you are required to do so. It's not optional; I'm pretty sure that it's a legal requirement.

You're normally pretty hot on legal issues, Shaggy. You tell me; what does the law require? |

Says not to operate it. Which putting it in sleep mode satisfies. How does that petard feel? |

The section you quoted doesn't say anything about completely shutting down all activity for takeoff and landing. If the device complies with (b)(5) and doesn't interfere with the aircraft, then it doesn't interfere. The rule you're quoting doesn't make a distinction between above and below 10,000 feet. Maybe some other rule does, but this one doesn't.

It it's not switched off, then it must be switched on, and hence is "operating".
Shaggy, if I read this correctly, it appears to say, relating to your question about the DR800, that unless "the operator of the aircraft has determined [that it] will not cause interference with the navigation or communication system of the aircraft on which it is to be used." then you are probably committing a Federal crime in taking it onto the aircraft in the first place? |

I've always rather assumed that the reason for the complete ban on takeoff and landing is so you'll be alert and listening to the instructions of the cabin crew in case of emergency. Evacuations happen at takeoff and landing, not at 30,000 feet.
