Hi all,

Had a first today with an unexpected twist I wanted to ask the the community here about.

Landing into Linate this evening we were on a full autoland due to low-level fog and as SOP were asked to switch all electronic devices fully off (not flight-safe mode). As the cabin was prepared for landing I got up to turn off my iPad which was in the overhead however a member of the cabin crew said that it wasn’t necessary as long as the device “didn’t emit any light” (which it wouldn’t stored in my bag). I always thought that the reason devices needed to be off was to ensure no radio waves were emitted causing interference with the CAT III ILS signal - is this not the real reason? Surely my iPad in “standby” in the overhead would emit radio waves even with the screen off (for example Bluetooth can remain on even while in Airplane Mode). Was the cabin crew wrong and should I have turned off the iPad fully?

Looking forward to hearing from the experts in the community here.

Thanks,
TUF
