What are you referring to here?
- renewiltord 3y agoYeah I've often forgotten and left my ipad on cellular or my phone non-aircraft-moded. No one has ever said anything so it's unlikely they have automatic detection.
- lukan 3y agoIt also never happened to me, but I heard of stories, where the stewardess walked around with one. But they might have gotten less paranoid about it(since nothing ever happened?). Chances of bad interference are probably very low.

- ptero 3y agoI think (although not sure) that cell phone on planes ban was much less about interference with plane electronics and more about the poor handling of a rapidly moving phone on ground cell networks at the time. Enough flying phones would cause a significant performance degradation. The issue of handling fast switching was solved, but any "because security" or "because safety" laws tend to stay for a long time.
- dawnerd 3y agoI fly a lot and haven't head of this at all. Sounds like one of those stories that spread from someone thinking they saw something when in reality it was a crew with a phone checking seats for passengers.
- chgs 3y agoI’ve flown over a thousand times and have rarely used “airplane mode”. I’ve never seen any cabin crew using anything to “detect” cellular activity or even mentioning phones.
- lukan 3y agoPeople not turning on the airplane mode on their devices while in a plane. Sometimes they check (never happened to me though, but I avoid flying).
- outside1234 3y agoModern mobiles are not using frequencies anywhere close to those used by the plane for nav / comms anymore so this is not an issue (though your battery will run to zero as it frantically tries to find a tower)
- notyourwork 3y agoIMO phone battery is relatively fine. I've forgotten to enable airplane mode on a few flights.
- ghaff 3y agoI try to remember but I know I don't always and the battery has been relatively fine. And over the course of hundreds of flights I've never once seen or heard a flight attendant come around to tell a passenger to put their phone into airplane mode when I'm sure that maybe the majority of people just ignore the instruction to do so.

This will block frequencies used by these towers, with much more activity than they were designed to handle from ground-based devices. In the US, the ban on electronic devices in flight was initially put in place by the US Federal Communications Commission (FCC), not the FAA, for this reason. https://www.faa.gov/travelers/fly_safe/information https://www.faa.gov/travelers/fly_safe/information > The FCC and FAA ban cell phones for airborne use because its signals could interfere with critical aircraft instruments. Devices must be used in airplane mode or with the cellular connection disabled. You may use the WiFi connection on your device if the plane has an installed WiFi system and the airline allows its use. You'll note the FCC in there. While the aircraft instrumentation is the most immediate "reason for people to do this" that people can identify, disrupting ground communications is also there. Unfortunately, people are not that likely to do it based on "you'll inconvenience people using the cell phone towers that you fly over."
