Uneducated writers thinking using phone during flight is the same thing as using phone on the ground. It's not.
Phones won't interfere with sensors and stuff on airplane. That much is true. However pilots need to communicate with all kinds of airport staff over FM radio and there, since it's an analogue signal, phones can cause that familiar disruption. It won't destroy equipment, but you will annoy pilots and might prolong departure time. Same thing when landing, you are coming from no signal zone and all of the sudden 100 phones starts talking at the same time when pilot is receiving instructions from the airport.
This is why you can talk during flight, but not takeoff.
That disruption is from a 2G/GSM handset. Those networks were turned off a decade ago.
Pilot here. Still on the A320 series it's obligatory to turn off the electrical devices for low visibility approaches (ILS Cat2/3) as aircraft's navigational systems are not protected (at least certified) against RF interference.
Stupid article.
As of Jan 31, 2024 any planes still not hardened their altimeters to meet group 4 performance are restricted from flying auto land, I/II ILS ; and for the most part the airlines still flying them aren’t using those planes in US airspace. It doesn’t mean that there aren’t any flying just that when they are they’re restricted by the FAA as to how they can operate.
Many more planes outside of US airspace, and plenty of those are rather older than 2024.
The article was explicitly discussing US airspace, hence my comment about FAA regulations. No one is doubting that there are a significant number of planes elsewhere in the world, governed by other countries air authorities, that don’t need to deploy a fix to their altimeters to ensure no interference from outside radio sources. Also as we’re only ending the second month of the year I’d speculate that near 99% of the planes in operation are non 2024 models.
Also, it’s important to note that it’s not the phones on the planes as much as the 5G towers in range of airports that cause the issues. That’s why the rollout of 5G-C towers near airports were on hold for several years to allow airlines to retrofit/upgrade their radio altimeters.
