Many people don’t understand why they’re asked to disable electronic devices during takeoff and landing. So why do you have to turn your iPhone off? I got an answer from an airline pilot I happen to know:
“Some older aircraft do have extremely old school radios. Some do not even have GPS. So the FAA has decided two things:
- Since it is too contradictory for passengers and flight attendants to discriminate what aircraft they are on, and what should be the corresponding announcement, the same one is used for all aircraft.
- The FAA can not take time to test every new device as it’s released. In fact, such testing falls to near the bottom of its priority/to-do list.”
There you have it.
