How does the flight crew know if your phone is in airplane mode?
I was wondering, how does the flight crew know if your phone is on airplane mode?
Great question! Flight attendants use a device called a "PED" (Personal Electronic Device) detector to check if your phone is transmitting signals. This detects Bluetooth and Wi-Fi signals, as well as cellular signals. If your phone is not in airplane mode, it will appear on the device's screen.
