Airline passengers are often instructed to switch devices to airplane mode before takeoff, a rule some question. While experts like pilot Gary Coxe state that neglecting this practice has minimal consequences, they emphasize its importance as a courtesy. Potential risks include interference with cockpit communications, especially during critical phases like takeoff. The FAA mandates airplane mode to ensure safety, though regulations vary globally. The EU allows more mobile use, while the U.S. maintains stricter rules due to potential disruptions. Compliance is advised, as it conserves battery life and offers a break from connectivity, making it beneficial for passengers.
