Turning Off Your Phone Before Flying Turn off your phone before boarding any aircraft. To prevent possible interference with aircraft systems, the U.S. Federal Aviation Administration (FAA) regulations require you to have permission from a crew member to use your phone while the plane is on the ground. To prevent any risk of interference, FCC regulations prohibit using your phone while the plane is in the air. Turning Off Your Phone in Dangerous Areas To avoid interfering with blasting operations, turn off your phone when in a blasting area or in other areas with signs indicating that two-way radios should be turned off. Construction crews often use remote-control RF devices to set off explosives. Never transport or store flammable gas, liquid or explosives in the compartment of your vehicle that contains your phone or accessories. Turn off your phone when you're in any area that has a potentially explosive atmosphere. Although it's rare, your phone or its accessories could generate sparks. Sparks could cause an explosion or a fire resulting in bodily injury or even death. These areas are often, but not always, clearly marked. They include: • Fueling areas such as gas stations. • Below deck on boats. • Fuel or chemical transfer or storage facilities. • Areas where the air contains chemicals or particles such as grain, dust or metal powders.
