What must passengers do to carry PEDs containing lithium batteries exceeding the allowed watt-hour rating?

Passengers are required to obtain approval from the operator for carrying personal electronic devices (PEDs) that contain lithium batteries exceeding the allowed watt-hour rating. This is important because lithium batteries can pose a significant safety risk if they overheat or catch fire, particularly in the confined space of an aircraft.

Operators may have specific protocols in place to assess the risk of carrying such devices, and prior approval ensures that safety measures are adhered to. The operator will evaluate the device's potential hazards and may impose restrictions or require that certain procedures be followed, such as stowing the device in a particular way or carrying it in the cabin rather than checked luggage.

This requirement exists to mitigate risks associated with transporting devices with higher power capabilities, ensuring both the safety of all passengers and the compliance with aviation regulations.
