Is it permissible for passengers to carry PMEDs fitted with lithium metal batteries, if the lithium metal content exceeds 2g but not 8g, without operator approval?

Is it permissible for passengers to carry PMEDs fitted with lithium metal batteries, if the lithium metal content exceeds 2g but not 8g, without operator approval?

• A. Yes
• B. No
• C. Only if in carry-on
• D. Only if in checked baggage

Answer: (B)

The correct approach regarding passengers carrying portable medical electronic devices (PMEDs) fitted with lithium metal batteries, where the lithium metal content exceeds 2g but not 8g, is that it is not permissible without operator approval. Lithium metal batteries pose a potential risk in aviation due to their flammability and the possibility of thermal runaway incidents. Regulations governing the transport of such batteries are based on safety considerations, especially in the confined environment of an aircraft. When the lithium content is between the specified limits, federal safety regulations typically require a strict policy to ensure the safety of all passengers and crew. Therefore, any device with lithium metal batteries exceeding 2g mandates specific operator approval to ensure compliance with safety guidelines. This critical safety measure is in place to mitigate risks associated with battery malfunctions during flight, underscoring the need for careful scrutiny of devices that exceed these limits.
