What percentage should the eFAD battery be at for the beginning of each flight?

The eFAD (Electronic Flight Attendant Device) battery should ideally be at 100% at the beginning of each flight to ensure optimal performance and reliability throughout the duration of the flight. Having a fully charged battery guarantees that the device can support all necessary functions, including communication, safety checks, and any additional operational tasks that may arise.

While a battery percentage of 25% may technically allow for some functionality, it is insufficient for a full flight’s duration and could lead to a scenario where the device loses power mid-flight, compromising flight attendants' access to crucial information and tools. Therefore, maintaining a fully charged battery is a standard requirement to avoid any operational disruptions.
