What is the minimum battery percentage required for an eFAD at the start of a duty day?

The minimum battery percentage required for an eFAD (Electronic Flight Bag) at the start of a duty day is 80%. This threshold ensures that the device has enough power to operate effectively throughout the entire duty period, which often includes flight planning, navigation, and other critical functions necessary for flight operations. Starting with a fully charged device reduces the risk of running out of battery during a flight, where access to flight information and other electronic resources is vital for safety and efficiency.

Maintaining at least 80% battery ensures that pilots can confidently rely on their eFAD for their tasks without interruptions from low battery warnings or shutdowns, prioritized for the safety of flight operations. Additionally, this standard aligns with the operational protocols established by airlines to ensure that technology aids pilots without constraints related to power availability.
