The minimum battery power required on the iPad for dispatch should be:

The minimum battery power required on the iPad for dispatch is set at 30%. This threshold is established to ensure that the device has sufficient power to operate throughout the flight's critical phases, including preflight preparations, navigation, and any unforeseen circumstances that may arise during the flight. Having a 30% battery level helps prevent situations where the iPad could shut down unexpectedly, thereby avoiding potential disruptions to the flight plan or access to essential flight information. This standard ensures that flight crews can rely on the device for all necessary functions without the risk of running out of battery life when it is most needed.
