If battery power is below a certain level, what must be done before flight?

In the context of aviation operations, particularly regarding safety protocols, ensuring that the aircraft has adequate resources for navigation and flight is crucial. If battery power is below a certain threshold, printing paper approach charts becomes necessary because reliance on electronic systems can be compromised. By having physical navigation charts available, the crew ensures they can navigate safely to their destination without relying solely on potentially failing electronic devices.

Accessing printed charts is a critical part of maintaining situational awareness and ensuring compliance with aviation regulations concerning navigation. This step demonstrates a proactive approach to mitigate risks associated with low battery power, thus prioritizing safety in flight operations.
