What is the minimum voltage restriction for the main battery?

The minimum voltage restriction for the main battery is set at 22V DC. This specification is critical because the battery voltage directly impacts the performance and safety of the aircraft systems that rely on it. Operating below this minimum voltage can lead to insufficient power delivery to critical systems, which may compromise the effectiveness of electrical equipment and could pose a safety risk during flight operations.

Understanding the importance of maintaining the battery voltage above this threshold is essential for ensuring reliable aircraft operation. This minimum requirement helps to ensure that the electrical systems have adequate voltage to function properly, thus avoiding scenarios of inoperative equipment and potential failure during critical flight phases. Maintaining battery health and monitoring voltage levels is part of standard operating procedures for ensuring safety and reliability in aviation practices.
