What is the primary function of Battery 2 in the Tradewind Initial NG system?

The primary function of Battery 2 in the Tradewind Initial NG system is to provide power for engine start. In multi-battery systems, it's crucial that a dedicated power source is available specifically to initiate engine operations, which can require a significant amount of electrical energy. Battery 2 fulfills this role by ensuring that sufficient voltage and current are supplied to start the engines reliably.

During engine start, a substantial draw on the battery is required, which is why having a designated battery for this purpose enhances overall system reliability. This design helps in achieving efficient engine ignition and operations without overloading other systems or batteries. The other functions related to battery management and system redundancy are important, but their primary roles focus on supporting the engines during startup scenarios, which is essential for successful aircraft operations.
