What is the minimum battery voltage required for engine start in the King Air 350?

The minimum battery voltage required for engine start in the King Air 350 is 24 volts. This requirement ensures that the battery has sufficient power to supply the necessary current to the starter motor and other essential systems during the engine start process. A voltage of 24 volts is standard for many aircraft systems, providing the required reliability and capability to handle the electrical demands during start-up. If the battery voltage falls below this threshold, it may not have the capacity to start the engines effectively, which could lead to starting failures or extended cranking times that can harm the engine or battery. Thus, maintaining battery voltage at or above 24 volts is critical for safe and efficient operation of the King Air 350.
