WebThey start by producing a current, which is constantly changing its value and polarity (also known as an Alternating Current or AC) and transforming it into a current that flows in a single direction (also known as a Direct Current or DC): DC Generator Components of a typical 24-volt aircraft DC generator include: WebAircraft have batteries, just like cars do, and batteries generate dc. There are a lot of things on aircraft that can run off dc power, and they can be operated just by switching the battery on, but then when the engines are started there are other systems that will use ac generated by an alternator on the engine.
