What is a key advantage of using an alternator over a generator in an aircraft?

Using an alternator in an aircraft provides a significant advantage in that it can produce sufficient electrical current even at low engine speeds. This capability is particularly important for aircraft since many operations, such as taxiing and takeoff, can occur at lower RPMs where generators may struggle to provide adequate power.

Unlike traditional generators, which typically rely on a consistent speed to maintain output levels, alternators can produce electricity consistently across a broader range of engine speeds. This means that pilots can rely on the alternator to power critical systems without the need for high engine RPMs, enhancing safety and operational flexibility.

While other factors, like weight and maintenance, are also relevant, the ability to generate power at low speeds directly addresses critical needs in aviation operations, making it a key advantage of using an alternator over a generator.
