Question: 1 / 400

What are the advantages of dual ignition in aircraft engines?

Provides a backup magneto system, increases the engine's horsepower.

Allows the engine to idle more smoothly, reduces fuel consumption.

Permits the use of lower grade fuels, increases the output power of the engine.

Dual ignition in aircraft engines allows for two spark plugs in each cylinder, creating a more powerful spark and thus igniting the air-fuel mixture more efficiently. This results in increased output power of the engine. Although options A, B, and D may also provide certain benefits to the engine, they are not directly related to the advantages of dual ignition. Option A refers to a backup system, which may be present in a dual ignition system but is not its main purpose. Option B mentions smoother idling and reduced fuel consumption, which are not necessarily caused by dual ignition. Option D refers to enhanced fuel efficiency and reduced maintenance costs, which could potentially be true for some dual ignition systems, but are not directly related to its main advantages.
