Yellow enclosed-cabin gyroplane in flight against a clear blue sky

Glossary

What spark plugs does a gyroplane use?

NGK plugs, in the specific heat range the engine manufacturer specifies for that model. Rotax names the exact plug for each engine variant in its maintenance manual, and it is not interchangeable with an automotive plug bought on assumption. Confirm the part number against the engine's own manual before replacing one.

That is the whole entry for now. The longer version, with the mechanics and worked examples, is still to be written. See autorotation for how those read once they exist.
