CSU on a Cirrus?
Saw a Cirrus (SR20 I think) in the engineering hangar with its cowl off and wandered over to have a look. All very impressive but I couldn't see anything that looked like a CSU. Friendly engineer nearby also wandered over and he couldn't identify a CSU either and pronounced it a fixed pitch prop.
Now I'm sure all Cirrus' have this clever single lever AND a constant speed prop, so is it an electric unit or is it a hidden hydraulic unit, or is it really fixed pitch? I'm curious as I may need to do some training on our (single lever DA40 TDi) for someone who will upgrade to the Cirrus.
