Actually, the horsepower needed is more for a given velocity, (with higher RPM), at a shallow pitch setting. Just like in high gear. The power needed for given RPM is indeed lower at a shallow pitch. Eslonim 08:32, 1 October 2007 (UTC)

At shallow pitch setting, just like in low gear, LESS horsepower is needed to drive the prop, not MORE as the article states. Please correct if you agree with my reasoning. —Preceding unsigned comment added by LMF5000 (talk • contribs) 16:10, 20 September 2007 (UTC)

The reference link pointed to a page that no longer exists. I searched the site for an alternate page and replaced the old link with the one that seemed most appropriate.Es330td 12:40, 8 July 2006 (UTC)

Constant speed propeller is the common English usage in the US. CSU may be used elsewhere in the English speaking world.

The comment about LSA (light sport aircraft) regulations prohibiting CS props might be edited. The FAA wrote the LSA rules --everything in the regulations is aimed at keeping this simple (for manufacture, maintenance, and pilot operation). So, no CS props fits in with this thinking. 207.178.98.3 23:31, 30 April 2007 (UTC)

[edit] Merge with Controllable Pitch Propeller article?

Should this article be merged with the article on Controllable Pitch Propellers? After all, aren't Constant Speed (or Constant Velocity) Propellers just a name for Controllable Pitch Propellers when used in a certain application, or am I mis-understanding the difference?

A constant speed propeller is a specific type of variable pitch propeller. Most of the time "controllable pitch" means that the pitch angle is changed directly by the operator. Constant speed means that the operator sets a specific rotational speed, and then an automatic controller varies the pitch angle of the blades to vary the load on the propeller and thus hold it at the specified speed. Still, they're similar enough that I support the merge. Both articles are fairly short as is. Shreditor (talk) 04:53, 10 June 2008 (UTC)
