[edit] Most Lift

Is there any reference for the "produces the most lift" part of this claim? It seems reasonable enough, but I wasn't able to find any mention of it in any of the references.

The driven region, also called the propeller region, is the region at the end of the blades. Normally, it consists of about 30 percent of the radius. It is the driven region that produces the most lift, but also the most drag. The overall result is a deceleration in the rotation of the blade.

Good catch. It should probably read more like that the driven region is most responsible for the slowing effect on the rate of descent of the helicopter rather than the most lift. It is the angle of the TAF up and to the rear that slows the descent as the aircraft moves down and forward. The percentage of the driving region would mean that it is producing the most lift and the angle forward drives the rotor system allowing the driven region to provide the slowing of the rate of descent. --Born2flie 09:54, 15 July 2007 (UTC)
