It is worse than we realize. The majority of us that use WAAS approaches to its fullest advantage live at small airports WITHOUT a significantly low approach until WAAS was approved.
Before WAAS my only choice was a VOR approach. My home base (OVS), when using the VOR approach, the lowest we can descend is to 1000 feet AGL. Why? We are in a valley. The VOR approach takes us waaaay to close to bluffs with a lot of trees.
WITH the WAAS approach we can descend to 400 feet AGL and remain clear of the bluffs.
