SDF Approach?

wrote in : The Simplified Directional Facility is similar to a Localizer but may be offset from the runway and the course may be wider than a Localizer. How does an SDF approach differ from an Localizer-type Directional Aid (LDA) approach?

How does an SDF approach differ from an Localizer-type Directional Aid (LDA) approach? A LOC (whether aligned with the runway or LDA) will have a tighter width. While it varies in angular dimension because from approach to approach, the loc angular width is about 3 degrees. The SDF is 6 or 12.

Are they new or just few in number?
