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?


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.


Thanks. My instrument training didn't cover SDF approaches. Are they
new or just few in number?
