SDF question

[rcaligan]

According to the AIM, a SDF approach can be 6 or 12 degrees wide. So how can I find out the width of the SDF signal at DWU?

The A/FD doesn't say...
The approach plate doesn't say...

Examples that will expire at the end of September:

(1) Course sector width. The nominal course sector width must be 6°. When an operational advantage can be achieved, a nominal course sector width of 12° may be established. Course sector width must be adjusted and maintained within the limits of ±17 percent of the nominal value.

That is the general reg for the SDF which you already knew.

But I cannot find out how one tells which it is set to.

With a final approach course of 103 degrees, it can't be off the runway centerline by much. It almost looks like it wouldn't even be noticeable.

I do not believe there is any way for a pilot to determine from normal aviation pubs what the course width in degrees of an SDF approach course is.
