It's one of the options along with "enter a holding pattern at that
point". You're prompted for the course.


Is that a universal feature on IFR approach GPS?

You cannot do anything like that on my KLN-90B without suspending
waypoint sequencing. That would seem to me to be a barrier to RNAV
vectoring to final for ATC, since the variability of equipment in this
respect cannot be accounted for.


Can you not use your GPS to navigate to intercept a specified course to a
fix, and track that course, without a line on a moving map?

Yes, but it would require a bit of a home-made procedure to do it and
complete the approach. Here's how I could do it:

o Load the approach in the Flight Plan page
o Select direct to the FAF
o Put the GPS in OBS mode
o Set the OBS on the GPS CDI to the final approach course
o Use the CDI to intercept off the vector
o Just before the FAF, switch the GPS back to Leg mode to enable
sequencing

Or without a CDI?

Not sure what you mean here. I'd have to have something to indicate when I
was intercepting the course.

Have you ever flown an NDB approach with an ADF?

Eh?
