Just like our "0" above, you must report the Final approach fix if talking to ATC or FSS when inbound on a non-precision approach
For example, if circling to land is the terminating maneuver of a non-precision approach
, but the runway's approach lighting system is mop, the change in visibility standards may complicate things.
Ok, so we have one paragraph that compels us to report leaving the minimum glideslope intercept altitude (on glideslope) when conducting an ILS (lightning bolt symbol for you Aero Nay users) as well as to report crossing the Maltese-cross symbol on a non-precision approach
He earnestly claimed that the CDFA/CANPA (continuous descent) technique of flying a non-precision approach
in small planes is a bunch of hooey.
The standard minimum weather requirement for an alternate is 600-2 if there's a precision approach available and an 800-2 for a non-precision approach
If a non-precision approach
is roughly aligned with the runway, then that runway's number is included in the name of the approach--VOR Rwy 15, for instance.
So, we'll use the synonym, Constant Angle Non-Precision Approach
(CANPA) for a CDFA on a non-precision approach

With all the talk of continuous descent non-precision approach
techniques and vertical descent angles, you might think there's no place for dive-n-drive.
Of course, if the approach is a non-precision approach
or if the precision approach ends up breaking out at 500-600 feet above the ground, go ahead and use full flaps as needed.
Although it's a bit unsettling to know that you're responsible for your own obstacle clearance once you descend below minimums on a non-precision approach
, that's the way the game is played.
The leading culprit in improper IFR accidents is descending below the MDA on a non-precision approach
after passing the final approach fix.
