non-precision approach

non-precision approach
A radar-controlled approach or an approach flown by reference to navigational aids, in which electronic glide-slope information is not available. Examples are VOR (very high frequency omnidirectional radio-range), TACAN (tactical air navigation), LOC (localizer), ASR (airport surveillance radar), LDA (localizer-type directional aid), or SDF (simplified directional facility) approaches. Such approaches have higher minimums than precision approaches.

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.
