Human Factors
I had been doing pattern work on RWY XX for about 45 minutes. All radio calls were made for each phase of flight; including upwind. As I was doing my sweep for traffic on final; and announcing at the same time; as my scan moved from the right back to forward; I noticed Aircraft Y just below me on a straight in approach to RWY XX. I immediately pulled up and turned right. I continued the right turn back to final and saw Aircraft Y landing on RWY XX. No radio announcements were made by Aircraft Y. At the altitude I was above Aircraft Y; I did not feel like we would have hit at that time; but had I not been above him and not able to see him; we very well could have hit as we got closer to the runway.While not required to fly a standard pattern by entering the pattern level on the 45; I believe requiring this type of pattern entry would increase safety. Just flying straight in with no radio calls; and without any regard for traffic in the pattern creates a hazardous situation.
RV12 pilot reported an NMAC with another light aircraft in the pattern at an uncontrolled airport.
