I was disappointed that Pia's article did not mention what I see as the greatest and most frequent breach of safety at non-towered airports: turns in the wrong direction. This is unfortunate because making turns in the pattern (when approaching to land) in the correct direction involves the only regulations specific to pattern work: 91.126 & 91.127 require that all turns be made in the correct direction for that runway. Everything that Pia described in this article is from the AIM which is recommended procedure, not regulatory. When a runway at a non-towered airport is designated as having left hand traffic (most runways) it is federal law, not a suggestion, to make all turns to the left.
Don't forget the 45-degree entry!! A lot of folks skip this, think it's unnecessary, etc. NOT TRUE! When I was a lad with only 100 hours, I entered an uncontrolled airport (now controlled) using the 45-degree approach. I established on downwind in my Cessna 172, when I look up: there's a Piper 30 feet diagonal-distance away from me, gliding into a straight-entry downwind exactly ahead of me!!! Yes, I took evasive action and no, we had no mid-air collision. But that guy didn't enter on a 45-degree path, or he would have seen me.
Now that I'm older, I know what I should have done: landed, walked over and popped the guy in the nose. He probably never knew how close we both came to the Infinite.
