Seems that one of the figures (and the stupidest one) posted above is in absolute and direct contradiction with 14CFR91.126 (assuming left traffic)
(§91.126 Operating on or in the vicinity of an airport in Class G airspace.)
(b) Direction of turns. When approaching to land at an airport without an operating control tower in Class G airspace—
(1) Each pilot of an airplane must make all turns of that airplane to the left unless the airport displays approved light signals or visual markings indicating that turns should be made to the right, in which case the pilot must make all turns to the right;
Also note that it doesn't say just the turns in the traffic pattern, but in the vicinity.
Please tell me how entering on the 45 and making a RIGHT turn into the pattern is the same as making a left turn?
What's also stupid about the 45 entry: Lets spend all this time approaching the airport, getting a visual on a bunch of planes in the pattern, put it all together in our heads, and then turn our back to the ***-**** airport losing a visual on everything that's going on. There has been certificate action against pilots who made a right to final within 5 miles, and yet the FAA in all their "wisdom" says to do exactly that while even CLOSER to the airport. And we have idiots defending the practice. (Just keeping in theme with the thread title)
