If hours count, 6,600 - of which about 4,500 are dual given.
1) There is no legal requirement to fly a pattern.
2) A pattern is recommended by the FAA in the AIM as a standard procedure.
3) I virtually always overfly my destination, if non-towered. Usually 500' or more above the pattern. Then fly out a bit and descend to enter a close downwind at about 45°.
Why?
a) It lets me look down at the wind direction indicator, which I can make out more clearly from above.
b) It allows me to check for obstructions or wildlife or "x's" on the runway.
c) I find it easier to spot possible NORDO planes from above.
d) I think there's less chance of a midair somewhere on a long final.
I'm not saying anyone must do it or is unsafe coming straight in. But once in a great while I hear of an accident or violation where I'm pretty sure it would not have happened had the pilot flown as I do. So, I'm trading maybe an extra tenth or two in the air for what I perceive as a tiny increase in safety.
Works for me!
Oh, and I honestly cannot remember the last time I got in a pi**ing contest with another pilot over right-of-way. I'm sure it has happened, but it's so rare as to be a non-issue the way I plan my arrivals.
