Have to be a bit more specific here. What runways are in use?
Their preferred configuration seems to be to land simultaneously on 28 Left and Right and to depart (simultaneously if needed) off 01 Left and Right.
Arrivals from southern California will usually be up over Monterey Bay, across the peninsula near Stanford and join the 28 final just outside the San Mateo tollbridge. From the east, they will often arrive over Modesto and pick up the visual over the south end of the bay, near Fremont. In either case they can land on either the left or right runway, traffic permitting.
From the north or northeast they might get routed over the Point Reyes route and do a sort of downwind leg down the middle of San Francisco bay. This could put them on a right downwind for either of the 28s, but most commonly to the right.
Landing on the 01s, is much the same but they angle over to a right base from near Coyote point. For a landing on the 19s, they maneuver over the middle of the bay. In decades of flying into SFO
I have never once landed, or even seen a plane land on the 10s though they are occasionally used for departures.
Been a long time (1964) since I landed a light plane (C-210) at SFO
. If I remember right, we did an angling downwind at lower height than the air carriers use, to 28R, out over the bay.
: The airport was under construction when I first saw it in about 1957 and it is still under construction.
Happiness is not seeing another trite Ste. Maarten photo all week long.
