Anybody know why some departures at SJC use a loop departure? I flew out of SJC to Seattle and the AS 739 took off to the north but did a whole loop around the airport until finally heading towards Seattle. I've seen it many times also watching airport monitor. Anybody know why this pattern is at SJC? Also is there any other airports that use this look departure?

SJC arrivals from the north use about the same route as SFO arrivals except they descend to 12000 instead of 11000. Their only conflict is the SFO arrival stream from the south, and apparently they cross beneath with no problem.

>>>Do they do a loop arrival?
There may be a little confusion here, as the departure procedure in question isn't a general "loop", but has a specific name (LOUPE) that -sounds- like a generalized "loop".
All airports that have these SIDs/DPs (Standard Instrument Departures/Departure Procedures) and STARs (Standard Terminal Arrival Routes) will have them constructed in such a way that accounts for the traffic flows (both in and out) of other nearby airports.

I've been on flights that did a couple of loops on departure out of SJC. On arrivals from the north (such as PDX or SEA) they generally fly over Marin and west of the Golden Gate Bridge that provides a fantastic view if you're on the left side, then down the peninsula right over SFO, then a sharp left 180 turn south of SJC over the hills, then back north to land.

Ahhh, a topic I have pretty good knowledge of. My office is about 2 miles down the normal departure pattern for SJC and I watch the various aircraft fly by my window in my office. I also use that airport a lot when I have to travel.
There is one flight that does not follow the "loop" departure pattern. AA 129 SJC - AA), Japan">NRT, it heads straight west pretty much and then banks to the left after crossing the 237 freeway to clear SFO traffic and then off to AA), Japan">NRT.
I really like the UA terminal. It's odd, but I prefer using airstairs to board a aircraft. You get some great views of the AC that you normally don't see when using a jetway.
