I understand that KSJC is a busy airport. I have done touch'n'gos at Oakland (also a busy Class C airport), but they have three dedicated runways for GA aircraft.
There is nothing about which runway is preferred for GA operations at SJC in the Airport Facility Directory notes.
What should I expect if planning an unannounced trip to SJC (arriving from the north/north-east)? Are touch-n-goes tolerated (i.e. staying in the pattern)? Which runway should I expect to be directed to? Is there anything else I should know?
I'm looking for local knowledge from someone with experience flying in the area, for example "GA operations are usually conducted on 30L, as the air carrier terminal is on the the other runway, and transient parking is adjacent to this runway" [I'm not sure this is the case, this is just an example of the type of information I'm looking for].
