Flying into SNA for the first time on Thursday from San Jose in a 172. I expect to arrive at 9am, so I'm expecting the marine layer. Does anyone have advice on what to expect a) As a clearance route, b) Where I might be sent when I get there? Altitudes, waypoints, any local names I should familiarize myself with? I'm looking to do a WAAS approach. Any prevailing winds, East/West? How about on the departure. The 172 doesn't have much of a climb rate.
