So , in the sense of completeness, since this is about my training, I should include this last "lesson". As I mentioned before, my instructor held off on my airspace endorsement until after my check ride. We did some flying in C&D but he only "technically" cleared me for D as he wanted me to get some more practice in C. We fly to Islip, which can be busy between the general aviation flights and Southwest. So we planned to go there yesterday. I get to the airport early, have my breakfast, preflight my plane and get my paperwork ready. He's late. I text him/call him to no avail. So, since I'm ready to go I figure I'll just have a little flight. Shortly after I take off he calls me. Can't talk so he texts me and says he overslept be there in 15(young people). So I go back to the airport and wait. In the meantime it's getting a bit bumpy up there. We meet up, he briefs me on what to expect and then off we go. We takeoff and we get the ATIS, they're using 24 at Islip. I call approach, get my squawk code and they eventually hand me off to the tower. We're cleared for the straight in approach to 24(and we're miles away at the moment). We were expecting it to be busy but doesn't seem so. We land and taxi over to the avionics shop just to chill and discuss what's next. He wants me to contact clearance we're going to depart at 2000' rather than fly under the class C like we did the last time. He tells me to use C-R-A-F-T(clearance, route, altitude,frequency,transponder). We get the updated ATIS and I call clearance. Call ground and apparently now the tower is handling that so they have me switch to tower frequency. My instructor told me how they would probably have me taxi back for takeoff. Not! Proceed to A1, taxi onto runway 6 and back taxi. Hmm, things must really be slow if they want me to taxi on the active. Of course once I get on the runway they're like BTW we have a Southwest jet inbound so don't doddle. Taxi about 3/4 the way down, turn around and off we go. We get a couple of instructions to turn and then they clear us to squawk VFR. A little more bumpy now on our way back to KHWV. We land, taxing back to my parking spot and debrief. He signs off my logbook for class B and C ops. My first trip to a class C will probably be to KABE. I met a fellow Zenith owner(he just finished building his 650 last year)on line and he's based there. He's finishing up his sport pilot training and couldn't find a DPE so I hooked him up with the guy I used. Now to do some flying and enjoy.
