I wanted to solo and thought I was ready. I was sort of nonchalant about it too. After awhile I asked the CFI the "when" question. He told me "When you show me you're ready to be Pilot In Command." I think that's the best way to communicate the idea TO ME, as obviously that stuck.
He day he got out of the airplane he asked if I was ready, and I wasn't about to go back on my word, so I said "yeah" or something like it.
I took off and noticed the immediate loss of weight during climbout. On final,there was no way the airplane was touching the runway, so I performed a go-around at about 200 AGL. I did that about 3-4 times,getting progressively lower. At this point, I wanted nothing more than to get on the ground, but since I was now PIC, it was up to me and screaming for my mama wasn't happening, although that's how I felt.
After I got on the ground, he said that he was wondering what's happening (via radio) and said "go again". So guess what....shaking legs and all, I went again!
He said, "go again" after a few landings until he said "go until I tell you to stop", which I complied with.
Eventually I'd learned where to reduce power to idle such that I could do it earlier and earlier to come right over the threshold.
I told him that I was done, and made the decision to park the airplane at about dusk to see my then-fiancée smiling at me.
I was Pilot In Command.
