I really needed yesterday's flight/fright. For as frightened as I was, I flew pretty well, and if I can fly pretty well when I'm that freaked out, then my training is still effective.
Today, Mark and I took N824LB out and re-flew my flight from yesterday: SNS VOR 13, WVI LOC 02, in pretty much exactly the same weather. This time, I did better. No fear response (OK, perhaps a touch of anxiety dipping down into the clouds, but nothing major), and I was much more ahead of the airplane, even remembering to manually start the time at the FAF on the VOR approach. On the LOC, I misinterpreted the GPS and didn't realize I was past the FAF, so didn't descend until Mark prompted me. Then, for some reason, I had the hardest time getting the plane to stay in a 800fpm descent attitude, and my descent was more like 350 to 400 feet per minute. I got down to the minimums pretty much at the missed approach point, which is right at the beginning of the runway (being 700 feet above the runway at the beginning of the runway is not a great recipe for landing successfully). But, other than that, I handled it well.
I now feel ready for the trip on Friday. I'm so glad I did all that flying in the last week.
