Initially approaching the airport from the south, the pilot had overflown it at 2,000 feet, made a sweeping right turn, joined the pattern on the 45 and completed a routine approach and landing. The ground track of his second circuit was similar to that of the first, but he was slightly higher and considerably slower as he turned base to final a little more than a mile from the touchdown point, which is displaced 800 feet from the threshold. As he approached the runway, he got progressively slower and dropped below the glideslope, which was marked by a 4½-degree four-light PAPI. The last groundspeed and height recorded on his GPS, still a quarter mile from the aim point, were 45 knots and 69 feet agl; 16 seconds earlier, he had been at 49 knots and 197 feet. The second final approach was, on average, about 20 knots slower than the first.
