We acknowledge NOAA–AOC flight crews and engineers for their cooperation, especially Barry Damiano, who always fulfilled our requests. Ed Brown of NCAR and Barry Damiano performed the trailing cone flights. The optimization method for angle of attack calibration was the idea of Perry Fuehrer. We also acknowledge Ed Brown, Timothy Crawford, Barrie Leach, and Yolande Serra for their thoughtful reviews, and Xilong Song and Bryan Hannegan for their invaluable comments. This work was supported by National Science Foundation Grants ATM-9024436 and ATM-9110540 and NOAA Grant 56GP0154-01.
