Differences between the Pre- and Post-Calibrations were within acceptable levels, thus indicating generally stable response. Pre-Project calibrations have been used in the final data processing.
Calibration Maneuvers- 07/17/2002
RAF uses sets of in-flight maneuvers specifically designed to help evaluate the performance of the 3-D wind measurement system on the aircraft. Measurement errors for the wind variables were within normal performance standards.
