Differences between the Pre- and Post-Calibrations were generally within acceptable levels, thus indicating stable response from most sensors. The (*) denotes sensors that were replaced in the field. Pre-Project calibrations have been used in the final data processing, except where sensors were replaced.
Calibration Maneuvers
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.
