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.

+ Certain sensors had to be replaced during the course of the experiment. Post-Calibration coefficients were used from the point of the exchange to the end of the project.

 

Calibration Maneuvers 05/27/2002, 06/15/2002, 06/18/2002

RAF uses sets of in-flight maneuvers specifically designed to help evaluate the performance of the 3-D wind measurement system on the aircraft. An additional set of maneuvers was flown during test flight TF03 (05/18/2002). Measurement errors for the wind variables were within normal performance standards.
