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. Sets of maneuvers were flown on one test flight and one research flight: TF01, RF10 and RF11 respectively. In each case the variations observed fell within acceptable limits.
PMS - 1-D Probe Bin Sizes
The SPPP100, SPP200, SPP300 and CDP probes were used on the project. The minimum droplet size (microns) for each sampling bin are listed below:
