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: TF02 and RF10 respectively. In each case the variations observed fell within acceptable limits.
PMS - 1-D Probe Bin Sizes
The SPP-100, SPP-200, SPP-300 and 260X 1-D probes were used on the project. The minimum droplet size (µm) for each sampling bin are listed below.
