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: 145tfXX and 145rf12, respectively. An additional set of maneuvers was flown during flight 146rf02 of the IMPEX deployment. In each case the variations observed fell within acceptable limits.
PMS-1D Probe Bin Sizes
The SPP-100, SPP-200, SPP-300 and 260X 1-D probes were used on the project. The minimum droplet size (micrometers) for each sampling bin is listed below.
