Purpose of Flight:Science
Comments:4th HIWC Science Flight from KFLL. This flight did not include the Precipitation Imaging Probe (PIP) as it was removed for troubleshooting. The flight was flown over the Gulf of Mexico and resulted in a significant amount of research data as 17 data lines of approximately 10 minutes each were successfully completed during the mission. Significantly, on the final test point, we flew through the largest concentration of ice crystal particals to date on this deployment. This resulted in icing up both aircraft pitot booms and rendering the air data unreliable. The air data was affected for about 1.5 minutes and the anomaly cleared up shortly after exiting the high ice water content (HIWC) environment . This result was not unexpected and validated the type of pitot-boom icing and recovery expected in HIWC conditions. The aircraft returned in good shape and is ready for the next mission which will occur no earlier than Aug 19.
