Purpose of Flight:Science
Comments:Flew an over ocean wind flight profile, starting at 5,000'. Lower clouds covered good portion of the NW corner of the pattern. Eventually climbed to 10,000' to try and help keep the instrument cold. Even at 10k' the instrument was getting too warm and eventually the science was terminated due to the instrument condition. Ironically when the outside air is below 50 F the aircraft air-conditioning compressor locks out so it doesn't ice over. This means there is no aircraft cooling for the instrument early in the flight on days like today where the surface ambients are below or near 50 F. Once the instrument warmed up, the climb to higher altitude (and colder outside ambients) did not provide enough cooling for the instrument to recover. The research team is working on ideas to address this issue for future flights. The team still gathered some good data for about an hour of the flight. Next possible flight is set for Friday Nov 9th.
