some good buffers and lots of bad ones.
4745 buffers: ok -
194 buffers; good images. - worked ok. -
not working! Telemetry
worked ok. - FM test - P-static when in precip Due to lack of microphone for oxygen mask, pilot did not wear a
mask and flight was conducted at altitudes below 14 kft.
Precip was mainly small ice particles falling as virga. |

a response during taxi after landing. So the instrument must have been on? -
working good NOx analyzer warm up test ~ 30 minutes to settle to 1
ppbv. Contacted SPEC to sent copies of the bad buffers we recorded with HVPS and ask their opinion in how to fix the problem. |
