Electrostatic testing on the T28 |
- consultant was Jack Chapdelaine - sensitive points found at RFT, comm1 antenna and VOR antenna.All were remedied. |

In flight |
Pilot: Charlie Summers
Data in C:\t28\data\yr2002\f775\f4191336.raw - 536 buffers: good images, mostly ice - 0 buffers; non-charge mode - 2171 buffers:OK - 0 buffers: - worked ok - did not work! Flight was short, mainly to check the brakes.Telemetry worked OK.No heading! |

Instruments on T28 2DC HVPS Slow data Hail DMT FSSP |
In flight |
Pilot: Data in C:\t28\data\yr2002\f776\f5031551.raw 5056 buffers:good images 6093 buffers; non-charge mode, collects 10 buffers/sec!; 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. |

Donna uses tag 17 (before used for heading) to retrieve NO data from the NOx analyzer. New Heading Card (INS synchroheading).For the new heading card create tag #990. |

Instruments on T28 2DC HVPS Slow data Hail DMT NOx FSSP |
In flight |
Pilot: Tom Root 1st flight with TEI 42C-TL NOx analyzer installed. Initially some trouble getting computer to boot. Data in:c:\t28\yr2002\f777\f5231833.raw - 0 records - 829 buffers: lots of bad buffers (stuck bit case) - 2333 buffers: ok - 0 records - did not record any significant data - very small readings (up to 1 ppbv) - it worked this time |

NOx analyzer |
Ground test with all instruments on |
Calibration for NO. File: f6071605.raw Raw file looks ok; HVPS images look ok. 2DC images look ok. |

Instruments on T28 2DC HVPS Slow data Hail DMT NOx |
In flight |
Pilot: Charlie SummersData in : c:\t28\data\yr2002\f780\* - 18 buffers with small particles in it. - 3015 buffers: all bad images. -
- Donna adjusted HVPS image on the horizontal axes (x2) - 1798 buffers: ok - none - OK Note: Strong fires SW of Denver; could see the smoke; Charlie flew close to area of smoke, and NOx instrument had ~ 40 ppbv reading! |

Instrumentation tests in hangar |
Verified NO analyzer response at 43 and 90 ppbv Wired new switch for turning on analyzer in flight |

Instruments on T28 2DC HVPS Slow data Hail DMT NOx FSSP |
In flight |
Pilot: Charlie Summers Data in: c:\t28\data\yr2002\f781\f6120025.raw -1642 buffers: good images - 2266 buffers: some good buffers and some not good - 4970 buffers: ok - 620 buffers: looking good - nothing recorded Donna I noted 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. |
