Notes:

This flight was conducted to verify that the recent repair to the fuselage attack angle probe pressure lines resulted in valid measured fuselage differential and dynamic attack angle pressures.

There was one data gap: 135851Z - 135905Z.

RINU-1550 GPS altitude (ALTI1) experienced a dropout between

135851Z - 135905Z. The erroneous data was replaced with Novatel GPS (ALTNVL) altitude values using the following equation,

ALT1 = ALTNVL + 4.

Dewpoint sensor 2 (TDM2 [EdgeTech]) generated erroneous data between

143614Z – 144126Z. The erroneous data was replaced with dewpoint sensor 3 (TDM31 [Maycomm TDL]) output via the following equation,

TDM2 = TDM3 + 0.85

Measured fuselage static pressures, PSF, generated erroneous data between

193500Z – 193700Z. The erroneous data was removed and replace using statistical techniques with wingtip static pressure (PSW) as a reference.

All other instruments worked optimally during the flight.

There were twenty-eight (28) GPS dropsondes deployed...25 good 3 bad.

SPECIAL NOTE!!! The variable names dpj_wgs, dpj_was and dpj_wz in the netCDF file represent vertical ground speeds , vertical air speeds and vertical wind speeds, respectively, computed using Dave Jorgensen’s vertical wind algorithm. It is recommended that these values be used for vertical wind analysis.
