Computation for Meteorological Variables Flight Number = 060627H Aircraft ID = N42RF Start 1233Z-2122Z Selection: Static Pressure Probe = psf Dynamic Pressure Probe = pqf1 Total Temperature Probe = tt2 Dewpoint Temp. Probe = tdm1 Vertical Accelerometer = acci2 Altimeter = ra159 INE Selection = 1 Dynamic Corrections = Yes Accelerometer-Same as Inertial Pressure-PDAF Collins GPS inoperative from 142900Z-143821Z Altitude from Inertial 1 and 2 are both erroneous. Drift Angle from Inertial 2 is off by ~75 degrees throughout the flight. Had profound impact on winds. Heading from Inertial 2 is way off by ~75 degrees. Edited TDM1 from 193839-194045 to lower RH.
