Notes:

There were no time/data gaps during this flight.

The King liquid water sensor was inoperative throughout the flight.

The Johnson Williams Liquid Water Sensor was inoperative from takeoff through 154030Z.

Altitude from inertial one and two were both inoperative throughout the entire flight.

Temperature and dewpoint values from sensor number 3 are also erroneous.

Radome pressure ports froze up from 205401Z-212200Z.

Data from dewpoint sensor number 2 was substituted into sensor number 1 from 142641Z-143121Z, 141701Z-142103Z, and from 210401Z-215800Z.

There were numerous times during the flight where the dewpoint temperature exceeded ambient temperature resulting in RH>100%. This was likely due to rain, a wet-bulb effect on the total temperature sensor, and/or an artificial warming of the dewpoint sensor as it tried to burn off excess moisture. No corrections were made to the data to bring the relative humidity values down below 120%.

Otherwise, all sensors worked optimally during this flight.

SPECIAL NOTE!!!	Locations 80, 81 and 82 of record five on the standard tape contain

vertical ground, vertical air and vertical speeds, respectively, computed

using Dave Jorgensen's vertical wind algorithm.

It is recommended that these values be used for vertical wind analysis.
