Notes:

There was one time/data gaps during this flight which occurred from 151830Z-152521Z. Also, Ambient Temperatures from sensors one and two had data gaps from 173719Z-173738Z and from 173802Z-
173804Z.

Differences between dewpoint sensor one and two exceeded 2 degrees through much of the flight.

Data from dewpoint sensor 2 was substituted into dewpoint sensor 1 from 143104Z-143413Z with an offset of -2 degrees.

There was no altitude data from Inertial 1 and 2 throughout the entire flight.

From 143300Z through the end of the flight, Static Pressure from the wingtip and fuselage differed by 4 mb.

The King liquid water sensor (KLWC), differential attack pressure from the nose radome (PDAR), differential slip pressure from the nose radome (PDSR), dynamic pressure measured from the center port of the nose radome (PQR), total pressure measured at the nose radome (PTR), total and ambient temperature from sensor 3 (TA3,TT3), and dewpoint sensor 3 (TDM3, TD3), were all inoperative throughout the entire flight.

There were numerous times during the flight where the dewpoint temperature exceeded ambient temperature resulting in an 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 attempts were made to correct the data from dewpoint sensor 1 in order to bring the relative humidity values below 100%.

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.
