Notes:

There were no time/data gaps during this flight.

From 011221Z-011225Z, attack angle (AKRD1) had a 9 degree spike and attack differential pressure (AP1) spiked. These spikes are possibly the result of running voltage through the sensors to try to trouble shoot dynamic slip pressure (DBP2).

From 003738Z through the end of the flight, dynamic slip pressure (DBP2) was reporting erroneous data.

From 005000Z through the end of the flight, SSDF2 and SSRD2 began reporting erroneous data.

From approximately 2017Z-2030Z, the relative humidity values were greater than 100%.

Upon climb and descent, dynamic sideslip pressures (DBP1 and DBP2) separated by 10 to 15 mb. Due to the absence of a third sensor for comparison, no judgement can be made on which sensor is performing more accurately

Temperature sensor two was erroneous throughout the entire flight.

The right dewpoint sensor was ~10 degrees too warm throughout the flight.

Otherwise, there were no problems with the flight.
