Everything is very wet this morning. No dew point in DPR prior to and after takeoff. Need to service it. After a little tinkering around, DPR got a descent dew point around 14:41.
RWO gone at 12:32:30. Waited 2 minutes for reboot with no success. Cycled power with breaker at 12:35. Could ping at 12:38. All red in status page and nan's in aeros. Now is the time to look at post flight data to see if it is there. Data 12:39:20 to 12:39:37. Back solid at 12:41:20. Took a screenshot of data in timeseries to compare to post flight data. See attached.
During preflight and after takeoff, 2D-10 end diode voltages really low. Pretty sure optics were wet prior to takeoff. Cycled power on just the 2D probe at 12:46. Diode voltages did not get larger. My assumption is that the optics have some ice on them. It appears the optics cleared at 12:54. All good now.
Occasionally, on the Status Page, the Onboard Cameras goes yellow and the time is lagging. This event lasts a couple seconds and then goes green again. Possibly, this is why Onboard Cameras went red on RF03 and stopped recording.
The INS seemed to look better this flight. Was it turned on earlier than in the previous few flights? If you could pass the word along to turn it on so that it can calibrate itself sufficiently (~20min before the plane starts moving?), that would be great. Thanks.

Radome tubing was drained of water post flight.

Kyle said that the INS is always turned on well before the 20 minute point.
