6.7 hours
Takeoff at 1145 PST; Landing at 1825 for a 6.7 hour mission. Overall, the flight was a huge success. The instrument teams got an unexpected bonus when “Coach” flew over a line of thunderstorms in the San Joaquin Valley as the t-storms uplifted against the Sierra Nevada Mountain Range. Coach said he could see lightning flashes every 2 to 3 seconds. The instrument teams were ecstatic! The ER-2 took off late because after engine start, the airplane crew noticed the ER-2 losing seal pressure in the wheel well. When power was transferred back from engine to external power, all power shut down. This resulted in an INS failure and AVIRIS-NG shutting down. Coach went through the failure checklist, everything came back up without any fail lights. The wheel well seal was fixed, the engine was restarted, and everything was fine with the airplane and instruments. After a successful AVIRIS-NG NAV initialization, Coach went “thunderstorm hunting”. Coach noted that the AVIRIS-NG Q8 fail light was still intermittent. The fail light would go out for several minutes then would start flashing again. Coach flew over a severe thunderstorm east of San Francisco, an area where a tornado warning was issued. He then flew 6 laps over the line of thunderstorms approaching the Sierra Nevada Mountain Range where lightning flashes occurred every 2 to 3 seconds. After the 6 laps, Coach noticed that all of the AVIRIS-NG fail lights were on. AVIRIS-NG would not restart after stepping through the “AVIRIS-NG Fail” checklist. Coach then flew over the ocean. There was good clean air over the water. The EXRAD lines were completed including slow rolls over the water. After returning to the Edwards AFB airspace complex, Coach completed airplane maneuvers for the LIP instrument. The many maneuvers performed were for calibrating the many LIP instruments onboard the ER-2 airplane. Doing these maneuvers while in autopilot did not go well. Coach then flew the LIP maneuvers manually – much better results. Maneuvers included pitch up, pitch down with speed-brakes on and off, and 40 degree bank-angle rolls in both directions. Coach had to dodge clouds while performing the maneuvers. The LIP PI was very happy about the maneuvers completed. He expects a really good data set. After the first GOES-R flight, there were issues with the AVIRIS-NG, CPL, and EXRAD instruments. The instrument teams are troubleshooting so all instruments will be ready for a possible flight Thursday 23 March. Greg Coach Nelson was the pilot.
