Comments:Science flight for the HU-25 in support of ACTIVATE Campaign #4, conducted cooperatively with the UC-12 (2nd flight of the day). Departed Rwy08 with direct vectors down the coastline to KMQI, climbing to 5k ft MSL for initial transit. Winds were light and variable for majority of the flight. Research profiles conducted to KMQI through 3437N/07404W-3401N/07354W-3300N/07337W-3200N/07321W-3437N/07404W-KMQI-KLFI. Clear air modules executed throughout flight from 500 – 5500 ft MSL, with some quick in-cloud data collection at the turn-around point leveraging an isolated cloud formation at ~3500 ft MSL. Aircraft geolocation was initially separated by ~45 nmi due to UC-12 takeoff delays based on airfield traffic saturation. Compensated by flying HU-25 slower than nominal airspeeds and working a 360 degree turn at 3437N/07404W before proceeding down track for CALIPSO overpass. Geolocation was within 3 nmi for overpass (~30 nmi prior to 3300N/07337W at 1852UTC) and remained with ~10 nmi for remainder of flight. Upon reaching shoreline at KMQI, proceeded directly to KLFI due to fuel limitations collecting data between 3000-5000 ft MSL. All objectives were achieved and with no discrepancies noted.
