Comments:Morning UC-12 event for a scheduled 2-event day; cooperative flight with the HU-25. Planned route: KLFI ATLIC ZIBUT TILED ZIBUT ATLIC KLFI. Takeoff from runway 26 immediately following HU-25 takeoff. Uneventful departure with north turn out to a climb on course direct ATLIC. Final cruising altitude was FL280 for the entire flight back to ATLIC. Initial ATC vectors for climbout, combined with a headwind at high altitude and a tailwind at low altitude, resulted in the UC-12 falling behind the HU-25 and being unable to catch up. Coincidence was maintained within 10 minutes, but was not optimal during outbound tracks. Further complicating coincidence was a convective build up approximately 40nm east of ZIBUT along the planned track. The UC-12 deviated north of track to circumnavigate, with a maximum lateral separation of 13nm north of desired ground track; cloud tops were above the performance envelope of the UC-12, estimated at ~ FL340, with a distinct anvil extending to the south of track that prevented a south deviation. UC-12 regained ground track approx.. 2/3 the distance from ZIBUT to TILED. HU-25 executed turn point approx.. 20 nm short of TILED; researchers confirmed desire for UC-12 to continue to same turn point then reverse—sacrificing opportunity to regain coincidence for gathering data on the same ground track as HU-25. Executed 30-deg bank angle reversal at turn point. On return leg to TILED, was able to maintain planned track—towering cumulus build ups had shifted northwards enough to maintain track. UC-12 did penetrate extended portion of anvil formation to maintain track. Commenced descent 12nm east of ATLIC for uneventful recovery at KLFI to runway 26. 4x dropsondes deployed: ZIBUT/Turn Point/half-way point back to ZIBUT/12nm east of ATLIC. Crew was Jamison, Wusk, Harper

Comments:Second flight of a two flight day. ACTIVATE statistical research flight. The plan was from KLFI - ATLIC - ZIBUT - N3630/W07145 - N3645/W06915 and reverse. Flight deviated from plan in that a fuel management issue on the HU25 prevented going out to the turn point, but not soon after the reversal to come home early, they resolved the issue and aircraft reversed course to continue as far as it could on original plan. They turned short by about 50 nm. The UC12 was delayed getting ATC clearance to make the early turn and had to continue east for an extra 30 or so miles. The UC12 had some tailwind help on the return and gained ground to have good coincidence for much of the return. UC-12 aircraft performed nominally and is ready for the next mission. Crew was Coldsnow, Wusk, Seaman.
