Phase Airmen keep B-52s ready to fight
Senior Airman Cody Schillinger, 2nd Maintenance Squadron instrument and flight control systems journeyman, changes a bolt on an engine pressure ration transducer on Barksdale Air Force Base, La., Nov. 24, 2014. The transducer records intake and out-take pressure, finds a ratio and sends it to the pilots notifying them of current engine pressure.(U.S. Air Force photo/Airman 1st Class Mozer O. Da Cunha)
