U.S. Army Staff Sgt. Joseph Batts, A Company, 2nd Battalion, 210th Aviation Regiment medium repair supervisor course instructor, instructs Advanced Individual Training students while they work on the common avionics architecture system in a Chinook CH-47 training aircraft at Fort Eustis, Va., June 17, 2014. The newer model aircraft trainers look almost identical to active aircraft, but have different components added for training purposes, such as windows on sections that are typically covered and monitors mounted on the sides of the aircraft. These functions allow students to access manuals, and allow instructors to direct students through various tasks. (U.S. Air Force photo by Airman 1st Class Kimberly Nagle/Released)
