190507-N-XK622-1092 PENSACOLA, Fla. (May 7, 2019) Aviation Support Equipment Technician Airman Recruit Lu Yin, from Los Angeles, and Airman Recruit Gabriel Romero from Berryville, Arkansas, perform a pre-operational inspection on the Naval Air Technical Training Center’s AMATROL T7082A Learning System. Instructors replaced outdated air conditioning training equipment with the new system, which helps modernize initial accession aviation support equipment technician “A” school training with a commercial off-the-shelf modernized air conditioning and refrigeration training aid. The system is designed to teach students critical concepts of compressors, condensers and other pressure control devices through a hands-on approach. (U.S. Navy photo by Lt. Ian Loomis/Released)
