U.S. Air Force Senior Airman Venmeir Crowe, 86th Operations Support Squadron radar airfield weather systems technician, calibrates the instrument landing system using a portable instrument receiver at Ramstein Air Base, Germany, Oct. 8, 2020. The more accurate the degree marker is for the ILS, the more reliable it will be. To support Ramstein’s airlift mission, RAWS is on call 24/7 to maintain communication lines within airfield operations. (U.S. Air Force photo by Airman 1st Class John R. Wright)
