Lt. Simon Kraemer, left, 80th Flying Training Wing student, simulates a flight while fellow student pilot Lt. Espen Iversen follows a checklist at Sheppard Air Force Base, Texas, Aug. 29, 2018. This is the second level of simulators that pilots will work with. Some sim courses just require the pilot in training to follow a checklist procedure, but all of this is to instill the pilot with the confidence and muscle memory to be able to remember all the simple things while in a real flight.
