U.S. Marine Corps student pilot Lt. Chris Lazoritz uses a checklist on his leg to remind him of the each of the pre-flight checks he needs to conduct on a T-6B Texan II aircraft at Naval Air Station Whiting Field, June 9, 2014. During pre-flight checks, instructor and student pilots ensure the aircraft is airworthy and safe to fly. The checklist includes a detailed list of steps to start the aircraft, conduct intermediate checks throughout the flight, depending on the phase of flight, and shut down the aircraft after landing.
