These printed reference pages, bound into every U.S. Navy pilot's flight logbook, defined the standardized letter codes used to categorize flight types and provided a table for recording special qualifications such as carrier landings, instrument flying, and catapult launches, each requiring sign-off by the commanding officer. Found in the personal logbook of naval aviator Wayne Bancroft, these pages illustrate the rigorous, standardized system used to track a Cold War-era pilot's progress toward full carrier qualification.
