Bottom line

Under 14 CFR 91.503, the pilot in command of an airplane must ensure that pertinent aeronautical charts, in current and appropriate form, are accessible at the pilot station for each flight. Prior to taxiing, a current copy of the airport diagram should be available for use by the pilot.
